Answer: $0.05
Step-by-step explanation:
Mean of a given set of numbers simply means that one should find the average of the numbers. Therefore, the mean change of the stock prices will be:
= ($1.25 + -$0.75 + $1.25 + -$0.75 + -$0.75) / 5
= $0.25 / 5
= $0.05
Therefore, the mean change of the stock prices is $0.05.
<span>The volume of a pyramid is 1/3 the volume of the cube mentioned in the question since it fits exactly inside it. So multiply 49*3 = 147 cubic feet...
