Answer:
0.002
Step-by-step explanation:
We need to estimate the standard error of the mean, so we can use it as a standard deviation of the sample of 50 males.
Standard error of the mean = standard deviation/√n
Standard error of the mean = 32/√50 = 4.52
Now we can use this Standard error of the mean to estimate z as follows:
Z = (x – mean)/standard deviation
Z = (190-177)/4.52
Z = 2.87
Using a Z table we can find probability that mean is under 190
P (z<190)= 0.998
For the probability that the mean exceed 190 lbs we substract from 1
P(z>190) = 1 - 0.998 = 0.002
The answers are -16 and 9. Hopefully this helps :D
Answer:
More than means addition and product means multiplication. Therefore, seven more than the product of three and x would mean multiplying 3 and x together then adding 7 to that. Or, 3x + 7.

Answer: 5 2/3 inches
Step-by-step explanation:
From the question, we are informed that the scale drawing of an airplane is:
1 inch = 3 meters.
Since the length of the actual plane is 17 meters, the length of the plane in the scale drawing will then be:
= 17/3
= 5 2/3 inches
