Answer: Jose traveled 3 miles on his bike before it broke down.
Step-by-step explanation:
Given : Jose wanted to ride his bicycle for a distance = 12 miles
Cycle broke down after he went only 25% of his distance i.e =
Thus Jose travelled for 3 miles before his bike broke down and he still has (12-3)= 9 miles of his distance to cover.
Thus Jose traveled 3 miles on his bike before it broke down.

Answer:
182.41
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:
40th percentile
Value of X when Z has a pvalue of 0.4. So X when Z = -0.253.
So the answer is 182.41.
