Answer:
There is a 13.61% probability that exactly 4 of the jobs were not completed within the bid time.
Step-by-step explanation:
For each job, there are only two possible outcomes. Either they are completed on time, or they are not. This means that 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.
Looking at a random sample of 8 jobs that it has contracted, calculate the probability that exactly 4 of the jobs were not completed within the bid time.
There are 8 jobs, so .
30% of them are finished on time, which means that 70% are not completed within the bid time. This means that
The problems asks for P(X = 4). So
There is a 13.61% probability that exactly 4 of the jobs were not completed within the bid time.
<u>Given:</u>
The given function is
We need to determine the reflection of f(x) over the x - axis
<u>Reflection over x - axis:</u>
The translation rule to reflect over the x - axis is given by
Thus, applying the rule, the function becomes
Multiplying both sides of the equation by -1, we have;
This can be written as
Hence, the reflection of the function over the x - axis is
Thus, Option A is the correct answer.
