If l and m are parallel find the value of each missing variable(s)
(8x-77)° (3x+38)°
the assignment is called parallel lines, transversals, and algebra plz

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

x = 3 ± √(5+y)

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
