Answer:
1 whole or 6/6
Step-by-step explanation:
Answer:
$21.85
Step-by-step explanation
the equation would be
4.95b+3.50c
b= the number of books (3)
c= the number of candles (2)
plug in the numbers
4.95(3)+3.50(2)=21.85
Answer:
P(x ≥ 30) = 0.3859
Step-by-step explanation:
When the distribution is normal, we use 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 question, we have that:

This probability is going to be 1 subtracted by the pvalue of Z when X = 30. So



has a pvalue of 0.6141
1 - 0.6141 = 0.3859
So
P(x ≥ 30) = 0.3859
