uhm the answer is D. sorry if am wrong
Mean=total/the number of values =>total=mean*the number of values
the total of the first set of 8 numbers is : total=8*8=64
the total of the second set of 12 numbers is: 12m
the total of the 20 numbers is: 64+12m
the mean of the 20 number is: (64+12m)/20=5
solve for m: 64+12m=100
12m=36
m=3
See the attached picture:
6% = 1200
9% = 2400
12% = 3800
Answer:

Answer:
A:
The perimeter of the parking lot is 302 yards.
The area of the parking lot is 5,544 yards squared.
B: Perimeter
C: Area
Step-by-step explanation:
A:
To find the perimeter of the parking lot, we add all the sides up. 2L + 2W = Perimeter.
2(63) + 2 (88) = 302
To find the area, we multiply the length by the width. 63 × 88 = 5,544.
B: We need to know the amount of chain needed to surround the parking lot. In other words, we need to line the perimeter with a chain.
C: We would be paving the entire area of the parking lot.
