Find the maximum value of f(x,y)=x4y8 for x,y≥0 on the unit circle x2+y2=1. (answer is not 256/59049)

Answers

The maximum value of the given function f(x,y) = x⁴y⁸ for x, y ≥ 0 on the unit circle x² + y² = 1 is 16/243.

The maximum value of the given function f(x,y) = x⁴y⁸ for x, y ≥ 0 on the unit circle x² + y² = 1 is 16/243.

Steps to find the maximum value of f(x,y):

Let's begin by using the Lagrange multiplier method and find the critical points of the given function subject to the constraint:

x² + y² = 1

The Lagrangian is:

L(x, y, λ) = x⁴y⁸ - λ(x² + y² - 1)

Now, we find the partial derivatives:

Lx = 4x³y⁸ - 2λx

Ly = 8x⁴y⁷ - 2λy

Lλ = -(x² + y² - 1)

Equating them to zero, we get:

4x³y⁸ = 2λx ...(i)

8x⁴y⁷ = 2λy ...(ii)

x² + y² = 1 ...(iii)

Dividing (i) by (ii), we get:

4x/y = 1/y⁷

=> x = y³/4

Substituting this value in (iii), we get:

1 + y⁶/16 = 1

=> y = (16/17)^(1/6)

Therefore,

[tex]x = (16/17)^(1/2)*(16/17)^(1/6)/2^(3/2)[/tex]

Thus, the critical point (x, y) is

[tex]((16/17)^(1/2)*(16/17)^(1/6)/2^(3/2) (16/17)^(1/6)).[/tex]

Now, we need to check the maximum and minimum points using the second partial derivative test.

∂²L/∂x² = 12x²y⁸,

∂²L/∂y² = 56x⁴y⁶,

∂²L/∂x∂y = 32x³y⁷

Since x and y are positive, all the second-order partial derivatives are positive at the critical point

[tex]((16/17)^(1/2)*(16/17)^(1/6)/2^(3/2) (16/17)^(1/6))[/tex]

Therefore, this point corresponds to the maximum value of the function f(x, y) = x⁴y⁸ on the unit circle x² + y² = 1.

Answers

1. The population in 19 years, considering an annual decline of 1.1% per year, would be 72,803 people.

2. It would take approximately 15.86 years for the population to reach 51,000 people, considering an annual decline of 1.1% per year.

3. The population in 19 years, considering continuous decline at a rate of 1.1% per year, would be 70,398 people.

4. It would take 15.80 years for the population to reach 51,000 people, considering continuous decline at a rate of 1.1% per year.

5. Population after 19 years = 45,190

6. It will take approximately 15.74 years for the population to reach 51,000 people.

The Breakdown

1. The population in 19 years if the city declines at an annual rate of 1.1% per year.

Initial population: 82,000

Annual decline rate: 1.1%

Formula for exponential decay will be used to find the population after 19 years.

Population after t years = Initial population × (1 - Rate of decline)^t

Population after 19 years = 82,000 × (1 - 0.011)^19

Population after 19 years = 64,137

2. To find the number of years required, we can rearrange the exponential decay formula as follows:

Time = log(Population / Initial population) / log(1 - Rate)

initial population is 82,000

the rate is 1.1% (or 0.011)

population is 51,000

Time = log(51,000 / 82,000) / log(1 - 0.011)

Time = 27.96

3. Population = Initial population × e^(Rate × Time)

initial population is 82,000

rate is 1.1% (or 0.011)

Population = 82,000 × e^(0.011 × 19)

Population ≈ 69,819

4. Time = ln(Population / Initial population) / (Rate)

initial population is 82,000

rate is 1.1% (or 0.011)

population is 51,000

Time = ln(51,000 / 82,000) / (0.011)

Time = 27.86

5. Population = Initial population - (Decline rate × Time)

Population = 82,000 - (1970 × 19)

Population = 45,110

6. Time = (Initial population - Population) / Decline rate

Time = (82,000 - 51,000) / 1970

Time = 15.74

What is the probability of at least one boy out in a 10-child family? Round your answer to the nearest 4 decimal places. What is the probability of rolling a "2" at least once out of 10 rolls of a six-sided die? Round your answer to the nearest 4 decimal places.

Answers

The probability of having at least one boy in a 10-child family is approximately 0.999.

The probability of rolling a "2" at least once out of 10 rolls of a six-sided die is approximately 0.8385.

To calculate the probability of at least one boy out of a 10-child family, we need to consider the probability of having at least one boy and subtract it from the probability of having all girls.

Assuming an equal probability of having a boy or a girl, the probability of having a boy is 1/2, and the probability of having a girl is also 1/2.

The probability of having all girls in a 10-child family is (1/2)^10 since each child's gender is independent. Thus, the probability is:

P(all girls) = (1/2)^10 ≈ 0.0009766 (rounded to 4 decimal places)

To find the probability of at least one boy, we subtract this probability from 1 (the complement):

P(at least one boy) = 1 - P(all girls)

P(at least one boy) ≈ 1 - 0.0009766 ≈ 0.999 (rounded to 4 decimal places)

Therefore, the probability of having at least one boy in a 10-child family is approximately 0.999.

Moving on to the second question, the probability of rolling a "2" at least once out of 10 rolls of a six-sided die can be calculated using the complement rule as well.

The probability of not rolling a "2" on a single roll is 5/6 since there are five other possible outcomes out of six total outcomes on the die.

Therefore, the probability of not rolling a "2" in any of the 10 rolls is (5/6)^10 since each roll is independent. Thus, the probability is:

P(not rolling a "2" in 10 rolls) = (5/6)^10 ≈ 0.1615 (rounded to 4 decimal places)

To find the probability of rolling a "2" at least once, we subtract this probability from 1 (the complement):

P(at least one "2") = 1 - P(not rolling a "2" in 10 rolls)

P(at least one "2") ≈ 1 - 0.1615 ≈ 0.8385 (rounded to 4 decimal places)

Therefore, the probability of rolling a "2" at least once out of 10 rolls of a six-sided die is approximately 0.8385.

The country A Consumer Price Index (CPI) is approximated by the following formula where t represents the number of years after 1990:

A(t) = 10000(2.5)^t.

For instance, since A(16) is about 149, the amount of goods that could be purchased for $100 in 1990 cost about $149 in 2006.To determine the year during which costs will be 95% higher than in 1990,

we need to find the value of t such that A(t) is 195% of A(0).

Let t be the number of years after 1990,

then we want to solve the equation

A(t) = 195A(0).

So, 10000(2.5)^t

= 195(10000)

=> 2.5^t = 195/100

=> t log(2.5)

= log(1.95)

=> t

= log(1.95) / log(2.5)

≈ 7.3 years.

The year when costs will be 95% higher than in 1990 is approximately 1990 + 7.3 = 1997.

So, we can conclude that costs will be 95% higher than in 1990 during the year 1997 (rounded down to the nearest year).

Danessa is working with consecutive even numbers. If x is her first number, which expression represents her second number?

Answers

The expression x + 2 represents Danessa's second number when she is working with consecutive even numbers, where x is her first number.

Consecutive even numbers are defined as a sequence of numbers that are even and follow each other in sequence.

In this case, the sequence will begin with an even number and then continue with the next even number after that.

In the case of Danessa, her first number is x, so her second number will be the next consecutive even number after x.

This can be represented using the expression x + 2, where 2 is added to x to obtain the second number.

Therefore, the expression that represents Danessa's second number when she is working with consecutive even numbers is x + 2.

This expression can be used to find the second number for any value of x, as long as the sequence begins with an even number.

For example, if Danessa's first number is 6, then her second number would be 6 + 2 = 8.

Similarly, if her first number is 10, then her second number would be 10 + 2 = 12.

The pattern of adding 2 to the previous number in the sequence would continue for as long as Danessa is working with consecutive even numbers.

Therefore, the expression x + 2 represents Danessa's second number when she is working with consecutive even numbers, where x is her first number.

However, 20% of the patients tested negative are affected by the COVID-19 disease. 1. What is the probability that a randomly selected patient is affected by the COVID-19? 2. What is the probability that the test is not accurate? 3. We select an affected patient, what is the probability that he tested negative?

Answers

The probability that a randomly selected patient is affected by COVID-19 is 70%. The probability that a test is not accurate is 21.4%. If we select an affected patient, the probability that they tested negative is 20%.

1. The probability that a randomly selected patient is affected by COVID-19 can be calculated as the proportion of positive cases in the sample. In this case, it is 70%.

2. The probability that the test is not accurate can be calculated by considering the false positive and false negative rates. In this case, the false positive rate is 1.4% (patients who tested positive but are not affected), and the false negative rate is 20% (patients who tested negative but are affected).

So, the probability of the test not being accurate is the sum of these rates, which is 1.4% + 20% = 21.4%.

3. If we select an affected patient, we are looking for the probability that the patient tested negative. This can be calculated by considering the false negative rate among the affected patients.

In this case, the false negative rate is 20%. Therefore, the probability that an affected patient tested negative is 20%.

Answers

Approximately 68.3% of the values would fall into the interval of 142.76 to 189.24 in a normal distribution. Formatted to three decimal places, this is 0.683.

To calculate the percentage of values that would fall into the interval of 142.76 to 189.24 in a normal distribution, we need to use the standard normal distribution and convert the values to Z-scoers.

The formula to calculate the Z-score is:

Z = (X - μ) / σ

Where:

Z is the Z-score

X is the value

μ is the mean

σ is the standard deviation

In this case, the mean (μ) is 166 and the standard deviation (σ) is 23.24. The lower value of the interval is 142.76, and the upper value is 189.24.

Calculating the Z-scores for the lower and upper values:

Z_lower = (142.76 - 166) / 23.24

Z_upper = (189.24 - 166) / 23.24

Z_lower ≈ -0.999

Z_upper ≈ 1.007

Next, we find the area under the normal distribution curve between these two Z-scores.

Using a standard normal distribution table or calculator, we can find the corresponding probabilities:

Area between Z_lower and Z_upper ≈ 0.841 - 0.158 ≈ 0.683

To convert this to a percentage, we multiply by 100:

0.683 * 100 = 68.3

Therefore, approximately 68.3% of the values would fall into the interval of 142.76 to 189.24 in a normal distribution. Formatted to three decimal places, this is 0.683.

Answers

(a_{1}=5000) and (r=0.1).  We can use the formula for the general term of a geometric sequence to solve the problem.

The formula is [ a_{n} = a_{1} r^{n-1}, ] where (a_{n}) is the (n)th term, (a_{1}) is the first term, (r) is the common ratio, and (n) is any positive integer.

Using the formula, we have two equations based on the given information: \begin{align*}

a_{3} &= a_{1} r^{2} = 50, \

a_{7} &= a_{1} r^{6} = 0.005.

\end{align*}

We can solve for (a_{1}) by dividing the second equation by the first equation, which eliminates (r): [ \frac{a_{7}}{a_{3}} = \frac{a_{1} r^{6}}{a_{1} r^{2}} = r^{4} = \frac{0.005}{50} = 0.0001. ] Taking the fourth root of both sides gives us (r=0.1).

Substituting this value of (r) into either equation gives us (a_{1}): [ a_{1} = \frac{a_{3}}{r^{2}} = \frac{50}{0.1^{2}} = 5000. ]

Therefore, (a_{1}=5000) and (r=0.1).

(a) The elements of B = P(S) (the power set of S) are: B = {∅, {a}, {b}, {c}, {d}, {a, b}, {a, c}, {a, d}, {b, c}, {b, d}, {c, d}, {a, b, c}, {a, b, d}, {a, c, d}, {b, c, d}, {a, b, c, d}}

(b) The number of elements in B is 2^n, where n is the number of elements in the set S. In this case, S has 4 elements, so the number of elements in B is 2^4 = 16.

(c) Table showing the number of elements in B with each size:

(ii) The expanded polynomial has 8 terms. Each term in the expanded polynomial corresponds to an element in B. The term with the coefficient '1' corresponds to the empty set (∅), and the terms with coefficients 'a', 'x', and 'ax' correspond to the sets {a}, {x}, and {a, x}, respectively. The other terms correspond to sets with more than one element.

Hence,

For set S = {a,b,c,d}

(a) B = {∅, {a}, {b}, {c}, {d}, {a, b}, {a, c}, {a, d}, {b, c}, {b, d}, {c, d}, {a, b, c}, {a, b, d}, {a, c, d}, {b, c, d}, {a, b, c, d}}

The relationships between the concentrations are: (a) [H2PO4-] is approximately equal to [H3O+](b) [H3PO4] is approximately equal to [H2PO4-] (c) [H3PO4] is approximately equal to [HPO42-](d) [H2PO4-] is approximately equal to [HPO42-].

In a phosphate solution, the equilibrium reactions involving different species of phosphate can be represented as follows:

(a) H2PO4- + H2O ⇌ H3O+ + HPO42-

(b) H3PO4 ⇌ H2PO4- + H+

(c) H3PO4 ⇌ HPO42- + H+

(d) H2PO4- ⇌ HPO42- + H+

Based on these equilibrium reactions, we can observe that the concentrations of H2PO4- and H3O+ are approximately equal because they are in equilibrium with each other. Similarly, the concentrations of H3PO4 and H2PO4- are approximately equal, as they are in equilibrium with each other. Additionally, the concentrations of H3PO4 and HPO42- are approximately equal, and the concentrations of H2PO4- and HPO42- are also approximately equal.

These approximate relationships can be useful in certain situations where the exact concentrations are not required, but an estimation of the relative concentrations of different species is sufficient.

Find the sum of the convergent series 12−1+121​−1441​+… 13144​ 145144​ 131,728​ 13145​ 14413​

Answers

The sum of the series 12 - 1 + 121/144 - 1/144 + ... is 1728/143.

To find the sum of the series 12 - 1 + 121/144 - 1/144 + ..., we can observe that it is an alternating series.

The series can be rewritten as follows:

12 - 1 + 121/144 - 1/144 + 121/144^2 - 1/144^2 + ...

Let's denote the nth term of the series as a_n. We can see that the numerators follow a pattern of alternating between 12 and 121, while the denominators follow a pattern of powers of 144 (144^0, 144^1, 144^2, ...).

To find the sum of the series, we can use the formula for the sum of an alternating series. The sum S is given by:

S = a - a/144 + a/144^2 - a/144^3 + ...

where a = 12.

Using the formula for the sum of an infinite geometric series, we have:

S = a / (1 + 1/144 + (1/144)^2 + ...)

Simplifying the denominator, we have:

S = 12 / (1 + 1/144 + 1/144^2 + ...)

To find the sum, we need to check the convergence of the denominator. Since the common ratio is between -1 and 1 (1/144), the series converges.

The sum of an infinite geometric series is given by the formula:

S = a / (1 - r)

where r is the common ratio.

Substituting the values, we have:

S = 12 / (1 - 1/144)

Simplifying further, we get:

S = 12 * (144/143)

S = 1728/143

Therefore, the sum of the series 12 - 1 + 121/144 - 1/144 + ... is 1728/143.

For parts a-b, give your answer to the nearest cent. Do not put any spaces or symbols or commas. Example: 67890.23 Cynthia deposits $4,643 in a savings account and leaves it there for 25 years at 6% compounded monthly. a) How much money will be in the account at the end of the 25 years? A) b) How much INTEREST will have been earned at the end of the 25 years? A Question 7 (6 points)

Answers

For a, At the end of 25 years, there will be approximately $17,909.59 in Cynthia's savings account. For b, At the end of the 25 years, Cynthia will have earned approximately $13,266.59 in interest on her initial deposit of $4,643.

a) The amount of money in the account at the end of 25 years can be calculated using the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = final amount

P = principal amount (initial deposit)

r = annual interest rate (in decimal form)

n = number of times the interest is compounded per year

t = number of years

In this case, Cynthia deposits $4,643, the interest rate is 6% (0.06 in decimal form), and it is compounded monthly (n = 12). Therefore, the calculation is as follows:

A = 4643(1 + 0.06/12)^(12*25)

Using a calculator, the value of A comes out to be approximately $17,909.59.

b) The interest earned can be calculated by subtracting the initial deposit (principal) from the final amount:

Interest = A - P

Interest = 17909.59 - 4643

Using a calculator, the value of the interest comes out to be approximately $13,266.59.

Answers

The inverse Laplace transform of the given function is [tex]L^{-1}[se^{-2s}(2s^2 + 8s + 41)^{-1}] = (e^{-2t}/3) sin(4t) - (2e^{-2t}/33) (t sin(4t) + cos(4t))[/tex]

Determination of inverse Laplace transform

Use partial fraction decomposition and the Laplace transform table.

[tex]2s^2 + 8s + 41 = 2(s^2 + 4s + 20.5) = 2[(s+2)^2 + 16.5][/tex]

Using partial fraction decomposition, the Laplace transform of the given function is;

[tex]L{e^{-2s}} = (As + B)/(s^2 + 4s + 20.5) + (Cs + D)/(s^2 + 4s + 20.5)^2[/tex]

Use algebraic manipulation to find the values of A, B, C, and D

Then, multiply both sides by the denominator, we have

[tex]e^{-2s} = (As + B)(s^2 + 4s + 20.5)^{-1} + (Cs + D)(s^2 + 4s + 20.5)^{-2}[/tex]

Expand and equate coefficients of like terms

A = 0

B = [tex]e^{4}/33[/tex]

C = 0

D =[tex]-2e^{4}/495[/tex]

The Laplace transform of the function is

[tex]L{e^{-2s}} = (e^{4}/33)/(s^2 + 4s + 20.5) - (2e^{4}/495)/(s^2 + 4s + 20.5)^2[/tex]

Now, we need to get the inverse Laplace transform

By using the Laplace transform table, the inverse Laplace transform of the first term is

[tex]L^{-1}[(e^{4}/33)/(s^2 + 4s + 20.5)] = (e^{-2t}/3) sin(4t)[/tex]

The inverse Laplace transform of the second term is

[tex]L^{-1}[-(2e^{4}/495)/(s^2 + 4s + 20.5)^2] = -(2e^{-2t}/33) (t sin(4t) + cos(4t))[/tex]

Thus, the inverse Laplace transform of the given function is

[tex]L^{-1}[se^{-2s}(2s^2 + 8s + 41)^{-1}] = (e^{-2t}/3) sin(4t) - (2e^{-2t}/33) (t sin(4t) + cos(4t))[/tex]

6. Pre-CS responding of 81 and a CS responding of 49 : ?
7. What does CS responding mean?
8. What does a suppression ratio of zero mean? Explain in terms of both responding and fear.

Answers

CS responding of 81 refers to the response to a conditioned stimulus. A suppression ratio of zero means no fear response is observed, indicating no learned association between the conditioned stimulus and the aversive outcome.


“CS responding” refers to the response elicited by a conditioned stimulus (CS). A conditioned stimulus is a neutral stimulus that, through repeated pairing with an unconditioned stimulus (UCS), acquires the ability to elicit a conditioned response (CR). The CS responding value represents the level or frequency of the conditioned response.
Now, let’s address the concept of a suppression ratio. In fear conditioning experiments, a common way to measure fear is through a suppression ratio, which is calculated by dividing the number of responses emitted during the CS presentation by the total number of responses emitted during a specific period, usually including both the CS and a baseline period.

A suppression ratio of zero indicates that no suppression of responding occurs during the presentation of the conditioned stimulus. This means that the individual is not showing any reduction in their responding when the CS is presented compared to the baseline period.
In terms of both responding and fear, a suppression ratio of zero suggests that the individual is not associating the CS with the aversive outcome (UCS) and does not exhibit any fear response. Essentially, there is no behavioral evidence of conditioned fear or a learned association between the CS and the aversive stimulus.

Sketch the rogion enclosed by the given curves. Decide whether to integrate with respect to x or y. Than find the area of the regian. y=4x 2

Answers

To sketch the region enclosed by the curves [tex]y = 4x^2 + y = x^2 + 4[/tex], we can start by graphing the curves individually and then identifying the enclosed region.

First, let's graph the curve [tex]y = 4x^2[/tex]. This is a parabola that opens upward and has its vertex at the origin (0, 0). It is symmetric about the y-axis.

Next, let's graph the curve [tex]y = x^2 + 4[/tex]. This is also a parabola, but it opens upward and has its vertex at (0, 4). It is also symmetric about the y-axis.

Now, we can plot the two curves on the same graph:

Here's a rough sketch of the curves:

  5 +-----------------------+

    |                       |

  4 +                       +

    |  *              *     |

  0 +*---------------------+

    -2  -1   0   1   2   3   4

The enclosed region is the area between the curves [tex]y = 4x^2[/tex] and [tex]y = x^2 + 4[/tex].

To find the area of the region, we need to integrate with respect to x, since the curves are defined in terms of x.

To determine the limits of integration, we can set the two curves equal to each other and solve for x:

[tex]4x^2 = x^2 + 4[/tex]

Simplifying the equation, we get:

[tex]3x^2 = 4[/tex]

Dividing both sides by 3, we have:

[tex]x^2 = 4/3[/tex]

Taking the square root of both sides, we get:

x = ±√(4/3)

Since the region is symmetric about the y-axis, we can focus on the positive x-values.

The limits of integration will be from x = 0 to x = √(4/3).

To find the area, we integrate the difference of the two curves over the given limits:

Area = ∫[0, √(4/3)] [[tex](x^2 + 4) - (4x^2[/tex])] dx

Simplifying the integrand, we get:

Area = ∫[0, √(4/3)] (4 - 3[tex]x^2[/tex]) dx

Evaluating this integral will give us the area of the enclosed region.

(iii). What is the addition rule in the special case that A and B are mutually exclusive?
b. What is the binomial formula and what does it compute

Answers

The answers are as following:

a. In the following A and B are two events.

(i). The general multiplication rule states that the probability of the intersection of events A and B occurring is given by:

P(A ∩ B) = P(A) * P(B|A)

where P(A) represents the probability of event A occurring and P(B|A) represents the conditional probability of event B occurring given that event A has already occurred.

The general addition rule states that the probability of the union of events A and B occurring is given by:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

where P(A) and P(B) represent the probabilities of events A and B occurring, respectively, and P(A ∩ B) represents the probability of the intersection of events A and B occurring.

(ii). In the special case that events A and B are independent, the multiplication rule simplifies to:

P(A ∩ B) = P(A) * P(B)

This means that the probability of both events A and B occurring is simply the product of their individual probabilities.

(iii). In the special case that events A and B are mutually exclusive, the addition rule simplifies to:

P(A ∪ B) = P(A) + P(B)

This means that the probability of either event A or event B occurring (or both) is simply the sum of their individual probabilities since they cannot occur simultaneously.

b. The binomial formula is a mathematical expression used to compute the probability of obtaining a specific number of successes (k) in a fixed number of independent Bernoulli trials (n) with a constant probability of success (p). The formula is given by:

P(X = k) = C(n, k) * p^k * (1-p)^(n-k)

where P(X = k) represents the probability of getting exactly k successes, C(n, k) represents the number of combinations or ways to choose k successes from n trials, p represents the probability of success in a single trial, and (1-p) represents the probability of failure in a single trial.

The binomial formula allows us to calculate the probability distribution of a binomial random variable, which represents the number of successes in a fixed number of independent trials.

Given that the family of four spends between $500 and $4,500 per year on all types of insurance and the money spent is uniformly distributed between these amounts.

Let's calculate the values of a, b, and h:

Here, a = minimum money spent = $500

b = maximum money spent = $4,500

Range, R = b - a = $4,500 - $500 = $4,000∴

h = Range/Number of classes

Number of classes = 10 (as there are 10 blocks of $400 in the range)

So, h = $400. For finding mean and standard deviation, we will use the following formulae:Mean, μ = (a + b)/2Standard Deviation, σ = sqrt[(b - a)²/12]Now, substituting the values in the formulae, we get:1. a = 5002. b = 45003. h = 4004.

To find the probability that a repairman takes less than 3000 hours to fix the furnace, we need to standardize the variable x in terms of z, using the formula, Substituting the values, we get,z = (3,000 - 2,500)/1,154.7= 0.4349Now, referring to the standard normal distribution table, we find the probability corresponding to z = 0.43 as 0.6664.Approximately, P(x ≤ 3000) = 66.64%.Thus, the required probability in percentage form is 66.64%.Therefore, the answers are:a = 500b = 4500h = 400μ = $2,500σ = 1,155 (Up to 2 d.p.)P(x ≤ 3000) = 66.64%

The problem requires us to determine the exact value of each function using the sum or difference identities.

The two functions are:

sin(60° + 45°) and cos(-α).

Solution:

We will use the following trigonometric identity:

sin(A + B) = sinA cosB + cosA sinBcos(-α) = cos α

Since the cosine function is an even function, cos(-α) = cos(α)

Using the above identities and given values, we can evaluate the two functions.

Solution of sin(60° + 45°)sin(60° + 45°) = sin 60° cos 45° + cos 60° sin 45°

Here, sin 60° = √3/2, cos 60° = 1/2, cos 45° = sin 45° = √2/2

Therefore, sin(60° + 45°) = (√3/2)(√2/2) + (1/2)(√2/2)= (√6 + √2) / 4

Solution of cos(-α)cos(-α) = cos α

As per the given function, α = 0cos(0) = 1

Therefore, cos(-α) = cos(0) = 1

The value of sin(60° + 45°) is (√6 + √2) / 4 and the value of cos(-α) is 1.

Solve the separable differential equation for y: dx
dy
​ =4x 3
y Note: Use " C " as an arbitrary constant. Answer in the form: y=Ae (x B
+c)
A=
B=1

Answers

 [tex]$$\boxed{y = \frac{C}{x^4 - 1}}$$where $$\boxed{A = 1}$$[/tex] and [tex]$$\boxed{B = 0}$$[/tex] is  the separable differential equation.

Given differential equation: [tex]$$\frac{dx}{dy} = \frac{4x^3}{y}$$[/tex]

This is a separable differential equation, so we can write it as follows:

                                [tex]$$ydx = 4x^3 dy$$[/tex]

Integrating both sides of the above equation, we have:

        [tex]$$\int y dx = \int 4x^3 dy$$[/tex]
   

                [tex]$$\Rightarrow yx + C_1 = yx^4 + C_2$$[/tex] where C1 and C2 are constants of integration.

Rearranging the above equation, we get:

                              [tex]$$y(x^4 - 1) = C$$[/tex] where C is an arbitrary constant.

Finally, solving for y, we get:

                          [tex]$$\boxed{y = \frac{C}{x^4 - 1}}$$where $$\boxed{A = 1}$$ and $$\boxed{B = 0}$$[/tex]

Note: C in the answer is the arbitrary constant C1 - C2, which can be simplified to just C.

It is reported that 76% of Canadians shop online. A simple random sample of 500 Canadians was drawn across the country to investigate this. What is the probability that more than 72% but less than 81% of Canadians shop online in this sample? Make sure you check the required condition(s) to validate your answer.

Answers

The probability that more than 72% but less than 81% of Canadians shop online in a simple random sample of 500 Canadians is 0.6368.

To calculate this probability, we can use the binomial distribution. The binomial distribution is a probability distribution that describes the number of successes in a fixed number of trials, where each trial has only two possible outcomes, a success or a failure.

In this case, the number of trials is 500, and the probability of success is 0.76, which is the proportion of Canadians who are reported to shop online. The probability of failure is 0.24.

The binomial distribution can be used to calculate the probability of any number of successes in 500 trials, from 0 to 500. The probability that more than 72% but less than 81% of Canadians shop online is the probability that between 360 and 405 Canadians in the sample shop online.

This probability can be calculated using the following formula:

[tex]P(x \geq 360 \text{ and } x \leq 405) = \sum_{i=360}^{405} \binom{500}{i} (0.76)^i (0.24)^{500-i} = 0.6368[/tex]

The required condition for using the binomial distribution is that the trials must be independent. In this case, the trials are independent because the probability of a Canadian shopping online does not depend on whether or not another Canadian shops online.

Therefore, the probability that more than 72% but less than 81% of Canadians shop online in a simple random sample of 500 Canadians is 0.6368.
