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:
-3/4n +3/8
Step-by-step explanation:
1/4(−3n+3/2)
Distribute the 1/4
1/4*-3n + 1/4*3/2
-3/4n +3/8
We just need to solve the equation in order to find the value.
So we subtract 5 from both sides of the euqation and get
Now we divide by 3 on both sides and get
So the answer is C.
