Answer:
$45.25
Step-by-step explanation:
The answer you got was correct.
In 4 months the temperature will be 3.2°C
The equation to get the answer would be 6.4×2.5
then, you get that answer (which is 9.6) and subtract the original 6.4 degrees
Answer:
Step-by-step explanation:
Given
Regression Equation:
Required
Determine the slope of the regression line
The equation of regression is of the form
Where b represents the slope;
Compare to the given equation
We have that:
Hence; the slope is:
To be able to solve clearly this problem, the best thing
to do is to plot the graph (see attached pic). From the graph we can see that
the points form a trapezoid.
The base is formed by the segment connecting point A and
point B.
While the two heights: shorter one by the segment
connecting points A and D, and the longer one by the segment connecting points
B and C.
The formula for area of trapezoid is given as:
A = b (h1 + h2) / 2
Where,
<span>b = base of the trapezoid
= 3 – (-4) = 7</span>
h1 = shorter height = 2 – (-2) = 4
h2 = longer height = 2 – (-5) = 7
Therefore the area is:
A = 7 (4 + 7) / 2
A = 77 / 2
<span>A = 38.5 </span>
Are you asking to simplify this: 5x(3 x 26)
If you are then:
5x(3 x 26)
= 15x x 130x
= 1950x^2
