Elena collects data to investigate the relationship between the number of bananas she buys at the store (LaTeX: xx) and the total cost of the bananas (LaTeX: yy). Which value for the correlation coefficient is most likely to match a line of best fit of the form LaTeX: y=mx+by = m x + b for this situation?
r=–0.9

r=–0.4

r=0.9

r=0.4

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )
