Answer:
78
Step-by-step explanation:
how to find the average?
add all the numbers up then dived by how many numbers their are
76+80+83+71+80+78=468
since their is 6 numbers you divide 468/6
the average is=78
The student's average score for these six tests is 78.
Given to us,
scores student received = {76, 80, 83, 71, 80, 78};
Number of test given by student = 6 test;
We know that for any given data, the average is the ratio of the sum of all data given to the number of data given. thus,
[tex]\rm \bold{Average\ Score=\dfrac{Sum\ of\ all\ the \ scores\ student\ received}{Number\ of\ test\ given} }[/tex],
[tex]\rm \bold{Average\ Score=\dfrac{76+80+83+71+80+78}{6} }[/tex]
[tex]\rm \bold{Average\ Score= \dfrac{468}{6} = 78 }[/tex],
Hence, the student's average score for these six tests is 78.
