What type of correlation is shown in the graph ? positive no correlation linear negative

Leokris [45]

Answer:

y=-23/6

Step-by-step explanation:

in the equation, you would need to first subtract y and -2y which equals -y=> (this would be on the left side of the equation)

then, subtract -1/2 on both sides of equation and put that in the right side of the equation.

add 1/3 on both sides of equation and put that in the right side of equation as well.

now, you have this equation: -y=4-1/2+1/3

you have to make all the fractions have the same denominator by multiplying which results for 4 to be 24/6, -1/2 to be -3/6, and 1/3 to be 2/6

your resulting equation would be -y=24/6-3/6+2/6

and when you solve the right side of the equation by subtracting and adding, you get 23/6

now, the equation would be -y=23/6

finally, you just have to divide -1 on both sides of the equation and you would get y=-23/6 as your final solution.

I hope that helps :)

A real estate agent has surveyed houses in twenty nearby zip codes in an attempt to put together a comparison for a new property

gladu [14]

Answer:

A a house in that market that sells for $300,000 is unusual.

Step-by-step explanation:

Let the random variable X denote the price of a house and the random variable Y denote the living area of a house.

The number of houses surveyed by the real estate agent is, n = 1057.

Assume that both the random variables, X and Y are approximately normally distributed.

That is,

$X\sim N(\$169400,\ \$68438)\\\\Y\sim N(2058\ \text{sq. ft.},\ 790\ \text{sq. ft.})$

To compute the probability of a Normal distribution we first need to convert the raw scores to z-scores.

$z=\frac{\text{Raw score}-\mu}{\sigma}$

A z-score higher than 1.96 and lower than -1.96 are considered unusual. The values having these z-scores are considered as outliers.

(1)

Compute the z-score for X = 300000 as follows:

$z=\frac{X-\mu}{\sigma}\\\\=\frac{300000-169400}{68438}\\\\=2.70$

(2)

Compute the z-score for Y = 3000 as follows:

$z=\frac{Y-\mu}{\sigma}\\\\=\frac{3000-2058}{790}\\\\=1.19$

The z-score for a house in that market that sells for $300,000 is more than 1.96.

This implies, that the price $300,000 is unusually high.

The complete statement is:

The house that sells for $300 comma 000 has a z-score of 2.70 and the house with 3000 sq ft has a z-score of 1.19.
