we know that

The correlation coefficient is a number between -1 and +1 that represent the linear dependence of two variables or sets of data

Using a Excel tool (CORREL function)

see the attached table

the correlation coefficient is  r=1

therefore

<u>the answer is    </u>

r=1

The table represents a linear function. Find the values of A and B.​
bazaltina [42]

Answer:

The answers are that a = -5 and b = 1

Step-by-step explanation:

In order to find A and B, we first need to find the equation of the line. We can do this by using two ordered pairs and the slope formula. For the purpose of this activity, I'l use (0, 5) and (-3, 11)

m(slope) = (y2 - y1)/(x2 - x1)

m = (11 - 5)/(-3 - 0)

m = 6/-3

m = -2

Now that we have this we can model this using point-slope form.

y - y1 = m(x - x1)

y - 5 = -2(x - 0)

y - 5 = -2x

y = -2x + 5

Now that we have the modeled equation we can use the ordered pair (a, 15) to solve for a.

y = -2x + 5

15 = -2(a) + 5

10 = -2a

-5 = a

And we can also solve for b using the ordered pair (2, b)

y = -2x + 5

b = -2(2) + 5

b = -4 + 5

b = 1

Corinne has a job selling magazines. She earns $7.50 per hour plus 20% of the total amount of her sales. She also gets an allowa
maw [93]
PART A
Coefficient
Coefficient h is 7.50
Coefficient s is 0.20

Variable
h and s

Constant
40

PART B
7.50h + 0.20s + 40
= 7.50(25) + 0.20(300) + 40
= 187.5 + 60 + 40
= 287.5
She earns $287.5

PART C
Yes, the coefficient of h would change to 9, the rests are still the same. Because she's no longer receive 7.50 per hour, and start earning 9 per hour, so the coefficient should change.
The expression would be
9h + 0.20s + 40

PLSS HELPP BRAINLIEST AND 65 POINTS <br> pls do the graph too
Eddi Din [679]

Answer:

\Large \boxed{ -x+65}

Step-by-step explanation:

Two points are (0, 65) and (10, 55)

Calculate slope <em>m</em>

\displaystyle m=\frac{y_2 - y_1}{x_2 - x_1}

\displaystyle m=\frac{55-65}{10-0}=-1

Use slope-intercept form

y=mx+b

y=-1x+b

<em>b</em>  is the y-intercept, y-intercept is (0,65)

y=-1x+65
