Answer:
x=55
Step-by-step explanation:
2x-7=103
2x=103+7
2x=110
x=55
Answer:
Step-by-step explanation:
Okay this is an odd question, but what i'm thinking is that
first you have
5x+5
To actually be able to solve we have to move the 5 to the other side.
To do this we subtract it.
Making the equation
5x = -5
Then you need to isolate the variable (X)
So divide 5X by 5, and then divide -5/5
Which leaves you with:
x=-1
Answer:
-71
Step-by-step explanation:
let 'n' = a number
2(143 + 2n) = 0n + 2
2(143 + 2n) = 2
143 + 2n = 1
2n = -142
n = -71
Answer:
(a) The average grade point is 2.5.
(b) The relative frequency table is show below.
(c) The mean of the relative frequency distribution is 0.3333.
Step-by-step explanation:
The given data set is
4, 4, 4, 3, 3, 3, 1, 1, 1, 1
(a)
The average grade point is



Therefore the average grade point is 2.5.
(b)

The relative frequency table is show below:
x f Relative frequency
4 3 
3 3
1 4 
(c)
Mean of the relative frequency distribution is


Therefore the mean of the relative frequency distribution is 0.3333.
