Answer:
y=-3
Step-by-step explanation:
-2(-25)+2y=44
Substitute -25 for x
Then multiply
50+2y=44
-50 -50
Subtract 50 on both sides
2y/2=-6/2
Divide 2 and 6
Answer is -3
Answer:
<h2>0.7</h2>
Step-by-step explanation:
The coefficient of determination which is also known as the R² value is expressed as shown;

Sum of square of total (SST)= sum of square of error (SSE )+ sum of square of regression (SSR)
Given SSE = 60 and SSR = 140
SST = 60 + 140
SST = 200
Since R² = SSR/SST
R² = 140/200
R² = 0.7
Hence, the coefficient of determination is 0.7. Note that the coefficient of determination always lies between 0 and 1.
Answer:
You know that 1 mile = 5280 feet and 1 foot = 12 inches, so using these conversion factors you can go from one to the other.
I hope this answered you question!
Step-by-step explanation:
Answer:
y= -3+7x
Step-by-step explanation:
7x-y=3 for y
Move variable to the right
-y+3-7x
Change the signs
y= -3+7x
In this situation I would use cosine to find m∠G.
Cosine = Adjacent side ÷ Hypotenuse
RG being the adjacent side and TG being the hypotenuse, you would set up the equation like this
cos(g) = 8/17
then solve
cos(g) = 0.47058
simplify
g = cos^-1(0.47058)
and you get
m∠G = 61.9°
So your answer would be 62°
