A bag contains 8 green marbles and 40 yellow marbles. If a representative sample contains 3 green marbles, then how many yellow marbles would you expect it to contain? Explain.
Because the ratio of green marbles to yellow marbles is in the population, the expected
number of yellow marbles is times the number of green marbles in the representative sample.
There should be yellow marbles.

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
