Clayton and timothy took different sections of introduction to economics. each section had a different final exam. timothy scored 83 out of 100 and had a percentile rank in his class of 72. clayton scored 85 out of 100 but his percentile rank in his class was 70. who performed better with respect to the rest of the students in the class, clayton or timothy? explain your answer. clayton, since his score is higher. clayton, since his percentile score is lower. timothy, since his score is lower. timothy, since his percentile score is higher.

Fourth option is correct.

Step-by-step explanation:

Since we have given that

Timothy scored 83 out of 100.

His percentile rank in his class = 72

Clayton scored 85 out of 100.

His percentile rank in his class = 70.

Since Clayton's percentile rank is lower than Timothy's rank.

So, Timothy performed better with respect to the rest of the students in the class.

Hence, Timothy as his percentile score is higher.

Therefore, Fourth option is correct.

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

570, the answer is 570, hope it
