During Samuel’s experiment, the experimental probability was 0.25. What else must be true about the experiment?
antiseptic1488 [7]

Answer:

The experimental probability of the outcome is 1/4

Step-by-step explanation:

If Samuel's experiment probability was 0.25, this depicts that the experimental probability of the outcome is 1/4, because:

1/4=0.25

Two points on the line are (0, 4) and (7, 18). Use the points to first determine the slope and y-intercept. Then write the equat
Nadya [2.5K]

9514 1404 393

Answer:

  a.  m = 2; y intercept = (0, 4); y = 2 x + 4

Step-by-step explanation:

The slope can be found using the formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (18 -4)/(7 -0) = 14/7

  m = 2

The y-intercept is the first given point: (0, 4).

The equation for the line in slope-intercept form is

  y = mx + b

Here, we have m=2 and b=4, so the equation is ...

  y = 2x +4
