Check the picture below.
running a perpendicular line like so from the right-angle, makes three similar triangles, the large, containing the smaller ones, and a medium and a small one. Now, using proportions, you can just use there, the medium and smalle to get "x".
Answer:
C.) each treatment is thought of as a value of the explanatory variable
Step-by-step explanation:
The main purpose for using randomization in an experiment is to control the lurking variable and establish a cause and effect relationship.
If we do not control lurking, or confounding, variables, we cannot accurately establish a cause and effect relationship; this means we cannot ensure that each treatment is a value of the explanatory variable.
Answer:
20 square units
Step-by-step explanation:
You count how many across the parallelogram is (which is 4) and you count how high it is (which is 5). Then you multiply 5×4* which equals 20 square units.
*The reason you do this is because base×hieght=area
Answer:
4
Step-by-step explanation:
if you had 2 monkeys and another 2 monkeys and you put them in a pen together then you will have 4 monkeys in the pen
hope this helps :))
If ABC and DEF are complementary, then the value of x will be,
90 - ABC = x
90 - 53 = x
x = 37°
