The weight at the 80th percentile for women is 163 lbs, and for men is 176 lbs.

To find the weight at the 80th percentile for each gender, we first need to arrange the weights in ascending order for both men and women:

Women's weights: 109, 112, 115, 116, 121, 122, 124, 124, 126, 133, 134, 142, 142, 161, 165, 177, 179, 189, 201, 229

Men's weights: 149, 150, 161, 163, 166, 168, 169, 175, 177, 184, 189, 222

For women, the 80th percentile corresponds to the weight at the 80th percentile rank. To calculate this, we can use the formula:

Percentile rank = [tex](p/100) \times (n + 1)[/tex]

where p is the percentile (80) and n is the total number of data points (in this case, 20 for women).

For women, the 80th percentile rank is [tex](80/100) \times (20 + 1) = 16.2[/tex], which falls between the 16th and 17th data points in the ordered list. Therefore, the weight at the 80th percentile for women is the average of these two values:

Weight at 80th percentile for women = (161 + 165) / 2 = 163 lbs.

For men, we can follow the same process. The 80th percentile rank for men is [tex](80/100) \times (12 + 1) = 9.6[/tex], which falls between the 9th and 10th data points. The weight at the 80th percentile for men is the average of these two values:

Weight at 80th percentile for men = (175 + 177) / 2 = 176 lbs.

The original number is 10t + o = 10(10) + 7 = 107.

Let's call the tens digit of the original number "t" and the ones digit "o".

From the problem statement, we know that:

t + o = 17   (Equation 1)

And we also know that the number with the digits reversed is thirty more than 5 times the tens' digit of the original number. We can express this as an equation:

10o + t = 5t + 30   (Equation 2)

We can simplify Equation 2 by subtracting t from both sides:

10o = 4t + 30

Now we can substitute Equation 1 into this equation to eliminate o:

10(17-t) = 4t + 30

Simplifying this equation gives us:

170 - 10t = 4t + 30

Combining like terms gives us:

140 = 14t

Dividing both sides by 14 gives us:

t = 10

Now we can use Equation 1 to solve for o:

10 + o = 17

o = 7

So the original number is 10t + o = 10(10) + 7 = 107.

To prove the identity for any real number x and for all numbers n > 1:

x^n - 1 = (x - 1)(x^n-1 + x^n-2 + ... + x^(n-r) + ... + x + 1)

We will use mathematical induction to prove this identity.

Step 1: Base Case

Let n = 2:

x^2 - 1 = (x - 1)(x + 1)

x^2 - 1 = x^2 - 1

The base case holds true.

Step 2: Inductive Hypothesis

Assume the identity holds for some arbitrary k > 1, i.e.,

x^k - 1 = (x - 1)(x^k-1 + x^k-2 + ... + x^(k-r) + ... + x + 1)

Step 3: Inductive Step

We need to prove the identity holds for k+1, i.e.,

x^(k+1) - 1 = (x - 1)(x^(k+1)-1 + x^(k+1)-2 + ... + x^(k+1-r) + ... + x + 1)

Starting with the left-hand side (LHS):

x^(k+1) - 1 = x^k * x - 1 = x^k * x - x + x - 1 = (x^k - 1)x + (x - 1)

Now, let's focus on the right-hand side (RHS):

(x - 1)(x^(k+1)-1 + x^(k+1)-2 + ... + x^(k+1-r) + ... + x + 1)

Expanding the product:

= x * (x^(k+1)-1 + x^(k+1)-2 + ... + x^(k+1-r) + ... + x + 1) - (x^(k+1)-1 + x^(k+1)-2 + ... + x^(k+1-r) + ... + x + 1)

= x^(k+1) + x^k + ... + x^2 + x - (x^(k+1)-1 + x^(k+1)-2 + ... + x^(k+1-r) + ... + x + 1)

= x^(k+1) - x^(k+1) + x^k - x^(k+1-1) + x^(k-1) - x^(k+1-2) + ... + x^2 - x^(k+1-(k-1)) + x - x^(k+1-k) - 1

= x^k + x^(k-1) + ... + x^2 + x + 1

Comparing the LHS and RHS, we see that they are equal.

Step 4: Conclusion

The identity holds for n = k+1 if it holds for n = k, and it holds for n = 2 (base case). Therefore, by mathematical induction, the identity is proven for all numbers n > 1 and any real number x.

a. 2n² - 3n = θ(n²) (Both upper and lower bounds are n²).

b. n³ ≠ O(n²) (There is no upper bound).

To find the upper bound, lower bound, and tight bound ranges for the functions F(n) = 10n² + 4n + 2 and G(n) = n²/11, we need to determine their asymptotic behavior.

1. Upper Bound (Big O):

For F(n) = 10n² + 4n + 2, the highest-order term is 10n². Ignoring the lower-order terms and constants, we can say that F(n) is bounded above by O(n²). This means that there exists a constant c and a value n₀ such that F(n) ≤ cn² for all n ≥ n₀.

For G(n) = n²/11, the highest-order term is n². Ignoring the constant factor and lower-order terms, we can say that G(n) is also bounded above by O(n²).

2. Lower Bound (Big Omega):

For F(n) = 10n² + 4n + 2, the lowest-order term is 10n². Ignoring the higher-order terms and constants, we can say that F(n) is bounded below by Ω(n²). This means that there exists a constant c and a value n₀ such that F(n) ≥ cn² for all n ≥ n₀.

For G(n) = n²/11, the lowest-order term is n². Ignoring the constant factor and higher-order terms, we can say that G(n) is also bounded below by Ω(n²).

3. Tight Bound (Big Theta):

For F(n) = 10n² + 4n + 2, and G(n) = n^2/11, both functions have the same highest-order term of n². Therefore, we can say that F(n) and G(n) have the same tight bound range of Θ(n²). This means that there exist positive constants c₁, c₂, and a value n₀ such that c₁n² ≤ F(n) ≤ c₂n² for all n ≥ n₀.

In summary:

- F(n) = 10n² + 4n + 2 has an upper bound of O(n²), a lower bound of Ω(n²), and a tight bound of Θ(n²).

- G(n) = n²/11 has an upper bound of O(n²), a lower bound of Ω(n²), and a tight bound of Θ(n²).

Now let's move on to proving the given statements:

a. To prove that 2n² - 3n = θ(n²), we need to show both the upper bound and lower bound.

- Upper Bound (Big O):

For 2n² - 3n, the highest-order term is 2n². Ignoring the lower-order terms and constants, we can say that 2n² - 3n is bounded above by O(n²). This means there exists a constant c and a value n₀ such that 2n² - 3n ≤ cn² for all n ≥ n₀.

- Lower Bound (Big Omega):

For 2n² - 3n, the highest-order term is 2n². Ignoring the lower-order terms and constants, we can say that 2n² - 3n is bounded below by Ω(n²). This means there exists a constant c and a value n₀ such that 2n² - 3n ≥ cn² for all n ≥ n₀.

Since we have shown both the upper and lower bounds to be n², we can conclude that 2n² - 3n = θ(n²).

b. To prove that n³ ≠ O(n²), we need to show that there is no upper bound.

Assuming n³ = O(n²), this would mean that there exists a constant c and a value n₀ such that n³ ≤ cn² for all n ≥ n₀.

However, this statement is not true because as n approaches infinity, n³ grows faster than cn² for any constant c. Therefore, n³ is not bounded above by O(n²), and we can conclude that n³ ≠ O(n²).

(a) The equation of the plane passing through the points A(2, -1, 3), B(1, 0, -4), and C(2, 2, 5) is -5x - 2y - 3z + 17 = 0. (b) The parametric equation of the line passing through A(2, -1, 3) and B(1, 0, -4) is x = 2 - t, y = -1 + t, z = 3 - 7t, where t is a parameter.

(a) To find an equation of the plane passing through the points A(2, -1, 3), B(1, 0, -4), and C(2, 2, 5), we can use the cross product of two vectors in the plane.

Let's find two vectors in the plane: AB and AC.

Vector AB = B - A

= (1 - 2, 0 - (-1), -4 - 3)

= (-1, 1, -7)

Vector AC = C - A

= (2 - 2, 2 - (-1), 5 - 3)

= (0, 3, 2)

Next, we find the cross product of AB and AC:

N = AB x AC

= (1, 1, -7) x (0, 3, 2)

N = (-5, -2, -3)

The equation of the plane can be written as:

-5x - 2y - 3z + D = 0

To find D, we substitute one of the points (let's use point A) into the equation:

-5(2) - 2(-1) - 3(3) + D = 0

-10 + 2 - 9 + D = 0

-17 + D = 0

D = 17

So the equation of the plane passing through the points A, B, and C is: -5x - 2y - 3z + 17 = 0.

(b) To find the parametric equation of the line passing through points A(2, -1, 3) and B(1, 0, -4), we can use the vector form of the line equation.

The direction vector of the line is given by the difference between the coordinates of the two points:

Direction vector AB = B - A

= (1 - 2, 0 - (-1), -4 - 3)

= (-1, 1, -7)

The parametric equation of the line passing through A and B is:

x = 2 - t

y = -1 + t

z = 3 - 7t

where t is a parameter that can take any real value.

C(x) = 4x + 10

Revenue function is:

R(x) = -2x² + 44x

Profit function is the difference between Revenue and Cost functions.

Therefore, Profit function is given by:

P(x) = R(x) - C(x)

P(x) = -2x² + 44x - (4x + 10)

P(x) = -2x² + 40x - 10

In order to find the number of leashes which need to be sold to maximize the profit, we need to find the vertex of the parabola of the Profit function.

Therefore, the vertex is: `x = (-b) / 2a`where a = -2 and b = 40.

Putting the values of a and b, we get:

x = (-40) / 2(-2) = 10

Thus, 10 designer dog leashes need to be sold to maximize the profit.

To find the maximum profit, we need to put the value of x in the profit function:

P(x) = -2x² + 40x - 10

P(10) = -2(10)² + 40(10) - 10

= 390

The maximum profit is $390.

To find the price to charge per leash to maximize profit, we need to divide the maximum profit by the number of leashes sold:

Price per leash = 390 / 10

Answer:

the side is 20.4

Step-by-step explanation:

We have proved that if a^k ∈ H and gcd(n, k) = 1, then a ∈ H. To prove that a ∈ H, we need to show that a is an element of the subgroup H, given that H ≤ G and a has finite order n.

Let's start by using the given information:

Since a has finite order n, it means that a^n = e (the identity element of G).

Now, let's assume that a^k ∈ H, where k is a positive integer, and gcd(n, k) = 1 (which means that n and k are relatively prime).

By Bézout's identity, since gcd(n, k) = 1, there exist integers m and h such that mn + hk = 1.

Now, let's consider the element a^mn+hk:

a^mn+hk = (a^n)^m * a^hk

Since a^n = e, this simplifies to:

a^mn+hk = e^m * a^hk = a^hk

Since a^k ∈ H and H is a subgroup, a^hk must also be in H.

Therefore, we have shown that a^hk ∈ H, where mn + hk = 1 and gcd(n, k) = 1.

Now, since H is a subgroup and a^hk ∈ H, it follows that a ∈ H.

Hence, we have proved that if a^k ∈ H and gcd(n, k) = 1, then a ∈ H.

The Theorem states that let k be any natural number. Then there is a natural number n that will be much larger than k such that no natural number greater than 1 and less than k will divide n. The fundamental theorem of arithmetic states that every natural number greater than 1 is either a prime number itself or can be factored as a product of prime numbers in a unique way.

This theorem gives the existence of the prime numbers, which are the building blocks of number theory. Euclid's proof of the existence of an infinite number of prime numbers is a classic example of the use of contradiction in mathematics.The theorem can be proved by contradiction.

Suppose the theorem is false and that there is a smallest natural number k for which there is no natural number n such that no natural number less than k and greater than 1 divides n. If this is the case, then there must be some natural number m such that m is the product of primes p1, p2, …, pt, where p1 < p2 < … < pt.

Then, by assumption, there is no natural number less than k and greater than 1 that divides m. So, in particular, p1 > k, which means that k is not the smallest natural number for which the theorem fails. This contradicts the assumption that there is a smallest natural number k for which the theorem fails.

In conclusion, Theorem states that let k be any natural number. Then there is a natural number n that will be much larger than k such that no natural number greater than 1 and less than k will divide n. This theorem gives the existence of the prime numbers, which are the building blocks of number theory.

The pressure (p) at the bottom of a swimming pool varies directly as the depth (d).This is a direct proportion because as the depth of the pool increases, the pressure at the bottom also increases in proportion to the depth.

P α dwhere p is the pressure at the bottom of the pool and d is the depth of the pool.To find the constant of proportionality, we need to use the given information that the pressure is 50 kPa when the depth is 10 m. We can then use this information to write an equation that relates p and d:P α d ⇒ P

In summary, the algorithm has a time complexity of Θ(n log₃(n)) when x is greater than 2, and a constant time complexity of Θ(1) when x is less than or equal to 2.

The given recurrence relation for the algorithm's running time T(n) is:

T(n) = 2T(3n) + Θ(n) if x > 2

T(n) = Θ(1) if x ≤ 2

To analyze the time complexity of the algorithm, we need to examine the behavior of the recurrence relation.

If x > 2, the recurrence relation states that T(n) is twice the running time of the algorithm on a problem of size 3n, plus a term proportional to n. This indicates a recursive subdivision of the problem into smaller subproblems.

If x ≤ 2, the recurrence relation states that T(n) is constant, indicating that the algorithm has a base case and does not further divide the problem.

To determine the overall time complexity, we need to consider the values of x and the impact on the recursion depth.

If x > 2, the problem size decreases by a factor of 3 with each recursive step. The number of recursive steps until the base case is reached can be determined by solving the equation:

n = (3^k)n₀

where k is the number of recursive steps and n₀ is the initial problem size. Solving for k, we get:

k = log₃(n/n₀)

Therefore, the recursion depth for the case x > 2 is logarithmic in the problem size.

Combining these observations, we can conclude that the time complexity of the algorithm is:

If x > 2: T(n) = Θ(n log₃(n))

If x ≤ 2: T(n) = Θ(1)

Yes, it is advantageous to switch from door #1 to door #2. The conditional probability that the car is behind door #2 given the relevant information that Monty opened door #3 and revealed a goat is 2/3.

Here's how to arrive at this solution:

First, let's define the events: C1, C2, and C3 are the events that the car is behind door #1, #2, or #3, respectively; A2 and A3 are the events that Monty opens door #2 or #3, respectively.

Let's assume that the contestant chooses door #1, and the car is behind door #2, so C2 is true.

Then Monty is forced to open door #3, revealing a goat. The probability of this happening is P(A3|C2) = 1. Since Monty cannot open the door with the car behind it, he is forced to open the door with the goat behind it, so

P(A2|C2) = 0.

Therefore, by Bayes' theorem,

P(C2|A3) = [P(A3|C2)P(C2)] / [P(A3|C1)P(C1) + P(A3|C2)P(C2) + P(A3|C3)P(C3)]

= (1 * 1/3) / (1/2 * 1/3 + 1 * 1/3 + 0 * 1/3)

= 2/3

So, the conditional probability that the car is behind door #2 given the information that Monty opens door #3 and reveals a goat is 2/3. Therefore, it is advantageous to switch from door #1 to door #2.

If the current price is 11 dollars and the price is increased by 1%, then the total revenue will increase.

Given that the current price is 11 dollars.

Let's assume that the quantity demanded is constant at q dollars.

Since price p is increased by 1%, the new price would be: p = 1.01 × 11 = 11.11 dollars.

The new revenue would be: R = q × 11.11.

The total revenue has increased because the new price is greater than the initial price.

Price elasticity of demand is defined as the percentage change in quantity demanded that is caused by a 1% change in price.

A unitary elastic demand happens when a 1% change in price produces an equal percentage change in quantity demanded.

The total revenue remains the same when price is unit elastic.If the price is increased by 1%, then the total revenue will increase when the price elasticity of demand is inelastic, and it will decrease when the price elasticity of demand is elastic.

If the percentage change in quantity demanded is less than the percentage change in price, the demand is inelastic. If the percentage change in quantity demanded is more than the percentage change in price, the demand is elastic.

When the price increases by 1%, the new price would be p = 1.01 × 11 = 11.11 dollars.

Assuming the quantity demanded remains constant at q dollars, the new revenue would be R = q × 11.11. Therefore, the total revenue will increase because the new price is greater than the initial price.

The point-slope form of the line that passes through the given point with the given slope is explained below:The formula for the point-slope form of a linear equation is:$$y-y_1 = m(x-x_1)$$where (x1,y1) is a point on the line and m is the slope of the line.

Since we have a four-dimensional point with the given coordinates (4, 8, 1, 8), we'll assume that the first three coordinates (x1, y1, z1) are our point, and the last coordinate is a fourth dimension we don't need for a line in three-dimensional space. So, the given point is (4, 8, 1), and the slope is m=2.8.To find the equation of the line, we can plug in the given values into the point-slope form as follows:$$y - 8 = 2.8(x - 4)$$

This is the point-slope form of the line that passes through the point (4, 8, 1) with slope m=2.8. The equation can be simplified by distributing 2.8 on the right-hand side to get:$$y - 8 = 2.8x - 11.2$$Finally, we can move -8 to the right-hand side of the equation and get the slope-intercept form as:$$y = 2.8x - 3.2$$This is the equation of the line in slope-intercept form, where the slope is 2.8 and the y-intercept is -3.2.

The probability that materials to the construction site will not be delivered on schedule is 0.435. And the probability that it will be caused by train transportation is 0.3448 (rounded to four decimal places).

Given: 73% of the materials are transported by trucks and the remaining 27% by trains.

The probability of on-time delivery by trucks is 0.70, whereas the corresponding probability by trains is 0.85.

To find: The probability that materials to the construction site will not be delivered on schedule.

Solution: Let A be the event that materials are transported by truck and B be the event that materials are transported by train. Since 73% of the materials are transported by trucks, then P(A) = 0.73 and since 27% of the materials are transported by trains, then P(B) = 0.27

Also, the probability of on-time delivery by trucks is 0.70, then

P(On time delivery by trucks) = 0.70

And the probability of on-time delivery by trains is 0.85, then P(On time delivery by trains) = 0.85

The probability that materials to the construction site will not be delivered on schedule

P(Delayed delivery) = P(not on time delivery)

P(Delayed delivery by trucks) = P(not on time delivery by trucks) = 1 - P(on time delivery by trucks) = 1 - 0.70 = 0.30

P(Delayed delivery by trains) = P(not on time delivery by trains) = 1 - P(on time delivery by trains) = 1 - 0.85 = 0.15

The probability that materials to the construction site will not be delivered on schedule

P(Delayed delivery) = P(Delayed delivery by trucks) ⋃ P(Delayed delivery by trains) = P(Delayed delivery by trucks) + P(Delayed delivery by trains) - P(Delayed delivery by trucks) ⋂ P(Delayed delivery by trains)P(Delayed delivery) = (0.3) + (0.15) - (0.3) x (0.15)

P(Delayed delivery) = 0.435

Venn diagram: Probability that it will be caused by train transportation = P(Delayed delivery by trains) / P(Delayed delivery)

Probability that it will be caused by train transportation = 0.15 / 0.435

Probability that it will be caused by train transportation = 0.3448 (rounded to four decimal places)

a)

The value of the term deposit after 4.5 years is $68,950.53.

Calculation of the value of the term deposit after 4.5 years:
The compound interest formula is: $A=P(1+r)^n

Where:

P is the initial amount

r is the interest rate per compounding period,

n is the number of compounding periods

A is the final amount.

Given:

P=$45000,

r=8.8% per annum, and

n = 4.5 years (annually compounded).

Now substituting the given values in the formula we get,

A=P(1+r)^n

A=45000(1+0.088)^{4.5}

A=45000(1.088)^{4.5}

A=45000(1.532234)

A=68,950.53

Therefore, the value of the term deposit after 4.5 years is $68,950.53.

b)

The interest earned is $23950.53

Interest is the difference between the final amount and the initial amount. The initial amount is $45000 and the final amount is $68,950.53.

Thus, Interest earned = final amount - initial amount

Interest earned = $68,950.53 - $45000

Interest earned = $23950.53

Therefore, the interest earned is $23950.53.
