Step-by-step explanation:
At time 2:00 PM
A car reads = 30 mi/h
At time 2:20 PM
A car reads = 50 mi/h
Now,
At time 2:00 PM
t = 0
At time 2:20 PM
t = 


For MVT,



Parallel means lines that never meet, and perpendicular are lines that meet at right angles.
Answer:
D 200 and 2
Step-by-step explanation:
standard error of the sampling distribution of sample mean is expressed using the formula;
Standard error of the mean = S/√n where;
S is the standard deviation
n is the sample size
Given
S = 18
n = 81
SEM = 18/√81
SEM = 18/9
SEM = 2
The mean of the distribution according to the question is 200.
Hence the mean and the standard error of the sampling distribution of sample mean are 200 and 2 respectively.
5)B
6)A

Im not 100% sure about 7 but i believe those are correct
