Answer for the question No.17
Given:-
Let,
In quadrilateral ABCD,
---(sum of angle of quadrilateral is 360 degree)
SInce x=
The residual is -1.5 so the answer is a
The expected value is 8.5 when you plug 4 into the equation
Residual=observed-expected=7-8.5=-1.5
Let's find out.
David needs to score an average of 145 across all four games, so first we do:
145 × 4 = 580
Then we add all the scores he currently has:
139 + 143 + 144 = 426
Then we subtract 426 from 580 to find out how much he needs to score for his fourth:
580 - 426 = 154
David needs to score 154 on his 4th game to have an average score of 145 for all 4 games.
If by function form you're referencing a y= equation then this is how you do it.
You want the y variable to be alone on its own side, so our first step is to subtract that ugly 5x from the left side.
That gives you -y=-5x-1
Now, we never want the y to be negative so we fix this by multiplying both sides by negative one which will cancel out that negative.
We are then left with y=5x+1
It’s 11 i think. i’m not positive but i think that’s it.
