165/300 -> 55%
This doesn't make much sense though, either the question is out of context or there is some typo because empirical probability is based on results you get from an experiment and actually doing the trial, not on what happens mathematically

Which of the following is correct equation for the trend line in the scatter plot? A. Y= 2/5 x -2 B. Y= 5x-1 C. Y= 5x +5 D. Y= -
Dafna11 [192]

Answer: C. Y = 5x + 5

Step-by-step explanation:

    We need to write, or decide on, the equation for the blue line as this line represents the trend line for this scatter plot. We will write this in slope-intercept form. <em>See attached for a visual</em>.

    First, we will find our slope. We will use \frac{rise}{run} for this since we have a graph with clear points. See attached, we count up [5] and then count to the right [1] for a slope of 5.

     -> Slope = 5

   Now, we will find our y-intercept. This is where the line intersects the y-axis. The line hits the y-axis at point (0, 5) giving us a y-intercept of 5.

     -> Y-intercept = 5

   Lastly, we will write our equation and decide on an answer.

y = <em>m</em>x + <em>b</em>

y = (5)x + (5)

Y = 5x + 5

             C. Y = 5x + 5

Solve for x and y y+8=-4(x+7)
Sedaia [141]
Because you can't solve for two variables at once, you can guess and trial/error.
You can also give x or y any value, and then solve for the opposite variable.

x = 0
y = -36
for example. There are more solutions.

   y + 8 = -4(x+7)
-36 + 8 = -4(0+7)
      -28 = 0 - 28
      -28 = -28
