Elena collects data to investigate the relationship between the number of bananas she buys at the store, ?, and the total cost of the bananas, ?. Which value for the correlation coefficient is most likely to match a line of best fit of the form ? = ?+? for this situation

30

step-by-step explanation:

idk

i hope i

Number 40 is a rational number glad i could

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

 

let x = 1st integer

let y = 2nd integer

 

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

 

substitute 3y+17 in place of x n equation 2

and solve for y.

 

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

 

from quadratic equation:

 

y = [-17±√(172-4(3)(24))]/(2(3))

 

y = (-17 ±√1)/6

 

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

 

since we are dealing with

y = -3

 

x = 3y+17 = -9+17 = 8

 

the integers are -3, 8
