Answer:

Step-by-step explanation:

Out of all of the answers provided, H seems like the equation that makes the most sense.

$(60 * 3) = 180$

$[480 - (180)] = 300$

$300 = 60$

Make sure you divide 300 sticks by 60 sticks (box max) to get the number of boxes.

$300 / 60 = 5$

So, Mr. Hanson would need to have 5 more boxes in order to get the total amount of 480 sticks.

From that, H would be considered the best equation that Mr. Hanson would use.

Kazeer [188]

Answer: The average was 9 years old find the average age of both groups is 10 years old.

Step-by-step explanation:

Formula foe average : $\text{Average} =\dfrac{\text{Sum of all observations}}{\text{Number of observations}}$

Given : The first group of students consists of 10 and their average age was 13 years old.

i.e. $13=\dfrac{\text{Sum of ages of students of first group}}{10}\\\\\Rightarrow\ \text{Sum of ages of students of first group}=13\times10=130$ (1)

The next group consisted of 30 students and their average was 9 years old.

i.e. $9=\dfrac{\text{Sum of ages of students of next group}}{30}\\\\\Rightarrow\ \text{Sum of ages of students of nextgroup}=9\times30=270$ (2)

Then from (1) and (2) , the sum of both groups (first group and next group )students = 130+270 =400

Combined students of both groups (first and next group )= 10+30=40

Now , the average of both groups = $\dfrac{\text{Sum of combined students}}{\text{combined students}}$

$=\dfrac{400}{40}=10$

Hence, the average was 9 years old find the average age of both groups is 10 years old.
