The regression equation is 
, and it will take 31 weeks to have $50.00
<u>(a) The linear regression equation</u>
To do this, we make use of a graphing calculator;
From the graphing calculator, we have the following calculation summary:
- The sum of X = 45
- The sum of Y = 83
- Mean X = 4.5
- Mean Y = 8.3
- Sum of squares (SSX) = 82.5
- Sum of products (SP) = 128.5
The regression equation is then represented as:
Where:
and 
So, we have:
Approximate
Approximate
This means that, the regression equation is
<u>(b) Predict the time to have $50.00</u>
This means that:
So, we have:
Subtract 1.29 from both sides
Divide both sides by 1.56
Rewrite as:
Approximate
Hence, it will take 31 weeks to have $50.00

Part A.
The area of a triangle is given by the product of its base and the height relative to that base.
Since these triangles have the same base b and same height h, they have the same area.
Part B.
The area of a rectangle or parallelogram is given by the product of base and height. Since these figures have the same base and height, they have the same area.
Part C.
These figures have different shapes, so we can't affirm that they have the same area.
Part D.
The height shown in the image is not the height relative to side b, therefore we can't affirm that the triangles have the same area.
<span>y(1) = 0
y'(1) = e
y" = c1ex + c2e-x
y' = c1ex - c2e-x
for solving c1, 0 = c1e1 + c2e-1
this implies that c1 = - (c2/e2) and
to solve c2
e1 = (-c2e-2)e1 - c2e-1
e1 = (-2c2e-1)
c2= - (e1/2e-1) = - (e2/2)
c1 = - (c2/e2) = (e2/2e2)
Therefore y =(e2/2e2)ex - (e2/2)e-x</span>
-3, -1, 1, 3, 5 would be five of them.
