SOLUTION: students in mr. einsteins science class complain about the length of his test. he argues that a test with more questionsis better for students because each question is worth fewer

Question 135284: students in mr. einsteins science class complain about the length of his test. he argues that a test with more questionsis better for students because each question is worth fewer points. all of mr. einsteins test are worth 100 points. each question is worth the same number of points.
a. make a table and graph that show how the number of points per question change as the number of questions increase. show point values for 2 to 20 questions in intervals of 2.....?
b. write an eqaution for the relationship between the number of questions n and the points per question p.
c. tell how the points per question changes as the number of questions increases from 2 to 4. from 4 to 6. from 6 to 8. from 8 to 10.
d. how do the answers for part (c) show that the relationship between the number of questions and the points per question is not linear

If x = 2; y = 50
If x = 4; y = 25
If x = 6; y = 50/3 = 16.666
If x = 8; y = 50/4 = 12.5
etc.
--------------------------
b. write an eqaution for the relationship between the number of questions n and the points per question p.
p = 100/n
------------------
c. tell how the points per question changes as the number of questions increases from 2 to 4. from 4 to 6. from 6 to 8. from 8 to 10.
See table in part "a"
--------------------------
d. how do the answers for part (c) show that the relationship between the number of questions and the points per question is not linear
As x changes in a constant way the points column changes in a multiplicative
way.
