Answer:
 x^2 - 6x + 9.
Step-by-step explanation:
f(x) = x^2 and g(x) = x - 3.
To find f(g(x))  we replace the x in f(x) by g(x).
f(g(x)) = (x - 3)^2
= x^2 - 6x + 9.

Answer:
<u>A) Matched pairs design</u>
<u>Step-by-step explanation:</u>
In<em> </em><em>experimental design</em>, the match pairs experimental design is one that often involves only two treatment conditions; which in this case are the 'refrigerated and the room temperature battery storage types'.
Thus, these two treatment conditions form a matched pair because we are told that 10 fully charged batteries are placed into each type of storage.
 
        
             
        
        
        
The variance for the data is  17,507. 5.
Given
The weekly salaries of a sample of employees at the local bank are given in the table below. 
Employee Weekly Salary Anja $245 Raz $300 Natalie $325 Mic $465 Paul $100.
<h3>Variance</h3>
Variance is the expected value of the squared variation of a random variable from its mean value, in probability and statistics.
The mean value of the salaries of employees is;

The variance is given by;

Hence, the variance for the data is  17,507. 5.
