Answer:
C: f(x) = -½x + 4
Step-by-step explanation:
Using slope formula between 2 points, we know that;
slope; m = (y2 - y1)/(x2 - x1)
Let's consider 2 points from the table;
(0, 4) and (-4, 6)
Thus;
m = (6 - 4)/(-4 - 0)
m = 2/-4
m = -½
Now using slope intercept form equation which is y - y1 = m(x - x1), we can find the equation of the function by picking on point say (0, 4).
Thus;
y - 4 = -½(x - 0)
y - 4 = -½x
y = -½x + 4
Thus;
f(x) = -½x + 4
Answer:
The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:
Yes, the points are in a curved pattern.
Step-by-step explanation:
The correct formula for the residuals is given by:
Who represent the observed value minus the predicted. We can find the individual residuals and we got:
The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:
Yes, the points are in a curved pattern.
Answer:
Step-by-step explanation:
<u>Key skills needed: Exponent multiplication, Multiplication</u>
1) We have the expression -->
2) We have to simplify this (the parentheses mean multiplication)
The easiest thing to do is: Multiply 4 and 6 --> 4 x 6 = 24.
3) With the step above, the expression now would be .
We now have to do ×
For this we have to use this exponent rule --> ×
=
.
4) This means that ×
=
5) So the simplified expression would be -->
