Answer: The proportion that will qualify is 0.0314 or 3.14%.
First, we need to find the z-score of a time of 128 seconds. To do this, we find the difference of the mean and score and divide by the standard deviation.
(128 - 141) / 7 = -1.86
Now, use a standard normal distribution table to determine the percent below a z-score of -1.86. That value is 0.0314 or 3.14%.
Answer: 1,098.1

Answer:
-14
Step-by-step explanation:
-8(2)-[3(-5)-(-1)+4(2-6)]+4(-7)
opening the brackets
-8(2)-[-15+1+4(-4)]+4(-7)
-8(2)-[-15+1+4(-4)]+(-28)
-8(2)-[-15+1+(-16)]-28
-16-[-15+1+-16]-28
-16-[-15-16+1]-28
-16-[-31+1]-28
-16-[-30]-28
-16+30-28
-16-28+30
-44+30
-14
