In a recent year, there were 15,900,000 high school
students in the United States. Suppose 250,000 of a
random sample of 500,000 high school students
during that year played on a sports team. Estimate
the total number of U.S. High school students that
played on a sports team that year.

Answers

Answer 1

Answer:

The total number of U.S. high school students that played on a sports team that year can be estimated to be 7,950,000.

Step-by-step explanation:

From the random sample, we can expect that [tex]\frac{250000}{500000}=\frac{1}{2}[/tex] of all students played on a sports team that year. So in the bigger sample of 15900000 high school students, we can expect [tex]15900000 \cdot \frac{1}{2} = 7950000[/tex] students to have played on a sports team that year.

Each of 8 students reported the number of movies they saw in the past year. This is what they reported: 18, 10, 20, 18, 12, 19,12, 11 find the mean and median number of movies that the students saw

Answers

Answer:

I. Mean = 15

II. Median = 15

Step-by-step explanation:

Given the following data;

Total number of students = 8

x = 18, 10, 20, 18, 12, 19,12, 11

F(x) = 18 + 10 + 20 + 18 + 12 + 19 + 12 + 11

F(x) = 120

To find the mean;

Mean = F(x)/n

Mean = 120/8

Mean = 15

To find the median;

Median refers to the middle number of a sorted data.

x = 10, 11, 12, 12, 18, 18, 19, 20

Middle numbers = 12 and 18

Median = (12 + 18)/2

Median = 30/2

Median = 15

Explain how to use the distributive property to simplify: -2(x + 5) ?

Answers

Answer:

-2x-10

Step-by-step explanation:

Distributive Property is basically a term for opening parentheses. So, in your case -2(x+5) we would multiply x and 5 by -2. X times -2 is -2x and 5 times negative 2 is -10. -2x-10 would be your final answer.

[tex]\huge\bold{ANSWER:}[/tex]

-2x-10

[tex]\bf{EXPLANATION:[/tex]

Hi there!

Here's what the Distributive Property states:

a(b+c)=ab+ac

So, we take a number outside the parentheses, and "distribute" it.

In this case, we should distribute -2:

-2(x+5)

-2x-10 (a negative times a negative is a positive)

Hope it helps!

Answer:

2 8/9 cups of flour

Step-by-step explanation:

13/3 = flour needed for 3 loaves of bread

13/3 divided by 3 should get you the unit rate

13/3 * 1/3 = 13/9

13/9 is the unit rate. Then, you can multiply by 2

Which measure is of an angle that is coterminal with a 95° angle?

Answers

Answer:

95° - (1,080 n) °, for any integer n

Step-by-step explanation:

Co-terminal angle are those angles who share the same initial side and terminal sides,

And, these angles are obtained by adding or subtracting the multiple of 360°,

That is, if Ф is an angle,

Then its co-terminal angles are,

Ф + 360 n

Where, n is any integer (negative or positive)

Here, Ф = 95°,

Since, n is an integer,

⇒ - 3n is an integer,

Thus, the co-terminal angles of 95° are,

95° + 360° (-3n)

= 95° - (1080 n) °; for any integer n.

Step-by-step explanation:

Solve the Inequality.

[tex]y + 4 < 10 \\ y < 10 - 4 \\ y < 6[/tex]

Therefore, the value of y is lesser than 6. That meane it can't be y = 6 or greater. Hence, 5 is the solution to the Inequality.

Answer

y = 5 is the solution to the Inequality.

But if you want to solve for Inequality only then it is y < 6

Step-by-step explanation:

For number 1

To find percentage you multiply the total number of kids with the percentage.

To do this you have to convert the percent into a decimal by moving the dot 2 times from its original location Ex. 20% = .20 as 20 would look like 20.00 in decimal form.

So .20 x 90 = 18

For number 2

Subtract 18 and 90 to find the remanding kids

For number 3

Divide 72 and 90. Make sure the lower number is being divided.

The answer you will get is .8 so move the decimal back two times because you are converting it to a percentage."

You will then get 80.00 as an answer then from there turn it to a percentage

80%

David has counters. Lisa has 5 more counters than David. Samia has 4 times as many counters as David. The total number of counters is . Write a formula for in terms of . Give your answer in its simplest form.

Answers

Answer:

if 'c' equals number of counters, the answer is 6c + 5

Step-by-step explanation:

david has 'c'

lisa has '5+c'

samia has '4c'

add all terms together:  c + 5 + c + 4c = 6c + 5

The formula for the total number of counters in terms of x is T = 6x + 5

What is the algebraic expression?

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Let's start by expressing the number of counters Lisa has in terms of x. We know that Lisa has 5 more counters than David, so:

Lisa = David + 5

Lisa = x + 5

Next, we need to express the number of counters Samia has in terms of x. We know that Samia has 4 times as many counters as David, so:

Samia = 4 × David

Samia = 4x

Finally, we can express the total number of counters in terms of x by adding up the number of counters each person has:

T = David + Lisa + Samia

T = x + (x + 5) + 4x

T = 6x + 5

Therefore, the formula for the total number of counters in terms of x is T = 6x + 5.

D. {-6, -2, 5}​

Answers

D is the answer, The range of a function is the set of all output values (Y-values).

The range of the given table would be set of all possible y-values as {-6, -2, 5}​ which is the correct answer would be an option (D).

What are the domain and range of the function?

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

We have been given that table as:

x     y

-3    -6

1     -2

7     5

As per the given table, the required solution would be as:

The range of a function is the set of all possible output values of the function. In this case, the output values of the function are the y-values in the table. The range of the function table is the set of all possible y-values, which in this case is {-6, -2, 5}.

Therefore, the range of the function table is therefore -6 to 5.
