This translates to "a number" is greater than 45. All you have to do now is translate these words into an algebraic statement. Basically, you replace "a number" with the variable which it is defined for, and you use the "greater than" symbol to show that the variable is greater than the value of 45.

Answer: 1.375 inches
Step-by-step explanation:
1.98 x 10^-12 1.98
------------------ = ---------- x 10^-10
3.6 x 10^-2 3.6
=0.55 x 10^-10
=5.5 x 10^-11
This is 2.5 standard deviations from the mean.
We find this by subtracting the mean from our value, and dividing by the standard deviation:
(63-38)/10 = 25/10 = 2.5
