Answer:
P= 3
Q= -14
R= -5
Step-by-step explanation:
Just solve the equation on the right side, you'll get:
=3x^2 -15x +x -5
=3x^2 -14x -5
Now compare it to the equation on the left side,
The coefficient of x^2 on the left is "p", on the right that we just solved is 3.
Same for "q" which is the coefficient on the left, on the right it's -14.
And for "r" it's -5 from the equation on the right.

Answer:
D
Step-by-step explanation:
Hello there! As far as we can see, the y-intercept is 2. Going up 2 helps move the line up by 2. We can go ahead and eliminate C, because that equation only goes up one, and D, because we don't go down any. We have the points (1, 3) and (2, 4). We add the x-value and we can see that 1 + 2 is 3 and 2 + 2 is 4. The only equation that fits the line at all is A. Therefore, the answer is A.
Answer:
0.67; The least-squares regression line, given by ŷ = 3.95 + 0.67x, is not a good fit for the data.
Step-by-step explanation:
Plot the data in a spreadsheet and insert a trendline. The line of best fit is y = 0.67x + 3.95. The r² value is 0.67.
