The regression equation which correctly models the data in this table is y = 1.49x - 107.5,
<h3>How to determine the regression equation?</h3>
From the table of data values, we have the following parameters:
∑x = 632
∑y = 404
∑x² = 80.142
∑xy = 51.448
Mathematically, the regression equation is represented by the following slope equation:
y = Bx + A
Next, we would determine A by using this expression:
A = (∑y·∑x² - ∑x·∑xy)/(n∑x² - (∑x)²)
A = (404×80,142 - 632×51,448)/(5×∑x² - (632)²)
A = (32,377,368 - 32,515136)/(5×80142 - 399,424)
A = -137,768/1286
A = 107.5
For B, we have:
B = (n∑xy· - ∑x·∑y)/(n∑x² - (∑x)²)
B = (5×51,448 - 632×404)/(5×∑x² - (632)²)
B = 1.49.
y = Bx + A
y = 1.49x - 107.5

Answer:
Step-by-step explanation:
The values of a, b, c, are:
- a is whatever is in front of term (including sign)
- b is whatever is in front of term (including sign)
- c is the constant term (including the sign)
So for , we clearly see that a is -3, b is 36, and since there is no constant term, c is 0
D. -3,-10,-17,-24,-31...this is an arithmetic sequence with a common difference of -7.
an arithmetic sequence...u have to be able to add the same number to each term to get the next term. On this sequence, the common difference is -7. This means by adding -7 to each term, we arrive at the next term.
