Different hotels in a certain area are randomly selected, and their ratings and prices were obtained online. Using technology, w

mash [69]

Answer:

Option C) The symbol y represents the predicted value of price.

Step-by-step explanation:

We are given the following in the question:

We find a regression equation with x representing the ratings and y representing price.

The equation has a slope of 130 and a y-intercept of 350.

Comparing with the slope intercept form:

$y = mx + c\\\text{where m is the slope and c is the y intercept}$

Thus, we can write the equation as:

$y = 130x + 350$

Here, y is the predicted variable that is the price, c is the price of hotel when a rating of 0 is given.

Thus, symbol y represents:

C) The symbol y represents the predicted value of price.

You start at (7, 2). You move up 5 units. Where do you end?

tankabanditka [31]

Answer:

(7,7)

Step-by-step explanation:

Because going up would be moving along the y-axis, then you would add 5 to the Y value which was 2 so therefore, if you move up 5 you'll be at (7,7).:)

The exponential function f(x) = 2^x undergoes two transformations to

Eddi Din [679]

Option A: It is vertically stretched

Option B: it is shifted down

Solution:

The exponential function $f(x)=2^{x}$ undergoes two transformations to $g(x)=5 \cdot 2^{x}-3$ .

<u>To determine how the graph changes:</u>

Consider the given exponential function $f(x)=2^{x}$ .

Let y = f(x)

Vertically compressed or stretched:

A vertically compression (stretched) of a graph is compressing the graph toward x-axis.

• if k > 1 , then the graph y = k• f(x) , the graph will be vertically stretched by multiplying each y coordinate by k.

• if 0 < k < 1 if 0 < k < 1 , the graph is f(x) vertically shrunk (or compressed) by multiplying each of its y-coordinates by k.

• if k should be negative, the vertical stretch or shrink is followed by a reflection across the x-axis.

Here, k = 5

So the graph will be vertically stretched.

Also, Adding 3 to the graph will move the graph 3 units down so, the graph is shifted down.

So, The graph is shifted down.

Hence option A and option B is the correct answer.

They are 13 sales people at a car dealership last year they each sold the same number of cars together they sold 1157 how many c

bonufazy [111]

Answer: each salesperson sold 89 cars last year.

Step-by-step explanation:

The total number of sales people at the dealership shop is 13.

Last year they each sold the same number of cars. The total number of cars that they sold together last year was 1157. Therefore, the number of cars that each salesperson sold would be

Total number of cars sold/ number of salespersons

It becomes

1157/13 = 89
