An automobile dealer conducted a test to determine whether the time needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used. because tune-up time varies among compact, intermediate, and full-sized cars, the three types of cars were used as blocks in the experiment. the data (time in minutes) obtained follow.
compact intermediate full size
analyzer computerized 50 55 63
electronic 42 44 46
the following regression model can be used to analyze the data for a randomized block design involving two treatments and three blocks.
e(y) = 0 + 1 x 1 + 2 x 2 + 3 x 3
a. show the values of the variables below. if your answer is "zero" enter "0".
b. i would say because of puberty
option b. 215.56 is the right answer.
path of the rocket can be modeled by the equation y = -0.04x²+8.6x+4.8
here y represents the vertical height of the rocket and x represents the horizontal distance in meters.
we have to calculate the horizontal distance covered by the rocket.
now we can say when rocket is landing y = 0 or vertical distance of the rocket will be zero.
then equation will be
-.04x²+8.6x+4.8 = 0
yes it would be 1/1 doubled is 2/2
