The average temperature for July over the past 30 years in Eloy and Arizona is 90°. The standard deviation is 2.1°. This implies that the temperature over these 30 years spans from 90° - 2.1° to 90° + 2.1°, which equals 87.9° to 90°. The average for the last five summers in Eloy and Arizona is 92°. To calculate the reduction, which is 2.5% from 92, we find that 89.70° is within the 87.9° to 90° range. Thus, it can be concluded that the two averages are likely identical.
To determine the lateral area of the pentagonal prism illustrated in the figure, we begin the calculation.
According to the definition:

Where:
: Represents the lateral area
: Refers to the perimeter of the base
h: Denotes the height
By substituting the known values:

Result:

Is the process like this: 38+29=67, then 67-23=44
50-44=6
thus possibly A?
