Answer:

strong negative linear correlation
-0.986

Step-by-step explanation:

You need to notice that when altitude goes up, temperature goes down. That means the correlation is negative.

The table shows the temperature decrease to be monotonic (nowhere does it go up when altitude increases), so the correlation is strong.

The strong negative correlation number available to you is -0.986.

___

If you want confirmation, you can put the numbers into your favorite graphing calculator and tell it to compute the correlation for you.

<h3>System of equation</h3>

They consists of equations and unknown variables

Let the number of PCs be x

Let the number of Mac be y

If Mke has 12 computers, then;

x + y = 12

If there are two Macs for every PC in his classroom, then;

y = 2x

Substitute

x + 2x = 12

3x = 12

x = 4

Recall y = 2x

y = 2(4)

y = 8

There are 4 PCs and 8 Mac in the room

A plane is 24,000 feet above sea

IrinaVladis [17]

Answer:

A. -500

Step-by-step explanation:

Find the slope using rise over run (change in y / change in x)

Find the change in the y values (height of the plane):

24,000 - 18,000

= 6,000

Find the change in the x values (miles from the airport)

(60 - 72)

= -12

Divide 6000 by -12:

6000/-12

= -500

So, the slope of the plane's path is A. -500

A bus driver started her day with an empty bus. At her first stop she picked up

lidiya [134]

Answer:

12 people.

Step-by-step explanation:

Let's do this one at a time.

First stop:

0 + 11 = 11

Second stop:

11 + 5 = 16.

16 - 7 = 9.

Third stop:

9 + 5 = 14.

14 - 2 = 12.

There were 12 people on the bus after the driver left the third stop.

Write a equation of the lines passes through the given points (-2,7) (1,1) the equation is?

vredina [299]

The point-slope form:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-2, 7) and (1, 1). Substitute:

$m=\dfrac{1-7}{1-(-2)}=\dfrac{-6}{3}=-2$

$y-7=-2(x-(-2))\\\\\boxed{y-7=-2(x+2)}$ point-slope form

$\boxed{y=-2x+3}$ slope-intercept form

$\boxed{2x+y=3}$ standard form
