The proportion of the generated values that fall inside the range of each histogram bar is used to compute the vertical scale. The standard deviation is an indicator of how much the values in the data set typically deviate from the mean.

What is the difference between standard deviation and histogram?

It always displays the median and the middle 50% of the data. For data displayed in histograms, a similar spread measurement is helpful. The term for it is the standard deviation. The standard deviation is an indicator of how much the values in the data set typically deviate from the mean.

The proportion of the generated values that fall inside the range of each histogram bar is used to compute the vertical scale. The sum of the bar heights is therefore one. Only discrete variables (right), where the histogram heights now total to unity, are suitable for relative frequency analysis.

A measurement of how far points deviate from the mean is the standard deviation. The first histogram includes fewer points that are close to the mean and more points that are distant from the mean (scores of 0, 1, 9, and 10). (scores of 4, 5 and 6). As a result, its standard deviation will be higher.

The proportion of a population with a characteristic of interest is p = 0.37. What is the standard deviation of the sampling distribution when the sample size is 1,600?

Answers

The standard deviation (SD) of a sample proportion obtained when the sample size is 1,600 is equal to 0.0121.

What is a sample proportion?

A sample proportion can be defined as the proportion of individuals in a sample that have a specified characteristic or trait.

Mathematically, sample proportion can be calculated by using this formula:

[tex]\hat{p} = \frac{x}{n}[/tex]

Where:

x represent the number of individuals with a specified characteristic.n represent the total number of individuals in a sample.

In Mathematics, the standard deviation (SD) of a sample proportion obtained when the sample size is 1,600 can be calculated by using this formula:

Standard deviation (SD) = √(p(1 - p)/n)

Substituting the given parameters into the formula, we have;

Standard deviation (SD) = √(0.37(1 - 0.37)/1,600)

Standard deviation (SD) = √(0.37(0.63)/1,600)

Standard deviation (SD) = √(0.2331)/1,600)

Standard deviation (SD) = √0.0001457

Standard deviation (SD) = 0.0121.

It says if Jamal rides his bike to school and back home. It is two miles each way. How many miles does he ride in five days?

Answers

Answer:

20 miles

Step-by-step explanation:

If it is two miles each way, then he rides a total of 4 miles every day.

Multiply 4 by 5

4 x 5 = 20

20 miles

Answer:

20 miles

Step-by-step explanation:

he always goes to school and comes back, to that means each day where he goes to school he rides 4 miles each time.

if he does this for 5 days you can write the following:

4*5 = 20 or if you haven't learned multiplication you can think of it like this:

Answers

The simplified expression of the fraction expression is (b) One group of 4/6, with 1/6 remaining.

How to evaluate the fraction?

The fraction expression is given as

ten StartFraction 1 Over 12 EndFraction bars.

Rewrite the fraction properly

So, we have

Ten 1/12 bars

This can be represented as

10 * 1/12

Rewrite 10 as 10/1

So, we have the following equation

10 * 1/12 = 10/1 * 1/12

Evaluate the products of the numerator

So, we have the following equation

10 * 1/12 = 1/1 * 10/12

Evaluate the products of the denominator

So, we have the following equation

10 * 1/12 = 10/12

Simplify the fraction

10 * 1/12 = 5/6

Split the fraction

10 * 1/12 = 4/6 + 1/6

This means that, the result is

Quotient = 4/6 and remainder = 1/6

What is percentage?

The Latin word "per centum," which means "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentages are fractions. To put it another way, it's the relationship between a component and a whole in which the value of the whole is always assumed to be 100.

Given that : A toy store is having a sale on puzzles. For each puzzle, Naomi buys she gets 75% off of a second puzzle. The original price of each puzzle is $16.50. Naomi bought 4 puzzles

An inground sprinkler nozzle sprays water onto the grass in the shape of a circle, with the nozzle at the center of the circle. On the coordinate plane, the nozzle is located at (20, 0) and the points (35, 0) and (5, 0) lie on the circle. Which equation represents the boundary that the sprinkler covers?

Answers

In order to determine which equation represents the boundary, replace the values of the coordinates of the given points, into the choices for the equations, and then verify if the left hand side matches with the right hand side.

For points (35,0) and (5,0) you have:

x = 35

y = 0

x = 5

y = 0

Then, for the first answer choice we have:

[tex]\begin{gathered} (x-20)^2+y^2=225 \\ (35-20)^2+0^2= \\ 15^2=225 \\ (5-20)^2+0^2= \\ 15^2=225 \end{gathered}[/tex]

As you can notice, the equation matches for values of x and y.

Then, there is no necessary to verify for the other choices.

Hence, the equation (x - 20)^2 + y^2 = 225 represents the boundary that the sprinkler covers.

If 3 dogs eat 4 pounds of food per day, how many dogs eat 15 pounds of food?

Answers

11 dogs will eat 15 pounds of food.

According to the question,

We have the following information:

3 dogs eat 4 pounds.

We have to find how many dogs will eat 15 pounds.

We have the following expression:

4 pounds = 3 dogs

We can treat dog as a non-living object or a product.

So, we can find the parts devoted to 1 pound:

1 pound = 3/4

Now, we have to find the same for 15 pounds:

15 pounds = (3/4)*15

15 pounds = 11.25

Now, note that the number of dogs can not be in points. So, we will round it off to form a whole number.

So, 15 pounds = 11 dogs

Hence, 15 pounds of food is enough for 11 dogs.

Navy paint is made by mixing 8 cups of blue paint with 2 cups of black paint. If he only has 1 cup of blue pain, how much black paint should he use?

Answers

For 1 cup of blue paint, 1/4 cups of black paint is needed

How to determine the amount of black paint?

The given parameters are

8 cups of blue paint needed for 2 cups of black paint

This means that

8 cups of blue paint needed = 2 cups of black paint

Divide both sides of the equation by 8

So, we have the following equation

8/8 cups of blue paint needed = 2/8 cups of black paint

Evaluate the quotient

So, we have the following equation

1 cup of blue paint needed = 1/4 cups of black paint

Hence, the amount of black paint is 1/4
