Find the median of the given data. If the mean is 4.5...
5, 7, 7, 8,x,5,4,3 = x, 3, 4, 5, 5, 7, 7, 8
The median is 5. For the second part... The question is incomplete... “If the mean is 4.5...” Also, I have no idea if x should have been added or not. Even if it was, it doesn’t change the answer.
5% = 1/20
so if 35 pages are 1/20th of the book, the book would be 20 x 35 pages long.
20 x 35 = 700 Pages
The nearest whole number of 0.9 is 1
Let the number of units sold be n
Revenue = 65*n
Cost function = 5500 +4*n
Profit function = Revenue - Cost
=65n -(5500+4n)
61n-5500
