The IQ score and brain volume are listed for each of five different subjects. Refer to the table of measurements below. Given that the data are matched and considering the units of the​ data, does it make sense to use the difference between each IQ score and brain volume that is in the same​ column? Why or why​ not?

idk lol xd

step-by-step explanation:

ez do it yourself lazy

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

answer:

c) the x-coordinate of the center of the circle increases by 3
