Answer:
There are a 25% probability that Christine fails the course.
Step-by-step explanation:
We have these following probabilities:
A 50% probability that Christine finds a tutor.
With a tutor, she has a 10% probability of failling.
A 50% probability that Christine does not find a tutor.
Without a tutor, she has a 40% probability of failing.
Probability that she fails:
10% of 50%(fail with a tutor) plus 40% of 50%(fail without a tutor). So
There are a 25% probability that Christine fails the course.
Answer:
12000-14000 (in miles)
Step-by-step explanation:
We are given that the annual cost of driving a certain car is given by the formula
Where m=Represents the number of miles driven per year
C=Cost in dollars
We have to find the range of miles that Jane can drive her new car.
Range of budgets=$7040-$7780
Substitute C=$7040 in the given formula
Substitute C=$7780 in the given formula
The range of miles that Jane can drive her new car=12000-14000
