Step-by-step explanation:

Take a look at the given question,

"75% of what number is 15"

Let's substitute this "what number" as "x"

[tex]75[/tex]%[tex] \times x = 15[/tex]

[tex]→x = \frac{15}{75 \: percent} [/tex]

[tex]→x = \frac{15}{ \frac{75}{100} } [/tex]

[tex]→x = \frac{15}{0.75} [/tex]

To make the denominator as positive for making calculations more easy, we get,

[tex]x = \frac{15 \times 100}{0.75 \times 100} [/tex]

[tex]→x = \frac{1500}{75} [/tex]

Now after doing the division, we get,

[tex]x = 20[/tex]

Hence, 75% of 20 is 15.

Answer:

Step-by-step explanation:

The answer is -6 :)

1. Add 40 to both sides of the equation.

-8x-40=8

-8x-40+40=8+40

2. Add the numbers.

-8x=48

3. Divide both sides of the equation by the same term.

-8x=48

[tex]\frac{-8x}{-8}[/tex]=[tex]\frac{48}{-8}[/tex]

4. Cancel terms that are in both the numerator and denominator and divide the numbers.

x=-6

hope this helped! :)

Answer:

  20

Step-by-step explanation:

The grid lines are 1 unit apart, so you can determine the dimensions of the trapezoid by counting grid squares. The parallel bases have lengths 6 and 2. They are 5 units apart.

The area is given by ...

  A = 1/2(b1 +b2)h

  A = 1/2(6 +2)(5) = 20

The area of the trapezoid is 20 square units.

Using the binomial distribution, considering the probability of each event, the correct histogram is the fourth one.

For each question, there are only two possible outcomes, either the student guesses the correct answer, or not. The probability of guessing the correct answer on a question is independent of any other question, hence the binomial distribution is used to solve this question.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

Then, the probabilities are as follows:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{5,0}.(0.5)^{0}.(0.5)^{5} = 0.03125[/tex]

[tex]P(X = 1) = C_{5,1}.(0.5)^{1}.(0.5)^{4} = 0.15625[/tex]

[tex]P(X = 2) = C_{5,2}.(0.5)^{2}.(0.5)^{3} = 0.3125[/tex]

[tex]P(X = 3) = C_{5,3}.(0.5)^{3}.(0.5)^{2} = 0.3125[/tex]

[tex]P(X = 4) = C_{5,4}.(0.5)^{4}.(0.5)^{1} = 0.15625[/tex]

[tex]P(X = 5) = C_{5,5}.(0.5)^{5}.(0.5)^{0} = 0.03125[/tex]

Hence the fourth histogram is correct.

Answer:

44 students play video games

Step-by-step explanation:

110*0.40 = 44

i hope this helps! have a wonderful rest of ur day :)

Answer:

40/100

Step-by-step explanation:

40% of 110 is 44 so we make this a fraction 44/110 and then simplify to get 2/5 and after that we know that 2/5 is also 40/100, meaning 40 out of 100 students like video games.

Answer: A

Step-by-step explanation:

The segment passes through the center of the circle, O, and its endpoints lie on the circumference of the circle.

The segment ZX is the diameter of the circle O. Then the correct option is A.

It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The diameter of the circle is the longest chord that is passing through the center of the circle.

The segment ZX is the diameter of the circle O.

Then the correct option is A.

Answer:

Three ways I experience these benefits is 1, being able to vote in free elections, 2, being able to receive an education, and 3, being able to volunteer for things.

Step-by-step explanation:

From the given graph , we see that it passes through the point (0,-1) .

→ y intercept = -1

For finding slope , take another point as (1,3) . Now using the points (1,3) and (0,-1) we can find out the slope as ,

→ m = y2 - y1 / x2 - x1

Substituting the respective values,

→ m = 3 -(-1)/1-0

→ m = 3+1/1

→ m = 4/1

→ m = 4

Hence the slope of the line is 4 and its y intercept is -1 .
