Answer:
The mid-point of AB is (5,6)
Step-by-step explanation:
The mid-point of two points lies between the middle of two points or divides the line in two equal parts.
The formula for finding mid-point, M, is:

Here (x1,y1) are the coordinates of first point and (x2,y2) are coordinates of second point.
Given
(2, 3) and (8,9)
Putting the values in the formula

Hence,
The mid-point of AB is (5,6)
5(3x-7)=20
15x-35=20
15x= 55
x= 55/15
x= 11/3
Plug this x value in.
6(11/3)-8
66/3 -8
22-8
14
Final answer: 14
Answer:
a. A two-sample z-test for a difference in sample proportions
Step-by-step explanation:
We are told that there are two supermarkets in the research named X and Y.
That a random number of shoppers were selected in each supermarket.
Thus means we have two different sample proportion.. Since a different number of people were randomly selected from each supermarket and a different number of people purchased the product.
Thus, we will have 2 sample proportions one for supermarket X and the other for supermarket Y.
In addition, the position of the product was different in both supermarkets.
Thus, we can say that this is a 2 sample Z-test for difference in their sample proportion.
