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.
Answer:
Solution (-3, -5)
systems or linear equations
y = x - 2
y = 3x + 4
Step-by-step explanation:
-2,-2 ( 0,4
The answers checked for #1, #2, #4, and #5 are correct.
In #3, the constant factor is -3 . So the absolute value of
each term is 3 times the absolute value of the previous one,
AND the signs alternate.
Answer:
5
Step-by-step explanation:
-4 = x - 9 <em>add</em><em> </em><em>9</em>
5 = x
-4 = 5 - 9
Answer: in standerd form you need to solve 1 + 3 then 1 - 2
