BRAINLIEST PLS!!!
Answer:
0.898
Step-by-step explanation:
The formula for the Coefficient of determination = ratio of explained variation to Total variation
From the above question, we have the following values
Explained variation = 18.592
Total variation = 20.711
The coefficient of determination = 18.592 : 20.711
= 18.592/20.711
= 0.8976872194
Approximately ≈ 0.898
Therefore, the coefficient of determination is 0.898
The simple interest rate equation is I = Prt
I = interest
P = principle ($54,000)
r = rate (3.875%)
t = time (3 months, so .25 years)
I = Prt
I = (54,000)*(.03875)*(.25)
I = $523.125
I believe you should try to plug in the ordered pair to see if the solutions work.
The ordered pair is (x,y) because x is on the x-axis and y is on the y-axis, therefore in (16,-3) the x=16 and y=-3.
Now substitute, meaning plug in those numbers into the equation.
For x+2y=10 would be 16+2(-3)=10
Now you just need to solve one side and see if it equals the other side.
16+2(-3)
First you use order of operations to solve this. PEMDAS. So you multiply 2(-3) first because of the parenthesis and it being multiplication.
16+(-6) and when you have a positive number adding a negative number it’s going backwards of the number line, basically meaning subtraction in a way. Sorry if this confuses you, if you already know how to do negatives and such nevermind this part.
But 16+(-6)=10
So now you look at both side of the equation, does the left side equal to the right? 10=10, so yes. It is a solution for that equation.
Now for the next equation, 7y=-21
Again, plug in the ordered pair (16,-3) into the equation. Remember that it’s (x,y).
There is no x in this equation so no need to worry about that; you only plug in y for this one.
7(-3) Now you multiply. Whenever you multiply a positive number and a negative number, the answer will always be negative. So 7(-3) is -21.
Now look if the left side is equivalent to the right. Does -21=-21? Yes. The ordered pair is a solution.
(16,-3) is a solution to both equations.
Hope this helps!
