In a laboratory, under favorable conditions, a bacteria grows at an exponential rate. the number of cells c in the population is modeled by the function c(t)=ab^t, where a and b are constants and t is measured in hours. t                 c(t)             0                 8           1                 24 which function can be used to find the number of cells of bacteria in the population at time t? a. c(t)=8(1)^t b. c(t)=24(1)^t c. c(t)=8(3)^t d. c(t)=24(3)^t

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). =
