Answer:
(3, 0)
Step-by-step explanation:
Given the inequality y > -2x + 3 and y ≤ x - 2
The graph of the inequalities are plotted using the geogebra graphing online calculator.
The portion of the graph that is shaded with dark blue, represents the portion that supports the equation.
All the ordered pair points given in the question are also labelled in the graph.
From the graph we can see that only point (3, 0) falls in the area that supports the equation. Hence (3, 0) makes both inequalities true.
Answer:
There are 253 ways to select 5 participants
Step-by-step explanation:
Total number of volunteers to try a new brand of tennis shoes = 10
Number of volunteers to be selected = 5
We are supposed to find number of ways the research group select 5 participants.
We will use combination:
Formula:
Substitute n = 10 and r = 5
So,
Hence There are 253 ways to select 5 participants
