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

Answer:
x=6
Step-by-step explanation:
150+35x=60x
-35x -35x
150= 25x
It is really simple. The ratio between both the triangles is 7, so you just divide 49 by 7(it gives you 7) to get the value of x. The answer is option (a) 7.

Good Luck!
To answer the item, we let x be the number of 2-point baskets and y be the 3-point basket, respectively. The system of linear equations that would allow us to express the given mathematically is,
x + y = 37
2x + 3y = 80
To determine the values of the variables, express x of the first equation in terms of y.
x = 37 - y
Substituting this to the second equation,
2(37 - y) + 3y = 80
The value of y from the equation is 6.
x = 37 - 6 = 31
<em>Answer: 31 two-point baskets</em>
