The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000 miles and a standard deviation of 1500 miles. What is the probability a certain tire of this brand will last between 56,850 miles and 57,300 miles

0.018 is the required probability.              

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 60,000 miles

Standard Deviation, σ = 1500 miles

We are given that the distribution of tread life is a bell shaped distribution that is a normal distribution.

Formula:

P(brand will last between 56,850 miles and 57,300 miles)

0.018 is the probability a certain tire of this brand will last between 56,850 miles and 57,300 miles.

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
