Step-by-step explanation:
Wane was asked to solve the inequality
He decides that he needs to multiply both sides by 3.
We need to tell if the step is correct?
So, solving the inequality
We need to multiply both sides by 3, to get value of x i.e.
So, Wanes step is correct.
The correct option is Option A: Yes, that is the correct step
Answer:
There is a 25.52% probability of observating 4 our fewer succesful recommendations.
Step-by-step explanation:
For each recommendation, there are only two possible outcomes. Either it was a success, or it was a failure. So we use the binomial probability distribution to solve this problem.
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.
In this problem we have that:
If the claim is correct and the performance of recommendations is independent, what is the probability that you would have observed 4 or fewer successful:
This is
In which
There is a 25.52% probability of observating 4 our fewer succesful recommendations.
