If you round 75 to the nearest tenth it would be 80
Let
be the number of boxes the team brings with them. Their weight combined with the boxes can't exceed the capacity of 1400. Assuming the elevator runs fine at that exact weight, you want to find the number of boxes, each of which contributes 40 pounds. This is given by the equation
Solving for
, you have
So the team can bring *at most* 5 boxes at a time.
To evaluate when plugging in numerical values for variables, simply put the numerical values in the place of the corresponding variables:
Answer:
It becomes lower
Step-by-step explanation:
This is because as the lowest value becomes larger, <em>one of the values becomes closer to the mean</em>, and as more numbers are closer to the mean, the standard deviation becomes lower.
