Answer:
16 minutes
Step-by-step explanation:
Because the tank already holds 5 gallons of water, you only need to find the number of minutes to fill 4 gallons of water.
Because it fills at a rate of 1/4 gallons a minute, it takes 4 minutes per gallon of water.
Since we are dealing with 4 gallons of water to be filled, we multiply 4 · 4 to get the number of minutes.
4 · 4 = 16
16 minutes
Part C: Treat these two expressions as separate functions. Then f(x) = 4^(-x) and g(x) = 2^x + 3. Graph these functions separately on the same set of coordinate axes. Determine the coordinates of the point of intersection of the two graphs. That's your "solution," or at least the x-component of it. To find the y-component, substitute your "solution" into either f(x) or g(x). Write your final solution in the form (x,y).

Step-by-step explanation:
A binomial probability density function should be used to represent the probability
<h3>How to determine the type of
probability density?</h3>
The given parameters are:
- Proportion that plays sport, p = 32%
- Number of students selected, p = 50
- The probability, P = (x ≤ 15)
The proportion that plays sport indicates that
68% of the students do not play sport
So, we have two events, which are
- Play sport
- Do not play sport
When there are two possible events, then the binomial probability density function should be used
