Answer:
2.28% probability that a randomly selected Tesla model 3 can travel more than 310 miles
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 randomly selected Tesla model 3 can travel more than 310 miles?
This is 1 subtracted by the pvalue of Z when X = 310. So



has a pvalue of 0.0228
2.28% probability that a randomly selected Tesla model 3 can travel more than 310 miles
Answer:
Step-by-step explanation:
The book shelf arrived at the wholesale price = $ 147
Mark up on the furniture = 60 %
So The Cost Price = $147
Markup = 60% = 0.60
So using the formula
Sale Price = Cost Price + Cost Price * Markup percentage
So
Sale Price = 147 + 147*(0.60)
Sale Price = $ 235.20
