S = (10 x1 /2) + (1/2x- 2x 1/2²)
5 + (-0.25)
= 4.75
Answer:
5
Step-by-step explanation:
4p-pq=4.5-3.5=20-15=5
Answer:
23
Step-by-step explanation:
So we are simply adding them
we will set the denominator equal by multiplying both the numerator and denominator
then just adding the numerator while keeping the denominator. look at my work. so your answer is 5/8
Answer:
p=0.063
Step-by-step explanation:
Let X be number of the certain brand of jelly beans that are made so that each package contains about the same number of beans.
X is N(375, 8)
YOu are collecting a sample size of
n = 8
Findings from the sample


(Left tailed test at 5% level)
Since sample size is small though sigma is known we use Z test, since norm
Mean difference = -5
Std error = 
Test statistic t = mean diference / std error = 
df = n-1 =5
p value = 0.063
