Answer:
59
Step-by-step explanation:
As far as I know every triangle has to equal 180°
So if you add 98+23 you would get 121
subtract that from 180 and get 59
Hope this helps!
For part A add up all your students then add up all your students that like bike riding and skating (80+90) divide that by the total number of students who took the survey
For Part be put 20+40 over the toatl number of student then simplify
(new - original)/original = mark up
(78.08-64)/64= mark up
14.08/64 =mark up
.22 = mark up
multiply by 100 to get to a percent
mark up = 22 percent
<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.
