Answer:
y = -3x + 2
Explanation:
Do the rise over run equation to find slope
Slope = 3
Plug in slope to equation and also choose one of the coordinate points to plug in x and y so you can find b
Plug in all of this to get final y=mx+b form
A: We want to select one person who works out three days a week. Our probability is simply 12/80 ~~ 15%
B: At least 4 days a week means 4 days, 5 days, or 6 days.
Hence, we have: (9 + 20 + 8)/80 = 46%
C: At least once a week.
Let's find out how many DO NOT work out and subtract that from our sample space. This means they must work out at least once a week.
(80 - 15)/80 = 81%
Answer:
x is greater than or = to 8
