Suppose that you have a large data set whose mean is 4.5 and variance of 2.1. define a linear transformation which will result in a data set whose mean and variance is 100.
mean of 4.5 and variance of 2.1. linear transformation will result in a data set whose mean and variance is 100

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

answer: 72: 111

step-by-step explanation:

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)
