Diameter of cylinder = 12 inches

radius of cylinder (r) = 1/2 x diameter = 6 inches

Height of cylinder (h) = 1.25 feet

We can convert feet to inches using the relation: 1 foot = 12 inches

So, 1.25 feet = 12 x 1.25 inches

=> 15 inches

The volume of the cylinder is given by:

Upon substituting the values of r and h

The theorem that states that the sampling distribution of the sample mean is approximately normal when the sample size n is reasonably large is known as the Central Limit Theorem

The Central Limit Theorem is a statistical theorem that states that, given a sufficiently large sample size, the distribution of the mean of any sample will be approximately normal, regardless of the shape of the distribution from which the sample was drawn.

In other words, the theorem states that the mean of a large sample will be close to the mean of the population, and that the standard deviation of the distribution of the sample mean will be small.

The theorem is important because it provides a way to approximate the distribution of any sample statistic, as long as the sample size is large enough. This is useful because many statistical tests, such as hypothesis tests and confidence intervals, require that the data be normally distributed.

The theorem is also important because it provides a way to quantify the amount of error that is introduced when a sample is used to estimate a population parameter. This is known as the standard error, and it is equal to the standard deviation of the distribution of the sample mean divided by the square root of the sample size.

The Central Limit Theorem is one of the most important theorems in statistics, and it is widely used in many different fields.

Answer:

m=9/5

Step-by-step explanation:

The equation that could be used to solve for x is (3x-1) = 140 and the value of x is 47°.

According to the question,

We have the following information:

We have two lines that are intersecting each other at a point. The angles made on this point are given.

Now, we know that these two angles are vertically opposite angles. And we also know that vertically opposite angles are equal.

So, we will have the following equation:

3x-1 = 140

Now, we can easily find the value of x from this equation:

Adding 1 on both sides of the equation:

3x = 140+1

3x = 141

Dividing by 3 on both sides:

x = 141/3

x = 47°

Hence, the equation that could be used to solve for x is (3x-1) = 140 and the value of x is 47°.

Answer:

y>= -27/16

Step-by-step explanation:

I just put in the calculator

Given the system of the equations:

y = x + 4

x + y = 2

By substitution with y from the first equation at the second equation

so,

x + (x+4) = 2

solve to find x

so,

x + x + 4 = 2

2x = 2 - 4

2x = -2

Divide both sides by 2

x = -2/2 = -1

Substitute at the first equation with x to find y

So, y = -1 + 4 = 3

so, x = -1 and y = 3

so, the order pair which a solution is (-1 , 3)

(4x +1)(4x -1)​

Apply the distributive property:

4x (4x ) + 4x (-1) + 1 (4x) + 1 (-1)

16x^2 -4x + 4x -1

Combine like terms:

16x^2-1

Answer:

16x² - 1

Step-by-step explanation:

(4x + 1)(4x - 1)

each term in the second factor is multiplied by each term in the first factor , that is

4x(4x - 1) + 1(4x - 1) ← distribute parenthesis

= 16x² - 4x + 4x - 1 ← collect like terms

= 16x² - 1

The number of win and losses of the volleyball team is related by a constant number, 3. This means that they're proportional. To find if the other teams also have proportional win-loss records we need to divide the number of their wins by the number of losses, if the result is an integer number, then they're proportional. We have:

Since the football team has a proportional win-loss record with the same proportion as the Volleyball team, then this is the correct answer.

What is distance?

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in common usage.

Given: Joshua likes to make sure he gets enough exercise, so he always moves at least 4 1 /4 miles each day.

On days when he doesn't walk, he runs all that distance at the gym.

But  he walks 2 blocks, he cuts of 1/12 a mile off his run.

Today Joshua walked 12 blocks.

As he walked 12 blocks - 6 times 1/12 miles - so that's 0.5 a mile he cut from the exercise.

He will run at the gym for 4.25 - 0.5 = 3.75 miles in total.

4.25 - 6(1/12) = 3.75

Therefore, 3.75 miles he run at the gym.

Substitute:

[tex]m=\dfrac{13-3}{5-0}\\\\m=\dfrac{10}{5}\\\\\boxed{m=2}[/tex]

Answer:

Slope = 2

Step-by-step explanation:

Now we have to,

→ find the slope of the line.

Formula we use,

→ Slope(m) = (y2 - y1)/(x2 - x1)

Then the slope will be,

→ m = (y2 - y1)/(x2 - x1)

→ m = (13 - 3)/(5 - 0)

→ m = 10/5

→ [ m = 2 ]

Hence, the slope is 2.

170 - 30h ≤ 74

Given, Raj has put a soup intot he freezer to cool down.

The soups temperature started at 170 °F and decreased at a rate of 30 °F per hour.

Let h represent the number of hours the soup stays in the freezer.

Raj wants the soup to cool down so that its temperature, when he takes it out of the freezer, is at most 74 °F.

we are asked to determine  an inequality in terms of that represents all times when the soup is cool enough for Raj to take it out of the freezer.​
