Answer: 4 hours 30 minutes
Step-by-step explanation: 36/8 = 4.5 hours
hours = 4, minutes = 0.5*60 = 30
This is a incomplete problem...
Answer:
8
Step-by-step explanation:
Given that in a sample of n = 6 scores, the smallest score is X = 3, the largest score is X = 10
Mean = 6
Since mean = 6 we get sum of all the 6 scores = 
Now II part says 10 is changed to 20
i.e. original sum = 36
Changed value = 10
Adjusted value =26
Add: new value =22
New sum =48
So we have sum = 48
New mean= 
(This can also be done using the formula
old mean + positive change in one score/6)
Just saying, this angle is a 45 degree angle.
and the X on both is '-1'
I think?
hope this helps. im not good at math..- :)
