To write:the metric unit of length for the given objects.

Answer to Problem 42P
The length of school bus should be measured in meters.
Explanation of Solution
Given:
Length of a school bus
Calculation:
There are 2 systems for measurement, one is customary system and other is metric system.
Customary has been used historically for various measurements, while metric system is widely accepted due to ease of calculations.
Various units of length in metric system are millimeters, centimeters, meters, kilometers etc.
Since, school bus is quite bigger than normal small things like paper, DVD. And is comparable to things measured in meters like width of road, height of elephant.
It is reasonable to say that length of school bus should be measured in meters.
Conclusion:
Hence, the length of school bus should be measured in meters.

They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king.
