Use a graphing calculator to evaluate the sum. Round to the nearest thousandth.
-$$\sum _ { \mathrm { k } = 5 } ^ { 10 } ( 0.53 ) \mathrm { k }$$
A) $0.085$
B) $0.043$
C) $0.087$
D) $0.045$

Quizplus · Accepted Answer

The sum can be calculated by evaluating the expression $0.53k$ for each integer value of $k$ from 5 to 10 and then adding those values together. The correct sum, rounded to the nearest thousandth, is $0.087$.

Use a Graphing Calculator to Evaluate the Sum ∑k=510(0.53)k\sum _ { \mathrm { k } = 5 } ^ { 10 } ( 0.53 ) \mathrm { k }k=5∑10​(0.53)k
