If the consumption function C=350+0.90∗Yd, the savings function S = 0.1Yd - 350, the level of savings when Yd= $3500 is 0, the break-even level of Yd is $875, the slope indicates the proportion of disposable income that is consumed, and the graph of the savings function is shown below.

a) The formula to find the savings is as follows: S = Yd - C = Yd - (350 + 0.90Yd) = 0.1Yd - 350. Therefore, the saving function is S = 0.1Yd - 350.

b) When Yd = $3,500, S = 0.1(3,500) - 350= $0. Therefore, the level of savings when Yd=$3,500 is $0.

c) The break-even level of Yd is the level of disposable income where the level of consumption equals the level of savings. So, 0.1Yd - 350 = 350+0.90∗Yd ⇒0.80Yd = 700 ⇒Yd = $875. Hence, the break-even level of Yd is $875.

d) The slope of the consumption function measures the responsiveness of consumption to a change in disposable income. The consumption function's slope above is 0.90, which means that for every one unit increase in disposable income, consumption increases by 0.90 units.

e) The graph for the saving function S = 0.10Yd - 350 will be a straight line with a slope of 0.10 and a y-intercept of -350. The x-axis will be the disposable income, and the y-axis will be savings. Plotting the points (0, -350) and (3500, 0), we can plot the graph as shown below.

1) A conversion factor is a ratio that relates two different units of measurement and is used to convert between them.

2) The conversion factor for s/min (seconds per minute) is 60 s/min. This means that there are 60 seconds in one minute.

3) To determine the conversion factor for min²/s² (minutes squared per second squared), we need to analyze Equation 2.2-3. Since the units of the left-hand side of the equation are in minutes squared per second squared, we can equate it to the right-hand side of the equation and derive the conversion factor.

Equation 2.2-3: 1 min²/s² = (60 s/min)² / (1 s)²

Simplifying the equation:

1 min²/s² = (60² s² / s²)

Therefore, the conversion factor for min²/s² is 3600.

4) The conversion factor for m³/cm³ (cubic meters per cubic centimeter) can be derived by analyzing the relationship between the two units. Since there are 100 centimeters in 1 meter, the conversion factor is determined by cubing this ratio.

Conversion factor for m³/cm³ = (100 cm / 1 m)³

Simplifying the equation:

Conversion factor for m³/cm³ = (100³ cm³ / 1³ m³)

The probability of obtaining a reading between 1.231∘C and 2.176∘C is 0.0947, calculated using the z-score formula. The z-score represents the number of standard deviations that a given value (x) is above or below the mean (μ), and can be calculated as Z = (x - μ) / σ. The given values are 1.231 and 2.176, respectively.

Given, the readings at freezing on a batch of thermometers are normally distributed with a mean of 0∘C and a standard deviation of 1.00∘C and we have to find the probability of obtaining a reading between 1.231∘C and 2.176∘C.

P(1.231< reading <2.176)Z1

= (1.231-0)/1.00

= 1.231Z2

= (2.176-0)/1.00

= 2.176

The z-values for the given values are 1.231 and 2.176. Using the z-score formula, the corresponding probabilities can be calculated.

P(Z < 1.231) = 0.8911

P(Z < 2.176) = 0.9858

Using the probabilities, the required probability can be calculated:

P(1.231< reading <2.176) = P(Z < 2.176) - P(Z < 1.231) = 0.9858 - 0.8911 = 0.0947

Therefore, the probability of obtaining a reading between 1.231∘C and 2.176∘C is 0.0947 (approximately).Note: Here, Z represents the z-score, which is also known as the standard score.

It is the number of standard deviations that the given value (x) is above or below the mean (μ). It can be calculated as Z = (x - μ) / σ, where x is the given value, μ is the mean, and σ is the standard deviation.

Cov(Xn+1/Xn, Xn/Xn-1) = E[(Xn+1/Xn)Xn/Xn-1] - E(Xn+1/Xn)E(Xn/Xn-1) - E(Xn+1/Xn)E(Xn/Xn-1) + E(Xn+1/Xn)E(Xn/Xn-1).

Using the fact that E(Xn+1/Xn)

To prove that E(Xn+1/Xn) = 1, we can use the definition of a martingale. A martingale is a sequence of random variables {Xn, n ≥ 0} such that for any n ≥ 0, E(|Xn|) < ∞ and E(Xn+1|X1, X2, ..., Xn) = Xn.

Given that {(Xn, Bn), n ≥ 0} is a martingale, we have the property that E(Xn+1|X1, X2, ..., Xn) = Xn.

Now let's consider the ratio Xn+1/Xn. We want to prove that E(Xn+1/Xn) = 1.

Using the law of iterated expectations, we can write:

E(Xn+1/Xn) = E(E(Xn+1/Xn|X1, X2, ..., Xn)).

Since Xn+1 is independent of X1, X2, ..., Xn, we can simplify this expression to:

E(Xn+1/Xn) = E(E(Xn+1/Xn)).

Since E(Xn+1/Xn) is a constant, we can take it out of the inner expectation:

E(Xn+1/Xn) = E(Xn+1)E(1/Xn).

Since Xn+1/Xn ∈ L1, we know that E(1/Xn) is finite.

Therefore, E(Xn+1/Xn) = E(Xn+1)E(1/Xn) = E(Xn+1)/E(Xn).

But we know that E(Xn+1|X1, X2, ..., Xn) = Xn, so E(Xn+1) = Xn.

Substituting this into the previous equation, we get:

E(Xn+1/Xn) = Xn/E(Xn).

Since E(Xn) ≠ 0 (since we assume Xn+1/Xn ∈ L1), we have:

E(Xn+1/Xn) = 1.

This proves that E(Xn+1/Xn) = 1.

To show that Xn+1/Xn and Xn/Xn-1 are uncorrelated for any n ≥ 1, we need to show that their covariance is zero.

Cov(Xn+1/Xn, Xn/Xn-1) = E[(Xn+1/Xn - E(Xn+1/Xn))(Xn/Xn-1 - E(Xn/Xn-1))].

Using the linearity of expectations, we can expand this expression:

Cov(Xn+1/Xn, Xn/Xn-1) = E[(Xn+1/Xn)(Xn/Xn-1)] - E[(Xn+1/Xn)E(Xn/Xn-1)] - E[E(Xn+1/Xn)(Xn/Xn-1)] + E[E(Xn+1/Xn)E(Xn/Xn-1)].

Since Xn+1/Xn and Xn/Xn-1 are functions of independent random variables, we can write:

Cov(Xn+1/Xn, Xn/Xn-1) = E[(Xn+1/Xn)Xn/Xn-1] - E(Xn+1/Xn)E(Xn/Xn-1) - E(Xn+1/Xn)E(Xn/Xn-1) + E(Xn+1/Xn)E(Xn/Xn-1).

The following is the given data for the brand of refrigerator.

Let "x" be the unit price of the refrigerator in dollars, and "y" be the number of refrigerators produced.

Suppose that the producers of a certain brand of the refrigerator make 1000 refrigerators available when the unit price is $410.

This implies that:

y = 1000x = 410

When the unit price of the refrigerator is $450, 5000 refrigerators will be marketed.

This implies that:

y = 5000x = 450

To find the equation of the line that represents the relationship between price and quantity, we need to solve the system of equations for x and y:

1000x = 410

5000x = 450

We can solve the first equation for x as follows:

x = 410/1000 = 0.41

For the second equation, we can solve for x as follows:

x = 450/5000 = 0.09

The slope of the line that represents the relationship between price and quantity is given by:

m = (y2 - y1)/(x2 - x1)

Where (x1, y1) = (0.41, 1000) and (x2, y2) = (0.09, 5000)

m = (5000 - 1000)/(0.09 - 0.41) = -10000

Therefore, the equation of the line that represents the relationship between price and quantity is:

y - y1 = m(x - x1)

Substituting m, x1, and y1 into the equation, we get:

y - 1000 = -10000(x - 0.41)

Simplifying the equation:

y - 1000 = -10000x + 4100

y = -10000x + 5100

This is the equation of the line that represents the relationship between price and quantity.

Each rectangle has four right angles. This is true since rectangles have four right angles.

True. In Euclidean geometry, a rectangle is defined as a quadrilateral with four right angles, meaning each angle measures 90 degrees. Additionally, a rectangle is characterized by having opposite sides that are parallel and congruent, meaning they have the same length. Therefore, each side of a rectangle has the same length as the adjacent side, resulting in four sides with equal length. Consequently, both statements "Each rectangle has four sides with the same length" and "Each rectangle has four right angles" are true for all rectangles in Euclidean geometry.

The correct answer is O e^t^2(trA).

Given F(t) = det(e^t), we need to determine the expression for F(t). To do this, let's consider the matrix A:

A = e^t

The determinant of A can be written as det(A) = det(e^t). Since the matrix A is a 2x2 real matrix, we can write it in terms of its elements:

A = [[a, b], [c, d]]

where a, b, c, and d are real numbers.

Using the formula for the determinant of a 2x2 matrix, we have:

det(A) = ad - bc

Now, substituting the matrix A = e^t into the determinant expression, we get:

det(e^t) = e^t * e^t - 0 * 0

The function that describes the fare per kilometer in a jeepney ride is:

$$f(x)=\begin{cases}9, & x \in [0,4) \\\ 1.40(x-4)+9, & x \in [4,9]\end{cases}$$

Here, x is the number of kilometers of the jeepney ride.

The first 4 kilometers cost Php 9 per kilometer. Thus, the fare for the first 4 kilometers is fixed at Php 9 per kilometer. For the distance from 4 to 9 kilometers, the cost is Php 1.40 per kilometer. So, the fare per kilometer in this interval is $1.40(x-4)$.

However, we have to add Php 9 since the first 4 kilometers already cost Php 9. Therefore, the fare function for this interval is $1.40(x-4)+9$.

To determine the domain of this function, we have to consider only the values of x that fall between 0 and 9 kilometers since the jeepney's route is at most 9 kilometers. Thus, the domain of the function is:

(b) The results from part (a) suggest that it is highly likely, with a probability of approximately 0.9998, that at least 976 out of the 1332 randomly selected voters actually voted in the recent presidential election.

To find the probability that among 1332 randomly selected voters, at least 976 actually did vote, we can use the binomial distribution.

Given:

Total sample size (n) = 1332

Probability of success (p) = 0.71 (71% of eligible voters actually voted)

To find the probability of at least 976 people actually voting, we need to calculate the cumulative probability from 976 to the maximum possible number of voters (1332).

Using a binomial distribution calculator or software, we can find the cumulative probability:

P(X ≥ 976) = 1 - P(X < 976)

Using the binomial distribution formula:

P(X < 976) = Σ (nCx) * p^x * (1-p)^(n-x)

where Σ represents the sum from x = 0 to 975.

Calculating the cumulative probability, we find:

P(X ≥ 976) ≈ 0.9998 (rounded to four decimal places)

i. To find the probability that there are more than 4 bacteria in 1 ml of water, we can use the Poisson probability mass function:

P(X > 4) = 1 - P(X ≤ 4)

where X is the number of bacteria in 1 ml of water.

Using the Poisson distribution with mean 2.4, we have:

Therefore, the probability that there are less than 4 bacteria in 0.5 ml of water is approximately 0.4118.

Answer: 1

Step-by-step explanation:

The answer to the expression 1+1+2-3 is 1.

starting from the left, we add 1 and 1 to get 2, then add 2 to get 4, and finally subtract 3 to get 1. So the solution is 1.

Therefore, 1+1+2-3 = 1.

The coordinates of the polynomial p(x) = -32 - 24x - 40x^2 relative to the basis B = {2 + 2x^2, 10 + 4x + 10x^2 - 14 - 8x - 16x^2} are [p(x)]_B = [-31, 3].

To find the coordinates of the polynomial p(x) = -32 - 24x - 40x^2 relative to the basis B = {2 + 2x^2, 10 + 4x + 10x^2 - 14 - 8x - 16x^2} for P₃, we need to express p(x) as a linear combination of the basis vectors.

We set up the equation:

p(x) = c₁(2 + 2x²) + c₂(10 + 4x + 10x² - 14 - 8x - 16x²)

Expanding and simplifying:

p(x) = 2c₁ + 2c₂x² + 10c₂ + 4c₂x + 10c₂x² - 14c₂ - 8c₂x - 16c₂x²

Now we equate the corresponding coefficients of the same powers of x on both sides of the equation:

-32 - 24x - 40x² = 2c₁ + 10c₂ + (-16c₂) x² + (4c₂ - 8c₂)x

We can now compare coefficients:

2c₁ + 10c₂ = -32

-16c₂ = -24

4c₂ - 8c₂ = -40

From the second equation, we find c₂ = 3. Substituting this value into the first and third equations:

2c₁ + 10(3) = -32

2c₁ + 30 = -32

2c₁ = -32 - 30

2c₁ = -62

c₁ = -31

Therefore, the coordinates of p(x) = -32 - 24x - 40x² relative to the basis B are [p(x)]_B = [-31, 3].

To find the difference quotient for the function f(x) = x - 5, we need to evaluate the expression (f(x + h) - f(x))/h, where h represents a small change in the x-value.

First, let's substitute f(x + h) and f(x) into the difference quotient expression:

(f(x + h) - f(x))/h = [(x + h) - 5 - (x - 5)]/h

Simplifying the numerator:

(f(x + h) - f(x))/h = [(x + h) - x + 5 - (-5)]/h

                     = [(x + h - x) + 10]/h

                     = (h + 10)/h

Now, we have the simplified difference quotient expression as (h + 10)/h.

This difference quotient represents the average rate of change of the function f(x) = x - 5 over a small interval of h. It indicates how much the function changes on average for each unit change in x over that interval.

Note that as h approaches 0, the difference quotient approaches a certain value, which is the derivative of the function f(x). In this case, since the function f(x) = x - 5 is a linear function with a constant slope of 1, the derivative is equal to 1.

So, the difference quotient (h + 10)/h represents the average rate of change of the function f(x) = x - 5, and as h approaches 0, it approaches the derivative of the function, which is 1.

Using the geometric distribution, the probability of meeting a native to the town among the next 5 people is [tex]0.034[/tex]

Firstly, we know that [tex]43\%[/tex] of the town's residents were born in the town, so the probability of meeting someone who is not a native to the town is [tex]0.57[/tex]

Using the geometric distribution formula, the probability of meeting the first non-native to the town among the next 5 people is:

[tex]P(X = 1) = (0.57)^1(0.43)[/tex]

≈[tex]0.245[/tex]

Similarly, the probability of meeting the second non-native to the town among the next 5 people is:

[tex]P(X = 2) = (0.57)^2(0.43)[/tex]

≈ [tex]0.132[/tex]

The probability of meeting the third non-native to the town among the next 5 people is:

[tex]P(X = 3) = (0.57)^3(0.43)[/tex]

≈ [tex]0.0712[/tex]

The probability of meeting the fourth non-native to the town among the next 5 people is:

The unit price you should charge to break even is $75 per shirt.

(a) Weekly profit as a function of the price per shirt:

In general, Profit = Revenue - CostThe revenue function is given as a product of price per unit and the quantity sold.

So, the revenue function is: R(x) = xq

where q = -60x + 7200

Putting the values in the equation we get,

R(x) = x(-60x + 7200)R(x)

= -60x^2 + 7200x

Profit = Revenue - CostProfit(x)

= R(x) - C(x)Profit(x)

= -60x^2 + 7200x - (-1800x + 283500)Profit(x)

= -60x^2 + 9000x - 283500

(b) To find the break-even price, we need to find the value of x that makes the profit equal to zero.

Profit(x) = 0-60x^2 + 9000x - 283500

= 0

Divide by -60x^2 + 9000x - 283500= 0x^2 - 150x + 4725

= 0

Factorizing the quadratic equation we get,

x(x - 150) + 4725 = 0or (x - 75)(x - 75)

The weekly profit as a function of the price per shirt x is 1740x - 276300. The unit price needed to break even is approximately $158.62.

To find the weekly profit as a function of the price per shirt x, we need to subtract the cost function C(x) from the demand function q(x). The profit function P(x) is given by:

P(x) = q(x) - C(x) = (-60x+7200) - (-1800x+283500) = 1740x - 276300

To determine the unit price needed to break even, we set P(x) equal to zero and solve for x:

0 = 1740x - 276300

1740x = 276300

x = 276300/1740

The graphs of f(x) = x² and g(x) = (x - 2)² + 1 are very similar. They both have the same shape, but the graph of g(x) is shifted down 1 unit. This can be seen by evaluating both functions at the same values of x. For example, f(0) = 0 and g(0) = 1, which shows that the graph of g(x) is 1 unit below the graph of f(x) at the point x = 0.

The function g(x) = (x - 2)² + 1 is a transformation of the function f(x) = x². The transformation is a translation down by 1 unit. This can be seen by expanding the square in the expression for g(x). We get:

g(x) = (x - 2)² + 1 = x² - 4x + 4 + 1 = x² - 4x + 5

The term +5 in the expression for g(x) shifts the graph down by 1 unit, since 5 is added to the output of the function for every value of x.

Therefore, the graph of the function g(x) = (x - 2)² + 1 is a translation of the graph f(x) = x² down by 1 unit.
