Tim has to write two papers worth 50 points each. To pass, he has to get at least 45% of the total points. However, scoring less than 30% of the points on either paper, even if his total for both papers is above 45%, will result in him failing. Which graph represents the region in which Tim fails? (Assume that he scores x points on paper A and y points on paper B.)
2 answers:
Solution:
As, Given
Points scored in Paper A= x
Points scored in paper B= y
The Conditions in terms of equations which are applied , for passing of Tim is
Score should be above , 30% of 50= = 15 and 45% of 100=
1. x > 15
2. y > 15
3. x +y ≥ 45
The set of equations represent , if Tim fails
a. x< 15
b. y < 15
c. x +y ≤45
Option (C)
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions. Based on the above situation the graph that <span>represents the region in which Tim fails is the graph A. </span>
