Answer: 5
Explanation step-by-step: There are six boxes stacked between the top of the third box and the bottom of the tenth box.
Since each box measures 10 inches in height, the combined height of these six boxes is 60 inches.
Given that 12 inches equals 1 foot,
60 inches corresponds to 5 feet.
How to find the answer:
Let "y" represent the unknown length in feet.
12 inches = 1 foot
60 inches = y
Using cross multiplication:
> 12 × y = 60 × 1
> 12y = 60
Divide both sides by 12 to solve for "y":
> 12y ÷ 12 = 60 ÷ 12
After simplification, we get:
> y = 5
The diagram below illustrates the normal distribution curve. The likelihood that his commuting time surpasses 61 minutes is represented by the area under the standard normal curve located to the right of X=61. To determine the z-score, we standardize X=61.
