I pretty sure you either add or subtract to get the answer
Answer:
Longe and glirt
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have that the <span>data set has SSR=400 and SSE=100
2. Therefore you have </span><span>the coefficient of determination is:
r</span>²=SSR/SSTO
SSTO=SSR+SSE
3. Then, when you substitute the values, you obtain:
SSTO=400+100
SSTO=500
r²=400/500
4. So, you have that the result is:
r²=0.8
Therefore, as you can see, the answer for the exercise shown above is: <span> the coefficient of determination is 0.8</span>
Length is increased so the new length would be 1.1L
The width is decreased by p percent, which now becomes 1-P/100
The new area = 1.1l x (1-P/100)
The area decreases by 12 percent, so the new area = 0.88A
Noe you have 0.88A = 1.1L * (1-P/100)
Simplify to get 0.8 = 1-P/100
Solve for P to get 0.2
Multiply by 100 for the percent: 20%
The answer is C.
