Answer: Around 100 people will answer that they prefer professional football.
Step-by-step explanation:
In the north, 70 out of 84 prefer professional football, then the relative frequency is
p = 70/84 = 0.83
Now, in the south, they asked to 120 people, and we can assume that the relative frequency will be about the same than in the north (because the relation is independent, which means that the region does not affect on the answer to the question of if they prefer professional or college football), so we have that if X people prefer professional football, we have:
p = X/120 = 0.83
X = 120*0.83 = 100
So around 100 people will answer that they prefer professional football.

Isabel lives 1/12 mile farther than Janet from the school.
Given that, Isabel lives 3/4 mile from school, and Janet lives 2/3 mile from the school.
We need to find how much farther in miles does Isabel live from school than Janet.
Addition and subtraction of unlike fractions:
Step I: Obtain the fractions and their denominators.
Step II: Find the LCM (least common multiple) of the denominators.
Step III: Convert each fraction into an equivalent fraction having its denominatorequal to the LCM (least common multiple) obtained in Step II.
Now, 3/4-2/3=9/12-8/12
=1/12
Therefore, Isabel lives 1/12 mile farther than Janet from the school.
