Answer:

-\frac{5}{7}

Step-by-step explanation:

Slope = \frac{rise}{run}

          = \frac{6-11}{5-(-2)}

          = \frac{6-11}{5+2}

          = \frac{-5}{7}

          = -\frac{5}{7}

Answer:

To calculate the slope, you can first substract the points to get the vector that join both, you may do it like this:

(-2, 11) - (5,6) = (-2 - 5, 11 - 6) = (-7, 5)

To get the slope when you get the vector (x,y), you will have to divide y be x:

5/-7

So the slope is 5/-7, -\frac{5}{7}

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 <em>X</em> denote the price of a house and the random variable <em>Y</em> denote the living area of a house.

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

Assume that both the random  variables, <em>X </em>and <em>Y</em> 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 <em>z</em>-scores.

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

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

(1)

Compute the <em>z</em>-score for <em>X</em> = 300000 as follows:

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

(2)

Compute the <em>z</em>-score for <em>Y</em> = 3000 as follows:

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

The <em>z</em>-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 <u>2.70</u> and the house with 3000 sq ft has a​ z-score of <u>1.19</u>.

In the triangle above, what is sin A
Shkiper50 [21]

Answer:

\large\boxed{\sf sin(A)=0.5}

Step-by-step explanation:

A right angled triangle is given to us and we would like to find out the value of sin(A) .

From the triangle we can see that the measure of angle BAC is 30° . Therefore ,

\longrightarrow A = 30^o

On using sin both sides ,

\longrightarrow sin(A) = sin30^o

As we know that the value of sin30° = 1/2. So;

\longrightarrow sin(A)=\dfrac{1}{2}

Simplify by converting it into decimal ,

\longrightarrow \underline{\underline{sin(A) = 0.5}}

<u>Hence</u><u> </u><u>option</u><u> </u><u>B</u><u> </u><u>is</u><u> </u><u>correct</u><u> </u><u>.</u>

And we are done!
