Answer:
std dev = 0.625
Step-by-step explanation:
Given that weights of bags of potato chips coming from a factory follow a normal distribution with mean 12.8 ounces and standard deviation .6 ounces.
We must change std deviation such that
P(X<12) =0.01
Mean would remain the same as 12.8 oz
From normal distribution score we can find
10th percentile is -1.28\
i.e. we must have
Std deviation should be 0.625
Step-by-step explanation:
3h - 10 = 35 ➡ 3h = 35 + 10 ➡ 3h = 45 ➡h = 15
We know how wide the billboard will be. Therefore, to know how much the original image should be enlarged, you have to divide the final width of the billboard between the current width of the invoice.
Therefore the correct answer is option D.
In order for the bill to cover the billboard, the bill must be expanded by a factor of 7.81 feet in length by inch in length.
The inequality could be 82=14+4h with h standing in for hours worked
It would be 3 in by 4 in because you would divide the number of feet by 6.
