Answer:

Step-by-step explanation:

Given

Solving for (a): n

To find n;

We will utilize

Substituting values for XY and XZ

Dividing by -6

Solving for (b) XY

Substituting 3 for n

Solving for (c): XZ

Here’s the information: Drug User | Not a drug user | Totals Test positive | 475 | 475 | 950 Test negative | 25 | 9025 | 9050 Totals | 500 | 9500 | 10,000.

The student ought to fix the vehicle, as that would be more economical.

Let’s denote the distance of the first segment of the race as x and the second segment as 15 - x, then
x/8 + (15 - x)/20 = 1.125
5x + 2(15 - x) = 40 x 1.125
5x + 30 - 2x = 45
3x = 45 - 30 = 15
x = 15/3 = 5

Hence, the first segment of the race covers 5 miles, taking 5/8 = 0.625 hours or 37.5 minutes
The second segment then is 15 - 5 = 10 miles, with a duration of 1.125 - 0.625 = 0.5 hours or 30 minutes.

Answer:

The choices are not provided.

Nonetheless, we can depict the data with a plot.

To create a scatterplot, we will plot points, where the independent variable is represented by numbers 1 through 10, indicating each player’s position.

The points necessary for this plot are:

(1, 28)

(2, 13)

(3, 4)

(4, 8)

(5, 15)

(6, 10)

(7, 22)

(8, 7)

(9, 11)

(10, 15)

The accompanying image illustrates the plot corresponding to this dataset.
