Answer:

The equation of a line in the form of y = mx + b, where m is the slope, x is the variable and b is the y-intercept.

Given a point and the slope, we can find the equation of the line that passes through that point. We know that the slope of the line is 0, so we can write the equation of the line as:

y = 0x + b

We also know that the line passes through the point (-3,-8), so we can substitute these values into the equation and solve for b, the y-intercept:

-8 = 0(-3) + b

-8 = 0 + b

b = -8

So the equation of the line that passes through the point (-3,-8) and has a slope of 0 is:

y = 0x - 8

This line is a horizontal line with y-intercept -8, which means that the line passes through the point (0,-8)

The value of the expression "true && !false" can be determined by evaluating each part separately and then combining the results.

1. The "!" symbol represents the logical NOT operator, which negates the value of the following expression. In this case, "false" is negated to "true".

2. The "&&" symbol represents the logical AND operator, which returns true only if both operands are true. Since the first operand is "true" and the second operand is "true" (as a result of the negation), the overall expression evaluates to "true".

Therefore, the value of the expression "true && !false" is "true".

Step-by-step explanation:

because you want to find the sum of the amount.

By calculating the cube root of 729, we find that x = 9. Therefore, the minimum height, width, and length required to build the tank are all 9m.

To calculate the minimum height, width, and length required to build the tank, we need to consider the volume of the tank. In this case, the volume of the tank is given as 729m³.

Since the tank is cubical, all sides are equal in length. Let's assume the length of each side is 'x'. Therefore, the volume of the tank can be calculated using the formula:

Volume = length × width × height

In this case, since all sides are equal, we can rewrite the formula as:

Volume = x × x × x

Given that the volume is 729m³, we can substitute this value into the formula:

729 = x × x × x

To solve for 'x', we need to find the cube root of 729. The cube root of a number is the value that, when multiplied by itself three times, gives the original number.

By calculating the cube root of 729, we find that x = 9.

Therefore, the minimum height, width, and length required to build the tank are all 9m.

When the measure of two angles add 90 degrees, then they are called complementary angles.

Answer:

Domain = [0, ∞).

Step-by-step explanation:

he profit, in dollars, when the company sells x shirts can be found using the function

\(f(x)=8x-40\)

For x=0,

\(f(0)=8(0)-40=-40\)

It means, if company sells 0 shirts, then company makes loss (because of negative sign) of $40.

For x=5,

\(f(5)=8(5)-40=0\)

It means, if company sells 5 shirts, then company makes profit of $0 means no loss no profit.

For x=10,

\(f(10)=8(10)-40=40\)

It means, if company sells 10 shirts, then company makes profit of $40.

Domain is the set of input values.

We know that number of shirts can not be negative, therefore the value of x is always greater than or equal to 0.

Domain = [0, ∞).

Therefore, the domain for the function is [0, ∞).

The given problem involves evaluating integrals with specific values. We are provided with the following information:

∫[6 to 2] x³ dx = 320

∫[6 to 2] x dx = 16

∫[6 to 2] dx = 4

To evaluate ∫[6 to 2] (x - 16) dx, we can use the linearity property of integrals:

∫[6 to 2] (x - 16) dx = ∫[6 to 2] x dx - ∫[6 to 2] 16 dx

Substituting the given values, we have:

∫[6 to 2] (x - 16) dx = 16 - 4(6 - 2) = 16 - 4(4) = 16 - 16 = 0

Therefore, the value of ∫[6 to 2] (x - 16) dx is 0.

To find the median of a set of numbers, you first need to put the numbers in order from smallest to largest. Once the numbers are ordered, the median is the middle number in the list.

In this case, the ordered list of numbers is: 2, 3, 3, 4, 5, 6, 7.

The median of this list is 4.

Sorting all the data points and selecting the central one are required to determine the middle number (or if there are two middle numbers, taking the mean of those two numbers). Example: The number 4 is in the middle when the numbers are grouped (1, 4, 7), making it the median of the numbers (4, 1 and 7).

By summing up the center values and dividing them by two, you may obtain the mean and, from there, the median.

The conclusion of the Mean Value Theorem holds for the function f(x) = x³ on the interval [-8, 8] at the points c = 8/√3 and c = -8/√3.

The Mean Value Theorem states that if f(x) is a continuous function on the closed interval [a, b] and differentiable on the open interval (a, b), then there exists at least one point c in the open interval (a, b) such that:

f'(c) = [f(b) - f(a)]/(b - a)

In this case, the function f(x) = x³ is continuous on the closed interval [-8, 8] and differentiable on the open interval (-8, 8), since it is a polynomial function. Therefore, we can apply the Mean Value Theorem to find the point(s) at which the conclusion holds.

First, we find the values of f(-8) and f(8) as follows:

f(-8) = (-8)³ = -512

f(8) = 8³ = 512

Next, we find the derivative of f(x) using the power rule of differentiation:

f'(x) = 3x²

Then, we can use the Mean Value Theorem to find the point(s) c at which the conclusion holds:

f'(c) = [f(8) - f(-8)]/(8 - (-8))

f'(c) = [512 - (-512)]/16

f'(c) = 64

Now, we need to find the value(s) of c that satisfy the equation f'(c) = 64. To do this, we set f'(c) = 64 and solve for c:

3c² = 64

c² = 64/3

c = ±(8/√3)

The two minus signs "cancel." The product of any set of numbers with an even number of minus signs will be positive.

There are 2 pounds of apples Hannah buy for the cost for her purchase to be the same from both stores.

Given that;

At Giant Eagle, a box of cereal costs $2.89 and apples cost $1.29 per pound.

And, At Shop & Save, the apples are $1.05 per pound and a box of

cereal is $3.37.

Now,

Let number of pounds of apples can Hannah buy for the cost for her purchase to be the same from both stores = x

So, We can formulate;

For, At Giant Eagle, a box of cereal costs $2.89 and apples cost $1.29 per pound.

The total cost is,

⇒ $2.89 + $1.29x

And, For Shop & Save, the apples are $1.05 per pound and a box of

cereal is $3.37.

Total cost is,

⇒ $3.37 + $1.05x

Now, We can equate both the equation to find the number of pounds of apple to buy.

⇒ $3.37 + $1.05x = $2.89 + $1.29x

⇒ 3.37 + 1.05x = 2.89 + 1.29x

⇒ 3.37 - 2.89 = 1.29x - 1.05x

⇒ 0.48 = 0.24x

⇒ x = 0.48 / 0.24

⇒ x = 2

The best estimate for the population parameters is Option A: "a mean of 4.9 letters and a standard deviation of 1.5 letters", because these values match the estimates for the sampling distribution. 

The mean and standard deviation of the sampling distribution give us an idea of the spread and central tendency of the data. In this case the mean was 4.9 letters and the standard deviation was 0.15 letters. This suggests that the mean word length for the textbook is 4.9 letters & that the values are tightly clustered around this central value.

Therefore it is more likely that the population parameters would be similar to these estimates.

Answer:

Step-by-step explanation:

Not sure where though

Comparing the means of the two samples, we find that the difference between the means is significant. Therefore, we can reject the claim and conclude that male and female high school students have different exam scores.

To perform the two-sample t-test, we first calculate the standard error of the difference between the means using the formula:

SE = sqrt((s1^2 / n1) + (s2^2 / n2))

Where s1 and s2 are the population standard deviations of the male and female students respectively, and n1 and n2 are the sample sizes. Plugging in the values, we have:

SE = sqrt((47^2 / 49) + (4.3^2 / 53))

Next, we calculate the t-statistic using the formula:

t = (x1 - x2) / SE

Where x1 and x2 are the sample means. Plugging in the values, we have:

t = (239 - 21.1) / SE

We can then compare the t-value to the critical t-value at α = 0.01 with degrees of freedom equal to the sum of the sample sizes minus 2. If the t-value exceeds the critical t-value, we reject the null hypothesis.

In this case, the t-value is calculated and compared to the critical t-value using the provided standard normal distribution table. Since the t-value exceeds the critical t-value, we can reject the claim that male and female high school students have equal exam scores.

Therefore, the correct answer is:

B. Male and female high school students have different exam scores.
