Answer:wow this is hard
Step-by-step explanation:
Find the volume of the cylinder and divide by 2:
V = pi * r^2 * h
V = 3.14 * 11^2 * 17
V = 6458.98
Divide by 2 since it's half full:
6458.98 / 2 = 3229.49
Now divide it by 46.2 to see how long it will take to drain out:
3229.49 / 46.2 = 69.902
So it will take approximately 70 seconds to drain out.
Distance formula: √((y2-y1)^2+(x2-x1)^2)
Plug in the values √((4-2)^2+(6-3)^2)
√((2)^2+(3)^2) = √(4+9) = √13 = 3.6
3.6 is your answer.
<u>Description</u><u> </u><u>of</u><u> </u><u>a</u><u> </u><u>Randomized</u><u> </u><u>block design</u><u> </u><u>for</u><u> </u><u>the</u><u> </u><u>experiment</u><u> </u><u>:</u>
Randomized block design involved the divison of subjects into units, called block. After which treatment are randomly applied to elements or subjects in each block.
Here, we make divide the 30 mature trees into 3 which means we have <em>3 blocks of 10 mature</em> trees each. The citrus <em>fertilizers A, B and C</em> are then applied randomly to each of the three units.
B.)
The randomized block design used in these experiments will correct for the possible error which could be introduced die to systematic error since each of the treatments(fertilizers A, B and C) would be used in each of the blocks.
