On a quiz worth 5 points, four students earned a 5, seven students earned a 4, six students earned a 3, two students earned a 2, and one student earned a zero. Find the average score. (round to the tenths place)

The average score is 3.5.

Step-by-step explanation:

The average of a data set is the middle value or the most typical value of the set. It computed by dividing the sum of observations by the number of observations.

The sample space of the scores are:

S = {5, 5, 5, 5, 4, 4, 4, 4, 4, 4, 4, 3, 3, 3, 3, 3, 3, 2, 2, 0}

Total number of students = 4 +7 + 6 + 2 + 1 = 20.

The average score is:

Thus, the average score is 3.5.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
