Question

ExplanationCheckX3(a) Move the cubes so that each stack has the same number of cubes.Then give the number of cubes in each stack.(b) What is the mean of 8, 6, 8, 4, and 9?(These are the numbers of cubes in the original stacks.)0(c) Are the values you found in parts (a) and (b) the same? Why or why not?No. But it didn't have to turn out that way. When the stacks are made equal,the number of cubes in each stack may be the mean of the original stacks.I need help with this math problem.

Answer 1

a. After moving the cubes so that each stack has the same number of cubes, we got 7 cubes in each stack.

Explanation:

In total, there are 35 cubes. Since there are 5 stacks, we divide 35 by 5 and got 7. Hence, there must be 7 cubes in each stack.

b. To determine the mean, simply do the same process above. Add the given numbers and divide the sum by the total numbers given.

$8+6+8+4+9=35$

Since there are 5 numbers, divide 35 by 5.

$35\div5=7$

Hence, the mean is 7.

c. Yes, the values in parts a and b are equal. When we make the stacks equal, the number of cubes in each stack must be the mean of the original stacks because the mean is the average of the number of stacks. (Option 3)
