Answer:
Standard deviation of the length of granola bars produced at Bernie's Bars is 0.50
Step-by-step explanation:
We are given the following information in the question:
Formula:
where,
μ is the mean and σ is the standard deviation.
Putting the values we get:
Solving the two obtained equations:
Subtracting the two obtained equation, we have:
Hence, standard deviation of the length of granola bars produced at Bernie's Bars is 0.50
P(s) = 45/125 = 0.360
P(A&C) = 38/125 = 0.304
Probability that one is not in Arts and Crafts = 1- P(A&C) = 1-0.304 = 0.696
Therefore,
Probability that the child selected is in swimming when its known they didn't sign for Arts and craft = Probability they signed for swimming * Probability that they didn't sign for Arts and Crafts = 0.360*0.696 = 0.25056
Answer:
-28
Step-by-step explanation:
4 2/3=14/3
-6(14/3)=-2*14=-28
X= 36 I think
