Answer:
29.27% probability that it takes Ariana between 58 and 70 seconds to do a math problem
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d, d being greater than c, is given by the following formula:

Uniformly distributed between 38 seconds and 79 seconds.
This means that 
What is the probability that it takes Ariana between 58 and 70 seconds to do a math problem

Answer:
x=-8 where A=1 and B=0
Step-by-step explanation:
The given line's graph is x=-8. Since there is no y, they coefficient in front of y, B, will be 0, and since there is only one x, that coefficient in front of the x, A, will be 1.
Answer:
- After 17 years and 3 months
Step-by-step explanation:
<u>Given function:</u>
We are looking for the value of x at f(x) < 2000
<u>Solve the equation:</u>
- 2000 = 18000(0.88)^x
- (0.88)^x = 2000/18000
- (0.88)^x = 0.1111
- log (0.88)^x = log 0.1111
- x = log 0.1111 / log 0.88
- x = 17.18
After 17 years and 3 months the car value drops below $2,000
