Answer: 1/7

Step by step:

First divide the 1/49 to get 0.02040816326530612244897959183673 then take the square root of that number to get 0.14285714285714285714285714285714. Then plug in the numbers which after that your answer 0.14285714285714285714285714285714 or 1/7.

Hope this helps...

Have a great day.

Answer:

$s = 54m +160$

Step-by-step explanation:

Given: The attachment

Required: Determine the equation

We start by picking any two equivalent points on the table:

$(m_1,s_1) = (2,268)$

$(m_2,s_2) = (4,376)$

Next, we determine the slope, M:

$M = \frac{s_2 - s_1}{m_2 - m_1}$

$M = \frac{376 - 268}{4-2}$

$M = \frac{108}{2}$

$M = 54$

The equation is then calculated as:

$s - s_1 = M(m - m_1)$

Where:

$M = 54$

$(m_1,s_1) = (2,268)$

So, we have:

$s - 268 = 54(m - 2)$

Open bracket

$s - 268 = 54m - 108$

Collect like terms

$s = 54m - 108 + 268$

$s = 54m +160$

Hence, the equation is: $s = 54m +160$

A mechanic sells a brand of automobile tire that has a life expectancy that is normally distributed, with a mean life of 27 com

Harrizon [31]

Answer:

Tires that wear out by approximately 24307.8 miles will be replaces free of charge.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 27,000 miles

Standard Deviation, σ = 2100 miles

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

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.10

$P( X < x) = P( z < \displaystyle\frac{x - 27000}{2100})=0.10$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 27000}{2100} = -1.282\\\\x = 24307.8$

Tires that wear out by approximately 24307.8 miles will be replaces free of charge.
