Complete Question
Veronikas four test scores are 59, 80, 95, 88 and 93 if the outlier of 59 is removed what is the mean absolute deviation of the remaining four test scores?
Answer:
5
Step-by-step explanation:
We have the four test scores
80, 95, 88 and 93
Step 1
We find the mean of the 4 test scores
= 80 + 95 + 88 + 93/4
= 356 / 4
89
Step 2
The formula for Mean Absolute Deviation =
Summation( x - Mean)/n
Hence,
|(80 - 89 )+( 95 - 89) + (88 - 89) + (93 - 89)|/5
= 9 + 6 +1 + 4/4
= 20/4
= 5
Step-by-step explanation:
1. set it equal to 0 so t=5,9
2. this is wriiten in vertex notation so vertex is (7,4)
Obviously the Correct Step would give him the correct answer lol !
But, here he goes !!
✓ So, h = 5 ; k = 11 would make him correct
