kow [346]

The precise equation that represents the situation is as follows:

  • $19, x ≤ 300
  • x > 300,
  • f(x) = 19 + 0.39(x - 300)

<h3>How to represent an equation?</h3>

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)

A survey of athletes at a high school is conducted, and the following facts are discovered: 33% of the athletes are football pla
sergejj [24]

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 :-

P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\=0.33+0.66-0.20=0.79

Hence, the probability that the athlete is either a football player or a basketball player = 0.79

Or we can write it as 79%.

What are some terms that you use in your everyday life that are really hard to define, yet they're incredibly important and freq
DiKsa [7]

Any expression, like "you're pulling my leg", or "there's more than one way to skin a cat." It's really hard to explain these things to people who haven't grown up with these expressions. Also, words like "the", "and", and others are super important in everyday life, but you really can't describe. Undefined terms are also important in geometry. A point is an undefined term, and so is a line. But without these two things, geometry would be impossible.

Hopefully this helps! Let me know if you have any more questions.
