Answer:
Step-by-step explanation:
4 people use all three facilities, then
- 16 - 4 = 12 people use the gym and the track and do not use the pool;
- 9 - 4 = 5 people use the pool and the track and do not use the gym;
- 19 - 4 = 15 people use the gym and the pool and do not use the track.
At least two facilities use 4 + 12 + 5 + 15 = 36 people, 4 of them use all three facilities. Thus, the probability that a randomly selected person which uses at least two facilities, uses all the facilities is
Since all the options are in the slope intercept form, we find the equation using the formula,
We can find m, the slope using the formula,
On substitution,
We use any of the points, say (-2,-3) to determine the value of c.
The equation is therefore,
The correct answer is D.
