HELPPPPPP The scatter plot shows a regression line of advertising dollars spent and sales. If the company were to spend $350,000
on advertising, what would be the predicted sales? A) $105 million B) $110 million C) $115 million D) $120 million
2 answers:
Answer:
<h2>D) $120 million</h2>Step-by-step explanation:
The scatter plot is attached. There you can match the value assigned to $350,000.
Using a red line, we find that the answer is between 115 and 125, closer 125 than 115.
So, if you look all choices, there are two possibilities, C and D. However, $115 million can't be the right answer because our graphic approximation is closer to 125.
Therefore, the right answer is D) $120 million.
If the company were to spend $350,000 on advertising, the predicted sales would be $120 million.

Let's go step by step:
a) You are given four couples of x and y values which model the relationship between the number of drinks and their cost. So, the couple means that if you buy zero drinks, you spend no money. That makes sense. The next information we have is
, which means that two drinks cost 3 dollars, and so on.
So, you simply need to draw on the grid the four points
b) The domain is the set of inputs. Since we only know the value of the function on four different points (we know the price for 0,2,4 and 6 drinks), the domain is discrete. In fact, a continuous domain must contain an interval (for example, is a continuous domain), whereas if you pick a certain number of points (like in this case: we picked 0,2,4 and 6), the domain is discrete.
c) Once the points are drawn on the grid, you can see that they all lie on the same line. To find that line, we will only need two of those points (once two points are fixed, there is only one line passing through them). In general, the equation of the line passing through and
is
Let's choose, for example, the first two points. The equation is
d) Now that we know the equation of the line, we can compute the cost of any number of drinks: the equation of the line is a function that associates a cost, y, with every possible number of drinks, x.
Of course, some associations will be odd - we can compute the cost of drink, but what would it mean?
Anyway, the question about the cost of two drinks seems more than reasonable, so let's see which y value is associate with the particular x value of 2:
So, two drinks cost 3 dollars.
