Answer:
The frequency distribution does NOT appear to have a normal distribution using a strict interpretation of the relevant criteria.
Step-by-step explanation:
Note: See the attached excel file for the Graph of Temperature (°F) vs. Frequency.
A normal distribution refers to a bell-shaped distribution that begins at a low value, grows to a maximum value, and then declines to a low value again. It is a symmetric and a single-peaked distribution.
The fact that the frequency in the data in this question first fell from 2 to 0 before rising again to 5 indicates that it is neither a bell-shaped distribution nor a single-peaked distribution. This is also corroborated by the Graph of Temperature (°F) vs. Frequency in the attached excel file which shows that there are two peaks which are 2 and 14.
Therefore, the frequency distribution does NOT appear to have a normal distribution using a strict interpretation of the relevant criteria.
Ratio of the radii = sqrt16 / sqrt81 = 4/9
so radius of circle Q is found by solving 4/9 = 8/x where x = radius of Q
x = 2*9 = 18
radius of circle Q = 18.
Set the width to be x. Thus, the length is 4x.
The perimeter is 2(x+4x)=100, so x=10.
Plugging in x=10, you get that 4x=40.
So, the area of the rectangle is 400 
.
Because there are 100 centimeters in a meter and you are asking for area, you must multiply by 
to get 4000000 
.
