Step-by-step explanation:
<u>Step 1: Define Inequality</u>
h - 8 > 4h + 5
<u>Step 2: Solve for </u><em><u>h</u></em>
- Subtract <em>h</em> on both sides: -8 > 3h + 5
- Subtract 5 on both sides: -13 > 3h
- Divide 3 on both sides: -13/3 > h
- Rewrite: h < -13/3
Here we see that any value <em>h</em> smaller than -13/3 would work as a solution to the equation.
A good estimate would be 3.
The probability that someone works in the office building and rides the subway to work is 28/120. There are 13 people in the office, so
28/120(13) = 364/120 = 3.03 ≈ 3 people would be the number you would expect to have ridden the subway.
