the coefficient of variation of two series are 24% and 40% and their standard deviation are 6 and 8 find the respective means​

explanation:

step-by-step explanation:

y - 25 = 2 ( x - 10 ) should be the answer

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
