Answer:
Her commute would be between 32 and 35 minutes 33 times.
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:

Proportion of days in which the commute is between 32 and 35 minutes:
This is the pvalue of Z when X = 35 subtracted by the pvalue of Z when X = 32.
X = 35



has a pvalue of 0.94.
X = 32



has a pvalue of 0.8133.
0.94 - 0.8133 = 0.1267
Out of 262 days:
Each day, 0.1267 probability
0.1267*262 = 33
Her commute would be between 32 and 35 minutes 33 times.
Answer:
2 x = 5 2x=5 2x=5. 2x=5. 2x=5. 2x=5. 1. Divide both sides by 2 2 2. x = 5 2 x=\frac{5}{2} x=25. Done. Decimal Form: 2.5. Check Answer ▽. x=5/2.
