Answer: and
Step-by-step explanation:
In sampling distribution of .
The mean and standard deviation of the sampling distribution of p is given by :-
, where p= population proportion and n= sample size.
Let p be the population proportion of unmarried couples in the United States are mixed racially or ethnically.
As per given , we have
n = 100
p= 14% =0.14
Then, the mean and standard deviation of the sampling distribution of p will be :
Hence, the required answer : and
Distance = rate*time
convert minutes to hour first because the question talking about 15 mile per hour
40 mins = 40/60 2/3 hrs
30 mins = 30/60 = 1/2hrs
Assume that s be the speed when Fritz driving, so
s + 15 will be the speed of the train.
We know the time we know the speed, Next
distance that Fritz drive =
distance the train travel =
The question: Assume that the train travels the same distance as the car

Now we know that Fritz drive at 45 mph,
distance =
