Step-by-step explanation:
Answer:
a = 33.32
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

P(32 < x < a) = .0590
This is the pvalue of Z when X = a subtracted by the pvalue of Z when X = 32.
X = 32



has a pvalue of 0.1587
X = a
p - 0.1587 = 0.0590
p = 0.0590 + 0.1587
p = 0.2177
So when X = a, Z has a pvalue of 0.2177. So when X = a, Z = -0.78.




So a = 33.32
He would spend $27.50, because each bag costs $5.50. Multiply that by 5 and you have your answer :)
3m - 5m - 12 = 7m - 88 - 5
-2m - 12 = 7m - 88 - 5
-2m - 12 = 7m - 93
-12 = 7m - 93 + 2m
-12 = 9m - 93
-12 + 93 = 9m
81 = 9m
9 = m
hope that helps, God bless!
