In a factory average male worker is rupees 150 and their standard deviation is 15. In the same factory average female worker is rupees 140 and their standard deviation is 12. Find the coefficient of variation of both the worker and hence say whose wage is more consistent.​

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
