Answer: 97.7 in
Step-by-step explanation: The perimeter is another name for circumference. Since we know that the formula for circumference is 2(pi)r, but we only want half of that.
Note that 2r is another way of writing the diameter (d).
In this case, we can use the formula d(pi)/2 + d (we’re adding d because d(pi)/2 will only give us the perimeter of the arch.
38(pi)/2 = 59.66
59.66 + 38 = 97.66
Rounded, that would be 97.7 in
Answer:
The value of the test statistic is 
Step-by-step explanation:
The formula for the test statistic is:
In which X is the statistic, 
is the mean, 
is the standard deviation and n is the number of observations.
In this problem, we have that:
So
The value of the test statistic is
14x45=630
43×2=86
(14×45)-(43×2)= 630-86=544
there would be 544 pens left
