Step-by-step explanation:

The standard deviation eliminates the drawback of having the measure of dispersion in squared units rather than in the original measurement units. This is because the standard deviation is calculated by taking the square root of the variance, which is in squared units. So, the standard deviation gives a measure of dispersion in the same units as the original measurements.

Scattering alludes to the spread or changeability of information focuses in a dataset.

Variation could be a degree of scattering, but it is calculated by squaring the contrasts between each information point and the cruel. As a result, the variation is communicated in squared units, which may not be straightforwardly interpretable or significant within the setting of the initial estimation units.

The standard deviation, on the other hand, is the square root of the change. By taking the square root, it brings the degree of dispersion back to the initial estimation units, making it more effortlessly interpretable and comparable to the first information.

The area of the rug is 1,440 square inches and the sum of partial product is always equal to the area, 1440 square inches.

The area of the rug using the formula:

length x width = area.

The area of the rug is:

32 inches x 45 inches = 1440 square inches.

Refer figure for Erin and Frannie's design. Consider Erin's design

green = 30×5 = 150

red = 2×5 = 10

blue = 2×40 = 80

yellow = 30×40 = 1200

total area = green + red + blue + yellow

= 150 + 10 + 80 + 1200

= 1,440

Now consider Frannie's design

red = 5×1 = 5

blue = 35×1 = 35

green = 5×30 = 150

yellow = 35×30 = 1050

total area = 4red + 2blue + 2green + yellow

= 4×5 + 2×35 + 2×150 + 1050

= 20 + 70 + 300 + 1050

= 1,440

Answer:

6cups

Step-by-step explanation:

Given the equation

1 1/2 + 1/4c=3

We are to find the value of c

3/2 + c/4 = 3

c/4 = 3 - 3/2

c/4 = (6-3)/2

c/4 =3/2

Cross multiply

2c = 3×4

2c = 12

c =6

Hence he adds 6cups of flour

To determine the value of c that allows a function to serve as a probability distribution for a discrete random variable X, we need to ensure that the function satisfies two properties: non-negativity and the sum of probabilities equals 1.

(a) For the function f(x) = \(c(x^2 + 4)\), we need to determine the value of c. To satisfy the properties of a probability distribution, we must ensure that f(x) is non-negative for all possible values of x and that the sum of probabilities equals 1.

The possible values of x are 0, 1, 2, and 3. We can evaluate f(x) for each value of x:

f(0) = c(0^2 + 4) = 4c

f(1) = c(1^2 + 4) = 5c

f(2) = c(2^2 + 4) = 8c

f(3) = c(3^2 + 4) = 13c

For f(x) to serve as a probability distribution, all values of f(x) must be non-negative. Therefore, we need to ensure that 4c, 5c, 8c, and 13c are all non-negative. This implies that c must be greater than or equal to 0.

f(0) + f(1) + f(2) + f(3) = 4c + 5c + 8c + 13c = 30c

For the sum of probabilities to equal 1, we must have:

30c = 1

Solving for c, we find c = 1/30.

(b) For the function f(x) = c^(2x)^(3(3-x)), we can follow a similar approach. We need to ensure that f(x) is non-negative for all possible values of x and that the sum of probabilities equals 1.

The possible values of x are 0, 1, and 2. Evaluating f(x) for each value:

f(0) = \(c^(2(0))^(3(3-0)) = c^0 = 1\)

f(1) = \(c^(2(1))^(3(3-1)) = c^2^6 = c^12\)

f(2) =\(c^(2(2))^(3(3-2)) = c^4^3 = c^12\)

To satisfy the non-negativity property, we need to ensure that c^12 is non-negative, which implies that c must be greater than or equal to 0.

To satisfy the sum of probabilities equaling 1, we sum up the probabilities:

\(f(0) + f(1) + f(2) = 1 + c^12 + c^12\)

However, since c must be greater than or equal to 0, we conclude that there is no valid value of c that allows the function f(x) = c^(2x)^(3(3-x)) to serve as a probability distribution.

The inequality given by (x/3) + 5 ≥ 1/6 has the solution x ≥ -29/2 or [-29/2 , +∞).

Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.

To solve an inequality is to find the values of x such that when we substitute that number for x we have a true statement.

Given the inequality (x/3) + 5 ≥ 1/6, subtract 5 from both sides.

(x/3) + 5 - 5 ≥ 1/6 - 5

x/3 ≥ -29/6

Multiply both sides by 3.

3(x/3) ≥ 3(-29/6)

x ≥ -29/2

To check, let x = -29/2

x = -29/2 ≥ -29/2

Substitute this value to the inequality.

(x/3) + 5 ≥ 1/6

(-29/2)/3 + 5 ≥ 1/6

1/6 ≥ 1/6

let x = -14,

x = -14 ≥ -29/2

To determine if the new fertilizer is effective, the farmer can use hypothesis testing, specifically a one-sample t-test. This test compares the mean yield of the corn crop using the new fertilizer to the historical mean yield of the corn crop using the old fertilizer.

1. Formulate hypotheses: Set up a null hypothesis (H0) stating that the fertilizer has no effect on yield, and an alternative hypothesis (H1) stating that the fertilizer increases yield.

2. Collect data: The farmer should divide his field into two sections - one with the new fertilizer and one without. He should then measure the corn yield from each section.

3. Determine the test statistic: Calculate the mean yield for each section and find the difference between them.

4. Set a significance level: Choose an acceptable level of Type I error (commonly 5%, represented as α = 0.05).

5. Calculate p-value: Using the appropriate statistical test (e.g., t-test or ANOVA), determine the probability of observing the calculated test statistic or a more extreme value, assuming the null hypothesis is true.

6. Compare p-value to α: If the p-value is less than α, reject the null hypothesis in favor of the alternative hypothesis, indicating that the fertilizer was effective in increasing corn crop yield.

(a) the parameterization of the surface becomes S(u, v) = (u, v, 1 - u - v) with 0 < u, v < 1.

(b) the parameterization of the surface becomes S(r, θ) = (r cos(θ), r sin(θ), 1 - r cos(θ) - r sin(θ)) with 0 ≤ r ≤ 2 and 0 ≤ θ < 2π.

(c)  the portion of the cone z = x² + y² can be parameterized as S(u, v) = (√vcos(u), √vsin(u), v) with 0 ≤ u < 2π and v ≥ 0.

In this problem, we are asked to parameterize certain surfaces. Let's examine each case individually:

a) The portion of the plane x + y + z = 1 with 0 < x, y < 1:

To parameterize this portion of the plane, we can use a parameterization involving two variables. Let's denote the variables as u and v. We can set u = x and v = y, and then express z in terms of u and v as z = 1 - u - v. Thus, the parameterization of the surface becomes S(u, v) = (u, v, 1 - u - v) with 0 < u, v < 1.

b) The portion of the plane x + y + z = 1 inside the cylinder x² + y² = 4:

To parameterize this portion of the plane, we can utilize cylindrical coordinates. Let's denote the variables as r, θ, and z. We can express x and y in terms of r and θ as x = r cos(θ) and y = r sin(θ), and then express z in terms of r as z = 1 - x - y = 1 - r cos(θ) - r sin(θ).

Thus, the parameterization of the surface becomes S(r, θ) = (r cos(θ), r sin(θ), 1 - r cos(θ) - r sin(θ)) with 0 ≤ r ≤ 2 and 0 ≤ θ < 2π.

c) The portion of the cone z = x² + y²:

To parameterize this cone, we can use a parameterization involving two variables. Let's denote the variables as u and v. We can set u = θ (angle in the xy-plane) and v = z, and then express x and y in terms of u as x = √vcos(u) and y = √vsin(u). Thus, the parameterization of the surface becomes S(u, v) = (√vcos(u), √vsin(u), v) with 0 ≤ u < 2π and v ≥ 0.

In summary, a) the portion of the plane x + y + z = 1 with 0 < x, y < 1 can be parameterized as S(u, v) = (u, v, 1 - u - v) with 0 < u, v < 1. b) the portion of the plane x + y + z = 1 inside the cylinder x² + y² = 4 can be parameterized as S(r, θ) = (rcos(θ), rsin(θ), 1 - rcos(θ) - rsin(θ)) with 0 ≤ r ≤ 2 and 0 ≤ θ < 2π. c) the portion of the cone z = x² + y² can be parameterized as S(u, v) = (√vcos(u), √vsin(u), v) with 0 ≤ u < 2π and v ≥ 0.
