Answer:
57.93% probability that a trip will take at least 35 minutes.
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 is the probability that a trip will take at least 35 minutes
This probability is 1 subtracted by the pvalue of Z when X = 35. So



has a pvalue of 0.4207
1 - 0.4207 = 0.5793
57.93% probability that a trip will take at least 35 minutes.

Answer:
Computing the sum of $5.89 and $1.45 we get: $7.34
Step-by-step explanation:
We need to explain, how can we compute the sum of $5.89 and $1.45?
Computing the sums of dollar amounts is same as computing the sum of simple decimal expressions. Each value will be added to its corresponding values and we will get the answer.
Computing the sum of $5.89 and $1.45

So, we will start adding from right side, 9 will be added with 5 and we get 14, 1 will be given carry and 8 will be added by 4 and add the carry we get 13, 1 will be given carry and 1 will be added by 5 and add the carry we get 7
So, Computing the sum of $5.89 and $1.45 we get: $7.34
