Answer:
m = 3/5
Step-by-step explanation:
Slope Formula: 
Step 1: Find 2 coordinates
(0, 80)
(-50, 50)
Step 2: Find slope <em>m</em>
m = (50 - 80)/(-50 - 0)
m = -30/-50
m = 3/5
1 mile is equal to 1.6 kilometers, so 8 miles (using a direct proportion) should be equal to 8 * 1.6 = 12.8 kilometers. The cyclist rides at 12.8 kilometers per hour. In four hours, the cyclist would have rode 12.8 * 4 = 48 + 3.2 = 51.2 kilometers.
Answer:
The value of f approaches P(E) when the value of N is very large. Think of the probability of event E as the fraction of times E occurs when the trial is repeated a great number of times.
