The slope would be 2 and the y-intercept would be 9
Step-by-step explanation:
Based off of the fitted line, we obtain expected values, given an input. If the input is 0 minutes remaining (meaning a student turns in a test with no time remaining), the expected value of their exam score is 87.
Proof -
So, in the first part we'll verify by taking n = 1.



Therefore, it is true for the first part.
In the second part we will assume that,

and we will prove that,








<u>Henceforth, by </u><u>using </u><u>the </u><u>principle </u><u>of </u><u> mathematical induction 1²+2² +3²+....+n² = n(n+1)(2n+1)/ 6 for all positive integers n</u>.

Answer: 5/4
Explanation:
We have the same denominator so we can just add the numerator.
= 6/8 + 4/8
=10/8
10/8 can be simplified
=5/4
