Answer:
$24.5
Step-by-step explanation:
Given that:
cost of 8 books = 19.60$
So the cost of one will be found by:
cost of 1 book = 19.60$/8
cost of 1 book = $2.45
Now finding cost of 10 books:
cost of 10 books = $2.45 *10
cost of 10 books = $24.5

Answer:
The probability is 0.5438
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:
a. If 1 candy is randomly selected, find the probability that it weighs more than 0.8542g.
This is 1 subtracted by the pvalue of Z when X = 0.8542. So
has a pvalue of 0.4562
1 - 0.4562 = 0.5438
The probability is 0.5438
