The ratio of a pair of corresponding sides of 1/16.
Answer:
<u>The correct answer is A. -1.69</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Mean of the popping time of the kernels in a brand of microwave popcorn = 150 seconds
Standard deviation of the popping time of the kernels in a brand of microwave popcorn = 13 seconds
Time that first kernel pops = 128 seconds
2. What is the z-score of this kernel? Round your answer to two decimal places.
z-score = (Time that first kernel pops - Mean of the popping time)/Standard deviation of the popping time
Replacing with the real values, we have:
z-score = (128 - 150)/13
z-score = -22/13
<u>z-score = - 1.69</u>
<u>The correct answer is A. -1.69</u>
The diameter of the table is 42 inches. The radius of the table is half of the diameter of the table, so the radius of the table is 42/2 = 21 inches.
Add on 8 inches to the table radius to get: 21+8 = 29
So the radius of the table cloth is r = 29
Plug this into the area of a circle formula
A = pi*r^2
A = pi*29^2
A = pi*841
A = 841pi
A = 841*3.14
A = 2640.74
The approximate area of the table cloth is 2640.74 square inches.
