2 answers:
Answer: Each friend will get 0.527 pound of grapes.
Step-by-step explanation:
We are given that Joe bought 5.8 pounds of grapes to have as a snack with his 10 friends.
Total persons including Joe = 10+1= 11
If he shares his grapes evenly, then by division operation , we have
Number of pounds of grapes will each of his friends get will be
pounds
Therefore, each friend will get 0.527 pounds of grapes.

Answer:
Probability that deliberation will last between 12 and 15 hours is 0.1725.
Step-by-step explanation:
We are given that a recent study showed that the length of time that juries deliberate on a verdict for civil trials is normally distributed with a mean equal to 12.56 hours with a standard deviation of 6.7 hours.
<em>Let X = length of time that juries deliberate on a verdict for civil trials</em>
So, X ~ N()
The z score probability distribution is given by;
Z = ~ N(0,1)
where, = mean time = 12.56 hours
= standard deviation = 6.7 hours
So, Probability that deliberation will last between 12 and 15 hours is given by = P(12 hours < X < 15 hours) = P(X < 15) - P(X 12)
P(X < 15) = P( <
) = P(Z < 0.36) = 0.64058
P(X 12) = P(
) = P(Z
-0.08) = 1 - P(Z < 0.08)
= 1 - 0.53188 = 0.46812
<em>Therefore, P(12 hours < X < 15 hours) = 0.64058 - 0.46812 = 0.1725</em>
Hence, probability that deliberation will last between 12 and 15 hours is 0.1725.
