<span>The mean for both processes is 28+17 = 45 minutes.
The variance is additive, so the total variance is 5+4 = 9. The standard deviation is the square root of variance, which is 3 minutes.
Then the z-score associated with a time of x = 50 minutes is:
z = (x - mean)/SD = (50 - 45)/3 = 1.67
From a z-table, the probability that (z > 1.67) is 0.0475.

Answer:
1 1/12
Step-by-step explanation:
3/4 x 3/3
1/3x4/4
9/12+4/12=13/12
The fraction 13/12 Cannot be reduced, But the fraction 13/12 is the same as 13 divided by 12
So 13/12=1 1/12
Therefore 3/4+1/3=1 1/12
Slope is 7/3 and y intercept is -3.
Answer:
Step-by-step explanation:
Given data
Profit from apple= $0.4
Profit from banana= $0.4
Let the number of Apples sold be x, and the number of bananas sold be y
and the total profit be P
Hence the expression for the total profit is given as
