In a volatile housing market, the overall value of a home can be modeled by V(x)=325x2-4600x+145000, where V represents the valu

shtirl [24]

Answer:

The vertex of the given equation is which shows that the value of the market after about 5 years is about 187,253.01

Functions and values

Given the overall value of a home can be modeled by

V(x) = 415x^2 – 4600x + 200000

Write in vertex form to have:

V(x) = 415x^2 – 4600x + 200000

For the given equation, the vertex occur at

Hence the vertex of the given equation is which shows that the value of the market after about 5 years is about 187,253.01

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.

Someone help??????????????

I: x-2y>=8
II:2x+y<=3

start by isolating y on a side

with I:
x-2y>=8
-2y>=8-x
2y<=x-8
y<=x/2-4

with II:
2x+y<=3
y<=-2x+3

now you can draw I' and II' and read of the solutions with the graph.
transform the inequalities into lines in slope intercept form by replacing the inequality with equality:
y<=x/2-4
->
y=x/2-4

y<=-2x+3
->
y=-2x+3

look at the inequalities to figure out if the area above or below is valid for each line (y<=... -> area below is valid->colored in the attached image)
the area in which all areas overlap is the solution space.
