The number in parenthesis is the x value
F(2) means x equals 2
The letter would be A
Answer:
1. -1.25
2. 0.1056
Step-by-step explanation:
We are given that
mean=129
S.D=0.8
1.
The z-score can be found as
z=(x-mean)/S.D
z=(128-129)/0.8
z=-1/0.8
z=-1.25
Thus, a z-score corresponding to 128 fl. Oz. milk is -1.25.
2.
We have to find P(X<128).
A z-score is already found in part 1, So,
P(X<128)=P(Z<-1.25)
P(X<128)=P(-∞<Z<0)-P(0<Z<-1.25)
Using normal area table, we get P(0<Z<-1.25)=0.3944
P(X<128)=0.5-0.3944
P(X<128)=0.1056
Thus the probability that a randomly selected jug will contain less than 128 fl. Oz. of milk is 0.1056 or 10.56%

Step-by-step explanation:
{(-3, -3),(-6, -7), (6,-3), (–9, 2)} {(8,–8), (-9,5), (9,-2), (-2,-8)}
{(-7, -3), (-6, -1), (-6,8), (6, -6)}
