An individual who has automobile insurance from a certain company is randomly selected. let y be the number of moving violations for which the individual was cited during the last 3 years. the pmf of y is the following. y 0 1 2 3p(y) 0.50 0.25 0.20 0.05(a) compute e(y).e(y) =(b) suppose an individual with y violations incurs a surcharge of $110y2. calculate the expected amount of the surcharge.$

Suppose that x and y are both differentiable functions of t and are related by the given equation. use implicit differentiation with respect to t to determine startfraction dy over dt endfraction in terms of x, y, and startfraction dx over dt endfraction .

Find the multiplicative inverse of 8-12i

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
