The box plot shows the number of years during which 24 colleges have participated in a local college fair: A boxplot is titled Years of Participation and labeled Years. Number line from 0 to 10 with primary markings and labels at 0, 5, and 10. The box extends from 2 to 7 on the number line. There is a vertical line at 4. The whiskers end at 0 and 9. At least how many schools have participated for 2 years or fewer? 2 schools 4 schools 6 schools 7 schools

step-by-step explanation:

the formula of a midpoint between a abd b:

a

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a

the answer should be 3.54 g/cm^3
