Answer:
-21
Step-by-step explanation:
It would have to be -21 because there's -7, but the threes not negative so it would have to be -21
13 quarters = 3.25 and 3 dimes =.30 which = 3.55
If you meant:
64.3-3*(2³)/2
That would be 52.3 :)
Answer: a) Mean = 5, Median = 5
b) Mean = 15, Median = 5
c) Due to presence of outlier i.e. 99.
Step-by-step explanation:
Since we have given that
1,2,3,4,5,6,7,8,9
Here, n = 9 which is odd
So, Mean would be

Median = 
If 9 is replaced by 99,
1,2,3,4,5,6,7,8,99
So, mean would be

Median would be same as before i.e. 5
The mean is neither central nor typical for the data due to outlier i.e. 99
Hence, a) Mean = 5, Median = 5
b) Mean = 15, Median = 5
c) Due to presence of outlier i.e. 99.
