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%
Answer:
-16
Step-by-step explanation:
-a/3 >5,,,, a/3 < - 5,,,,,, a< - 15 hence a should be - 16
Since they’re in the same place you would do for 4 X -3 equals 115 and take it from there then you would find your answer and you may have to subtract it by 180
