Answer:
6 hours
Step-by-step explanation:
180 divided by 30 = 6
3.5 : 5
7 : 10
14 : 20
17.5 : 25
At that rate, she can read 17.5 pages in 25 minuets.
Divide both 7 and 10 by 2, which gets 3.5 and 5
5 * 5 = 25
5 * 3.5 = 17.5
Therefore, in 25 minuets, she can read 17.5 pages.
Answer:
99.89% of students scored below 95 points.
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:

What percent of students scored below 95 points?
This is the pvalue of Z when X = 95. So



has a pvalue of 0.9989.
99.89% of students scored below 95 points.
