The shaded region shown in the graph of the normal distribution corresponds to P(x < 92.5).

An equation is an expression that shows the relationship between two or more numbers and variables.

The z score shows by how many standard deviations the raw score is above or below the mean. It is given by:

z = (raw score - mean)/standard deviation

The diagram represents z < 1.5 mean = 100, standard dev = 5 hence:

-1.5 = (x - 100)/5

x = 92.5

The shaded region shown in the graph of the normal distribution corresponds to P(x < 92.5).
