Answer:
The mean of W is 55 ounces.
The standard deviation of W is 4.33 ounces.
Step-by-step explanation:
Let X: weight of a red delicious apple, and B: the weight of the box and packing material.
The distribution that will represent W: the total weight of the packaged 5 randomly selected apples will be also normally distributed.
Applying the property of the mean:
, the mean of W will be:

Applying the property of the variance:
, the variance of W will be:

The mean standard deviation of W will be the squared root of V(W):

The mean of W is 55 ounces.
The standard deviation of W is 4.33 ounces.
Answer:
10(x-3)
Step-by-step explanation:
6/10 and 5/10
The common denominator is 10
Simplify it to 2x-4=8x-4
-6x=0
x=0
not sure if that counts as no solution or single solution though...
