REY [17]
<span>There are 4 vans. So we have that probability that the first vehicle is a van p (e) = 4/10 = 0.4. P(e|f) = P( f and e) / p (f) p(e) = 0.4 and p(f) = 3/9 P (f and e) = 0.40 * 0.33 = 0.132 So p(e|f) = 0.4 * 0.33/ 0.33 = 0.4 P(f and e) p(f) * p(e) = 0.4 * 0.33 = 0.132</span>

a map has a scale of 6 in : 36 mi. If Clayton and Clinton are 52 mi apart, then they are how far apart on the map?
cricket20 [7]
The map scale is 6 in : 36 mi

simplify it, divide 6 from both sides

6/6 = 1
36/6 = 6

1 in : 6 mi

To find the amount of inches in 52 miles, divide 52 with 6

52/6 = 8.67 (rounded)

8.67 in should be your answer

hope this helps
