Answer:
The degrees of freedom for the chi square statistic is 7-4=3
Answer: w=-6/14
Step-by-step explanation:
First you are going to put one equation on top of the other and subtract. Then you will use your new equation to combing like terms then divide your end result by your w value and make an improper fraction.
To find the x intercept just substitute your y value for 0 then solve for x.
So you get 0= x+3 and then you get x=-3 which is at (-3,0).
Step-by-step explanation:
The second one is the first claim, because it is a traingles and one square.
The third one is the sond claim because they are a part of the rectangular so moving them outside of it would increase the area, I think, if that makes sense.
Answer:8w^2+2
w(3w+2)+5w
First distribute the w to the parentheses:
3w^2+w
Add on the 5w to the new equation:
3w^2+2w+5w
Combine like terms:
8w^2+2
