The causal connection between the test grades of students and the amount of time and effort spent the students spend in studying and preparing for the test appears to be valid. This is valid because students who spend more time and effort studying would most likely be able to memorize more information of which they are most likely to come by in the test they take. Invariably, they'd be able to easily recall what they've memorize and give the right answers to the questions they are asked in the test, and this definitely will earn them higher test grades.
Answer:
Step-by-step explanation:
First view 2x-5y<15 as the equation 2x - 5y = 15. Find the x- and y-intercepts and plot them:
x-intercept: let y = 0 and find x: x = 15/2. Plot (0, 15/2).
y-intercept: Let x = 0 and find y: y = -3. Plot (0, -3).
