A manufacturer of tires wants to advertise a mileage interval that ex-cludes no more than 10% of the mileage on tires he sells.
Sergio039 [100]

Answer:

This mileage interval is from 30120 miles and higher.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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:

All he knows is that, for a large number of tires tested, the mean mileage was 25,000 miles, and the standard deviation was 4000 miles. This means that \mu = 25000, \sigma = 4000.

A manufacturer of tires wants to advertise a mileage interval that ex-cludes no more than 10% of the mileage on tires he sells. What interval wouldyou suggest?

The lower end of this interval is X when Z has a pvalue of 0.90.  That is Z = 1.28.

So

Z = \frac{X - \mu}{\sigma}

1.28 = \frac{X - 25000}{4000}

X - 25000 = 4000*1.28

X = 30120

This mileage interval is from 30120 miles and higher.

Jessica must plant 351 trees. In the past 6 days Jessica planted 234 trees. If she continues at this rate how many more days wil
OLga [1]

234 trees in 6 days so you divide 234 by 6 (39) so she plants 39 each day. Now you divide 351 by 39 (9) so at that rate it'll take 9 days in total and 6 days have already passed. So, 3 more days.
