Question 644841: My last one I need help with please
Starting with the data values 70 and 100, add three data values to the sample so that the mean is 85, the median is 76, and the mode is 76. Please show all of your work.

I have this ...
Since the mode is 76, at least 2 of the values must be 76.
Mean = (1/9)(70 + 76 + 76 + x + 100) = 85

Hi,

Mean = (1/9)(70 + 76 + 76 + x + 100) = 85

Mean = highlight%281%2F5%29%2870+%2B+76+%2B+76+%2B+x+%2B+100%29+=+85

 solve for x
