Answer:
A. 18.4
Step-by-step explanation:
The mean is the average. In order to find the answer you must add all the values of the variables and divide them by the number of variables. Simply just add 14, 15, 18, 20, and 25, and then divide it by 5 (the number of variables). Then you get your answer.
14+15+18+20+25=92
92/5=18.4
A. 18.4
Answer:
16 and 25
Step-by-step explanation:
The area of the poster is B. 535.5 in².
Step-by-step explanation:
Step 1:
The poster consists of a rectangle and three-quarters of a circle.
The rectangle has a length of a and width of 3a. The circle has a radius of a.
We calculate the areas of the individual shapes and sum them up to calculate the entire area of the poster.
Step 2:
The area of a rectangle is the product of its length and its width.
If a = 10 inches, the length is 10 inches and the width is 30 inches.
The area of the rectangle 
The area of the rectangle is 300 in².
Step 3:
The area of a circle
Here we only have three-quarters of a circle, so
The area of the given circle 
Here r = a = 10 inches.
So the area of the circle 
The area of the circle is 235.6125 in².
Step 4:
The total area of the shape = The area of the rectangle + The area of the circle.
The total area of the shape 
So the area of the poster is B. 535.5 in².
