It is 46/7 you could multiply 6x7 and then add 4 = 46/7
-√121
10 1/11
10.13
10.2 repeating
Answer:
√(x2-x1)+(y2-y1)
√(4-1)+(6-7)
√(3)+(-1)
√2
I hope this is good enough:
First we find the sum of all values using the mean formula.
Then we subtract the value 70 from the total sum to get the sum of the values without 70 (in order to compute the mean of these values)
Then we compute the mean.
If you have any additional questions ask.
