x = -5
Step-by-step explanation:
i took algebra a couple years ago :)
Option B is correct. <em>Point F</em><em> is the </em><em>only point </em><em>according to the option given</em>
A point is defined as an exact location with no size, length, or even width.
From the diagram shown, we have points, plane, and line segments.
- The only plane that we have is plane R making option C incorrect.
- A line is defined as a straight figure connected by two points. From the diagram, the line segments that we have are AN, BN, and AB falsifying options A and D.
The points are C, D, E, and F. Hence the correct option is B.<em> Point F</em><em> is the </em><em>only point </em><em>according to the option given</em>

Answer:
b. divide them into groups based on similarities
Step-by-step explanation:
Blocking is a method in statistics used to reduce the effect of nuisance variables in an experiment. Nuisance variables are those factors that could result in variations during the experiment. During blocking, subjects with similar features are grouped in the same block, and treatment is then administered to each of these subjects. In order to form blocks, blocking factors are used.
Blocking factors can affect the results of an experiment but they are of no importance to the experimenter. An example of a blocking factor is age. So, for Isamu who seeks to use blocking to deal with an extraneous factor in his experiment, blocking would enable him to divide his subjects into groups based on similarities.
Part 2 is 12.5 cm represents 5km
I worked this out by doing a ratio
5cm=2km
?cm=5km
you have to do 2 times 2.5 to get 5km so you do 5 times 2.5 to get 12.5cm
so the answer is that 12.5cm
Answer:
<em>C = 13π ≈ 40.82 units </em>
Step-by-step explanation:
C = 2 r π = d π
AB = 
= 13 units
<em>C = 13π ≈ 40.82 units</em> ( π ≈ 3.14 )
