Step 1: Find the GCF. List out the factors of the numerator and the denominator. 1, 3, 9 are the factors of 9, while 1, 2, 3, 4, 6, 9, 12, 18, and 36 are the factors of 36. 9 is a common factor of both of them, so the GCF is 9.
Step 2: Divide the numerator and denominator by 9 (the GCF). 9/9 is 1. 36/9 is 4. This means that our fraction is 1/4. The fraction is in simplest form.
The formula for acceleration is (∆v)/(∆t), or (final velocity - initial velocity)/(final time - initial time). If you input your values the problem would work out as followed:
A = <span>(∆v)/(∆t) A = (25-9)/(8-5) A = 16/3 A = 21.33 (rounded to the nearest hundredth)</span>
There is a bias in this sampling method. The interviewer only interviews people exiting a local restaurant, which means it's more likely for the people to go out to eat regularly. If he wanted an interview with no bias, he should go out and interview random people on the street, not in front of any business.
