Answer: Anything that is 1202 or larger
In other words,
So we could have m = 1202, or m = 1203, or m = 1204, etc.
===============================================
Explanation:
- m = number of minutes used
- 0.07m = amount charged for those minutes used excluding the $25
- 0.07m+25 = total monthly bill now including the extra $25 fee
The monthly bill is at least $109.14, since this is the lowest amount she has been charged.
This says that the least number of minutes Martina has used is 1202 minutes.
So if m was a whole number, then m could be selected from the set {1202, 1203, 1204, ...}
Side note: 1202 minutes = 1202/60 = 20.033 hours approximately.
Answer:
11.44% probability that exactly 12 members of the sample received a pneumococcal vaccination.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they received a pneumococcal vaccination, or they did not. The probability of an adult receiving a pneumococcal vaccination is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
70% of U.S. adults aged 65 and over have ever received a pneumococcal vaccination.
This means that
20 adults
This means that
Determine the probability that exactly 12 members of the sample received a pneumococcal vaccination.
This is P(X = 12).
11.44% probability that exactly 12 members of the sample received a pneumococcal vaccination.
