In 12 games last season the school baseball team scored 5, 11, 2, 0, 4, 8, 9, 6, 7, 4, 1, and 2 runs. What is the average number

Mashcka [7]

Hello there!

First, we need to put our data set into proper numerical order (least to greatest).

Set: , 1,2,2,4,4,5,6,7,8,9,11

Now, to find the mean, we need to add them all up.

1 + 2 + 2 + 4 + 4 + 5 + 6 + 7 + 8 + 9 + 11 = 59

Then, divide it by how many numbers there are : 12

59 divided by 12 = 4.9166667

Round it to the nearest tenth.

4.9166667 = 4.9

This means the average number of runs scored per game is 4.9 runs.

Which of the following is equivalent to x+1/y divided by g+1/h

Vikki [24]

Answer:

B) x + 1/y times h/g+1

Step-by-step explanation:

We need to divide $\frac{x+1}{y}$ by $\frac{g+1}{h}$ then match with given choices to find the correct equivalent result.

where given choices are:

A) x/y times h/g

B) x + 1/y times h/g+1

C) x+ 1/y divided h/g+1

D) y/x+1 divided g+1/h

So let's divide $\frac{x+1}{y}$ by $\frac{g+1}{h}$

$\frac{\left(\frac{x+1}{y}\right)}{\left(\frac{g+1}{h}\right)}$

we are allowed to flip the bottom fraction and change division sign into multiplication. So we get:

$=\left(\frac{x+1}{y}\right)\cdot\left(\frac{h}{g+1}\right)$

Hence correct choice is: B) x + 1/y times h/g+1
