Question

in your chemistry class, your final grade is based on four categories. the categories are tests, labs, assignments, and a final exam. suppose you earned the following grades in each of the categories; 60% on tests, 64% on labs, 45% on assignments, and 40% on the final exam. if tests are worth 29%, labs are worth 15%, assignments are worth 10%, and the final exam is worth 46%, determine your final grade in the course. record the grade below as a percentage accurate to two decimal places.

Explanation:

Step1: Calculate weighted - grade for tests

$60\%\times29\% = 0.6\times0.29=0.174$

Step2: Calculate weighted - grade for labs

$64\%\times15\%=0.64\times0.15 = 0.096$

Step3: Calculate weighted - grade for assignments

$45\%\times10\%=0.45\times0.1 = 0.045$

Step4: Calculate weighted - grade for final exam

$40\%\times46\%=0.4\times0.46 = 0.184$

Step5: Calculate final grade

$0.174 + 0.096+0.045 + 0.184=0.5$

Answer:

$50.00\%$
