Answer:
Option 3: mean increases by 3
Step-by-step explanation:
Current mean:
[50+76+78+2(79)+80+81+2(82)+83] ÷ 10
= 77
Without the outliers:
[76+78+2(79)+80+81+2(82)+83] ÷ 9
= 80
80 - 77 = 3 (increase)

Answer:
JL = 62
Step-by-step explanation:
JL = JK + KL, substitute values
5x + 2 = 27 + 3x - 1
5x + 2 = 26 + 3x ( subtract 3x from both sides )
2x + 2 = 26 ( subtract 2 from both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Thus
JL = 5x + 2 = 5(12) + 2 = 60 + 2 = 62
