The expression which represents the function required to be generated; (f +g)(x) as in the task content is; 13x -2.
<h3>What is the expression which represents the function required?</h3>
It follows from the function definitions in the task content that the functions given are;
f(x) = 4x +5
g(x) = 9x -7
Hence, the value of (f +g)(x) = f(x) + g(x) and ultimately;
= 4x +5 + 9x -7
= 13x -2

2+3+1 = 7
£72 / 7 = £10.28
Answer:

Answer:
The store can be 90% confident that the interval from 0.293 to 0.355 captures the proportion of all customers of this store who have moved in the past 5 years.
Step-by-step explanation:
The confidence interval provides a range of values (lower and upper bound) based on a certain confidence level at which the true proportion or mean value of a given sample mean or proportion exists. In the scenario above, the confidence level is 90% and the confidence interval is 0.293 to 0.355. Hence, we can be 90% confident that the true proportion of all customers of the store who have moved within the last five years exists within this interval.
