1 pts Given the following pairs of data (independent variable given first): (186, 1),(175, 10), (112, 100), (95, 250), (82, 800), (60, 1000). The regression line is:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

answer: -8.2562234e+13

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

it would open into a square depending on the type of envelope i’m not sure about the second part
