Answer:
k = 9
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 8
m =
with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)
m = = k - 1 = 8 ( add 1 to both sides )
k = 9
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.
