When the pandemic was over, Mrs. Patterson threw the bottle of bleach in the garbage. The bottle went 10 feet high and she was 1

Lera25 [3.4K]

Answer:

y = (5/8)x

Step-by-step explanation:

The bottle, ideally, went through a path of a line. Because she threw it upwards in a slant manner for it to have gotten to the garbage. The equation of a line is given as:

y = mx + c

We are given the vertical height as 10ft and horizontal height as 16ft.

m = vertical height/horizontal height

m = 10ft/16ft

m = 5/8

c is the y-intercept.

Since she is standing on the ground (origin) then the y intercept is 0.

The equation becomes

y = (5/8)x

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.
