Ahigh school administrator determined that 22% of the students worked part-time after school with an latex: \pm±8% margin of error. if the school has 1420 students, which would represent the possible number of students that work part-time after school?

199 to 426 students.

Step-by-step explanation:

.22 + .8 = .3

.22 - .8 = .14

1420 * .3 = 426 <- Max possible

1420 * .14 = 199 <- Min possible

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y
