Will give brainliest if both are correct

these are two separate questions that have nothing to do with each other.

find the constant of variation k for the direct variation.

x | f(x)

-1 | 2

0 | 0

2 | -4

5 | -10

a) k = –0.5

b) k = 2

c) k = –1.5

d) k = –2

question 2

does the data in the table represent a direct variation or an inverse variation? write an equation to model the data in the table.

|_2__|__4__|__8__|__12__|

|_4__||__1__|__2/3_|

direct variation; y = 8/x

direct variation; y = 8x

inverse variation; xy = 8

inverse variation; y/x = 8

Astudy was interested in determining if eating milk chocolate lowered someone's cholesterol levels. ten people's cholesterol was measured. then, each of these individuals were told to eat 100g of milk chocolate every day and to eat as they normally did. after two weeks, their cholesterol levels were measured again. is there evidence to support that their cholesterol levels went down? how should we write the alternative hypothesis? (mud = the population mean difference= before - after)a. ha: mud = 0b. ha: mud > 0c. ha: mud < 0d. ha: mud does not equal 0
