The precise equation that represents the situation is as follows:
- $19, x ≤ 300
- x > 300,
- f(x) = 19 + 0.39(x - 300)
His cell phone plan provides 300 free minutes each month for a flat rate of $19.
let
x = number of minutes used
Therefore,
$19, x ≤ 300
For any minutes over 300, Andrew is charged 0.39 per minute.
Therefore,
if x > 300
f(x) = 19 + 0.39(x - 300)

Answer: 0.79 or 79%
Step-by-step explanation:
Given : The probability that the athletes are football players : P(A)=0.33
The probability that the athletes are basketball players: P(B)=0.66
The probability that the athletes play both football and basketball : P(A∩B)=0.20
Now, the probability that the athlete is either a football player or a basketball player is given by :-
Hence, the probability that the athlete is either a football player or a basketball player = 0.79
Or we can write it as 79%.
