Answer:
They spend at least 69.48 minutes reading the paper.
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:

For the 10% who spend the most time reading the paper, how much time do they spend?
They spend at least X minutes, in which X is the value of X when Z has a pvalue of 0.90. So it is X when Z = 1.28.

Answer:
116
Step-by-step explanation:
348 divided by 3 equals 116
The domain is all real numbers and the range is all positive numbers.
The absolute parent function is f(x)=|x|.
The domain, or values of x, can be any real number. There is no x that will not give an answer in this function.
The range, or values of y, must be negative numbers. This is because the absolute value function makes values positive, since they are distance from 0.
