Select the best answer. a farmer is conducting an experiment to determine which variety of apple tree, fuji or gala, will produce more fruit in his orchard. the orchard is divided into 20 equally sized square plots. he has 10 trees of each variety and randomly assigns each tree to a separate plot in the orchard. what are the experimental unit(s) in this study?
(a) the trees
(b) the plots
(c) the apples
(d) the farmer
(e) the orchard

(b) The plots

Step-by-step explanation:

The plots are the experimental units as they are the objects subjected to the measurements. The variety of apple trees is the explanatory variable since they promote change in the experimental unit through two different treatments (Fuji or Gala variety). The farmer is the one conducting the experiment and the number of apples is the result to be analyzed. The orchard as a whole does not interfere in the experiment since each plot is being studied.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
