Answer:
9
Step-by-step explanation:
f(x) = 2x+9
f(x) = 27
so, you get:
2x+9=27
2x=18
x=9
<u>Given</u>:
Let X and Y be two sets.
The two sets are given by 
and 
We need to determine the value of the set 
<u>Value of the set </u><u>:</u>
The value of the set is the set that contains all the elements that are at least in one of the two sets.
Hence, the union of the set is given by
Arranging in ascending order, we get;
Thus, the union of the sets X and Y is
No, we can only suppose that the observed distribution deviates from the expected distribution when we reject the null hypothesis.
<h3>What is a null hypothesis?</h3>
The null hypothesis exists as a specific mathematical theory that claims that there exists no statistical relationship and significance between two sets of observed data and estimated phenomena for each set of selected, single observable variables. The null hypothesis can be estimated to define whether or not there exists a relationship between two measured phenomena, which creates it useful. It can let the user comprehend if the outcomes exist as the product of random events or intentional manipulation of a phenomenon.
