4 0

Answer:

2.33 or 2 1/3

Step-by-step explanation:

First you add up all the numbers in the frequency column to get 30. Then you multiply each row of conceded goals by their frequency. 0 x 2 = 0, 1 x 8 = 8, 2 x 4 = 8, etc. You add all of your answers up to equal 70. Then you divide 70 by the number of conceded goals, which is 30. 70/30 = 2.33 or 2 1/3.

I could be wrong for the number that you divide 70 by.. It might be 70/5 which equals 14. You might have to divide by 5 instead of 30 based on the number of conceded goals instead of the frequency. You might want to check for sure.

I hope this helps :)

Are these two expressions equivalent? Use the
Rina8888 [55]

Answer:

No, they are not equivalent

Step-by-step explanation:

8x + 3(x + y)

8x + 3x + 3y

11x + 3y

7x + 7y + 4x + 4y

11x + 11y

They are not equivalent because in one of the equations, the like terms add up to 11y which is different from the other equation which adds up to 3y.

I hope this helps.

A normal distribution has a mean 20 and standard deviation 5. What is the z score that corresponds to the value x=222
sashaice [31]

Answer: The z score that corresponds to the value x=22 is 0.4 .

Step-by-step explanation:

Given : A normal distribution has a mean 20 and standard deviation 5.

i.e. \mu=20

\sigma=5

Let x be the random selected variable.

We know that to find the z-score corresponds to the value x is given by :-

z=\dfrac{x-\mu}{\sigma}

For x = 22, we have

z=\dfrac{22-20}{5}=\dfrac{2}{5}\\\\\Rightarrow\ z=0.4

Hence, the z score that corresponds to the value x=22 is 0.4

Find the volume of the triangular pyramid to the nearest whole number
Marina CMI [18]

Answer:

906 inches³

Step-by-step explanation:

The volume of a triangular pyramid = 1/3 (area of base) × h

area of the base = 1/2 × 19 × 13 = 123.5 inches²

v = 1/3 × 123.5 × 22 = 905.666... ≈ 906 inches³

The volume of the triangular pyramid is 906 inches³

Hope this helps!
