X - y = 9
x + 2y = 27
You can subtract the top equation from the bottom
3y = 18
y = 6
x = 15
The two numbers are 15 and 6
Answer: 3
Step-by-step explanation:
3(-1)^2
You need to contact the app about that, try maybe their customer service or their email?
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>
