Professor taught a few classes the following grade averages for the classes were, 82%, 86%, 91%, 74%, calculate the mean?

Convert all to decimal

82%=0.82

86%=0.86

91%=0.91

74%=0.74

Add them

3.33

Divide by 4

3.33/4= 0.8325 will be your mean

Hi Annag88,

Your Question:

Professor taught a few classes the following grade averages for the classes were, 82%, 86%, 91%, 74%, calculate the mean?

Definition:

Mean - "is the average of the numbers: a calculated "central" value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are."

Solution:

= 333 ÷ 4

= 83.25%

Final

Mean = 83.25%

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes. 

step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
