Answer:
65.426
Step-by-step explanation:
Given that:
Mean height (m) = 68 inches
Standard deviation (s) = 2 inches
Height required to be taller than 90% of the class :
P(Z > x) = 0.9
The corresponding Zscore is - 1.282 (Z probability calculator)
Using the Zscore relation :
Zscore = (x - m) / s
-1.282 = (x - 68) / 2
-1.282 * 2 = x - 68
-2.564 = x - 68
-2.564 + 68 = x
x = 65.436
The logarithmic function when the temperature is 64 degrees is given as
ln f(x) = x ln 2.

What is a logarithmic function?</h3>
A logarithmic function is the inverse of an exponential function. It is to be noted that all exponential functions can be written as logarithmic functions.
Hence, to convert the mathematical statement above into a logarithmic function we say:
f(x) = 2ˣ
ln f(x) = ln 2ˣ
ln f(x) = x ln 2
Ln 64 = x Ln 2
Let f(x) = 64;
Hence,
Ln 64 = x ln 2
Divide both sides by ln 2 to get x
ln 64/ln 2 = x
Hence,
x = ln 64/ln 2
= 6
