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>
Answer: x=2 Please mark as brainliest
Step-by-step explanation: 16+7+4x=x+3x+7
combine like terms: 23+4x=4x+7
get x to one side: 23=8x+7
subtract: 16=8x
divide: x=2
