The solution is
(2,1)
So the value of the x-coordinate is 2
First, we must find the z-scores for each limit
for 54
z = (54 - 58) / 4 = -1
For this z-score, the area under the curve is 0.1587
for 62
z = (62 - 58) / 4 = 1
The area under the curve is 0.8413
Subtracting the two z-scores:
0.8413 - 0.1587 = 0.6825
Multiplying by 150
150 (0.6825) = 102.39
So, the closest answer is
102
The number of permutations of 4 objects chosen from 8 is given by the function
P(n, k) = n!/(n-k)!
where you have n=8 and k=4.
It gives the result P(8, 4) = 8·7·6·5 = 1680.
You can see that this is the result you would get when you consider that the first selection can be any of 8, the next selection any of the remaining 7, the next any of the remaining 6, and the final selection any of the remaining 5. The number of possible arrangements is the product of these numbers of possible selections. (The final number may need to be adjusted if there are unimportant distinctions between the arrangements—as rotations of a circular arrangement, for example.)

The radius of a circle is half the diameter.
Radius = 22/2 = 11 inches.
