Answer:
a simple random sampling.
Population is all the customers of the electronics chain store.
Step-by-step explanation:
Given that the marketing manager for an electronics chain store wants information about the ages of its customers. Over the next two weeks, at each store location, 100 randomly selected customers are given questionnaires to fill out asking for information about age, as well as about other variables of interest.
Here since these 100 customers are selected at random no groups or partitions were made.
So this cannot be stratified or cluster. Systematic sampling is done with a pre plan and here it is not mentioned. Convenience sampling is to save time the first customers or at a particular place selected. Here it is not
So this is nothing but a simple random sampling.
Population is all the customers of the electronics chain store.
For this case, we have that by definition, be given two functions f (x) and g (x). So:
![(f-g) (x) = f (x) -g (x)](https://tex.z-dn.net/?f=%28f-g%29%20%28x%29%20%3D%20f%20%28x%29%20-g%20%28x%29)
We have:![f (x) = - 3x-5\\g (x) = 4x-2](https://tex.z-dn.net/?f=f%20%28x%29%20%3D%20-%203x-5%5C%5Cg%20%28x%29%20%3D%204x-2)
So:
(f-g) (x) = - 3x-5- (4x-2)
We have to:
![- * + = -\\(f-g) (x) = - 3x-5-4x + 2](https://tex.z-dn.net/?f=-%20%2A%20%2B%20%3D%20-%5C%5C%28f-g%29%20%28x%29%20%3D%20-%203x-5-4x%20%2B%202)
Equal signs are added and the same sign is placed while different signs are subtracted and the sign of the greater is placed
![(f-g) (x) = - 7x-3](https://tex.z-dn.net/?f=%28f-g%29%20%28x%29%20%3D%20-%207x-3)
Answer:
Option D
Very interesting wording but from what I gathered, scaling down by a factor of 1/10 would be 64- 6.4(1/10 of 64) so your final answer would be 57.6
Hope this explanation helps ;)
