3.5.3 Test (CST): Functions
1 answer:
Based on the function shown in the image attached below, the range of this function is equal to {-8, -3, 5, 7}.
<h3>What is a range?</h3>A range can be defined as a set of all real numbers that connects with the elements of a domain. This ultimately implies that, a range is the solution set (output of a function) because it comprises all second elements (y-coordinates) of ordered pairs.
Based on the function (see attachment), we can logically deduce that the range of this function is given by {-8, -3, 5, 7} and they all mapped to the domain.

Answer:
C) Uniform distribution
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely. In this case, the probability of producing a defective light bulb from a production line is the same over an interval of 90 minutes, so the correct answer is C.
We can calculate the probability.
Uniform probability distribution
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X lower than x is given by the following formula.
For this problem, we have that:
Uniformily distributed over a 90 minute interval, that is, between 0 and 90, so and
.
We want to find
