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.

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

hello from mrbilldoesmath!

answer:

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

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

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

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb
