Question: consider a large number of countries around the world. There is a positive correlation between the number of laptops per 1000 people (x) and the average life expectancy y. Does this mean that we could increase the Life expectancy and Rwanda by shipping laptops to that country?/answer your options are in picture please help!!!

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.

15.36 per mile

but forgot to round

i am pretty sure
