Answer:
Null Hypothesis:
Alternate Hypothesis:
Step-by-step explanation:
The claim made by the company should be that: Using the company's product will slow down the facial growth. According to the study, the average man's facial hair grows a half an inch per month. So, the claim of the company will be that using its product the average growth will be less than half an inch. Since, the claim contains the word "less than", it will be the alternate hypothesis.
The Null hypothesis, therefore, would be: The average growth is half an inch per month.
Let u represents the growth of facial hair growth per month. The Null and Alternate Hypothesis in symbolic forms would be:

Answer:
i think it is 16
Step-by-step explanation:
16 + 7 = 23
We know that
1 mile----------------> 1609.34 meters
26 miles---------------> X
X=26*1609.34=41842.84 m
I apply a rule of three to know the time
if 100 m---------------9.96 sec
41842.84 m----------> x
x=41842.84*9.96/100=4167.5468 sec
to get minutes I divide it by 60---------> 4167.5468/60=69.459113 minutes
to get hours I divide it by 60----------> 69.459113/60=1.1576518 hours
1.1576518= 1 hour 9 minutes 27.55 sec
the answer is 1 hour 9 minutes 27.55 sec------->(4167.5468 sec)
I think the answer would be B.
