A 25 gram sample of a substance that's used for drug research has a k-value of 0. 1208. N = Noe No = initial mass (at time t = 0) = mass at time t k - a positive constant that depends on the substance itself and on the units used to measure time t = time, in days. Fine the substances half life, in days, round your answer to the nearest tenth​

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). =
