Answer:
Step-by-step explanation:
The difference in fixed cost is $9; the difference in per-mile cost is $0.02. The difference in per-mile cost will equal the difference in fixed cost for a distance of ...
$9.00/($0.02/mi) = 450 mi
At that distance, the rental cost is ...
$50 +450×$0.15 = $50 +67.50 = $117.50
Both plans will cost $117.50 for 450 miles of driving.
Answer:
A) Fill the blanks, Fail, 0.15, Success, 244, 0.61
B) 240 times
Step by-step explanation:
A) Void , 96, 0.24
Fail, 60, it should be 0.15 because 60/400
Success, 400 - 96- 60 or 244 and the relative frequency is 0.61.
B)
There is a total of 1000. If the relative frequency is 0.24, multiply 0.24 by 1000 to get the amount of times YOU would expect to be VOID.
Or in other words , 240 times
By proving it add all up
0.24 x 1000 + 0.76 x 1000 = 1000
