100 pionts PLEASE HELP ME I DONT HAVE THE GRAPH BUT ITS EDGE 2020 Step 2: Evaluating trends of data

Because you want to prepare and serve the healthiest food possible, you monitor the fat and calorie content of items on your menu. Some of the menu items are included in the graph below.

a) Your business partner describes this as a high positive correlation. Is your partner correct? Why or why not?

b) Using the drawing tools, draw a trend line (line of best fit) on the graph above.

c) Judge the closeness of your trend line to the data points. Do you notice a relationship between the data points?

d) Is the trend line linear? If so, write a linear equation that represents the trend line. Show your work.

sorry i have bad wifi but the answer is

Step-by-step explanation:

A. your partner is correct, even though fat is bad, the line does move up. If this were a profit graph it would make more sense.

B. Yes do see a relationship. This line move one direction up. notice how the dots move up like an escalator.

C.  This is a linear trend because it moves in a  line going up at a predictable rate. i cant show how though.

I dont reallly know

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

you,

mrb

(a + b) (a^2 - a b + b^2)
