The decimal form of 80% is . 80 meaning you have 80 parts of 100 so the fraction would be expressed as 80/100. Then this fraction can be further reduced, first I would devide both the numerator and denominator by ten so you are left with 8/10 which can be further reduced.
The answer is 180mm^2. (B)
First, we can decompose the shape into a rectangle and a parallelogram. Let’s start with the rectangle.
Formula for a rectangle: bh
The base is 6 while the height is 12. You multiply like so. 6*12=72.
The area of the rectangle is 72.
The formula of a parallelogram is the same as the rectangle. (Bh)
To identify the base in this parallelogram, you would subtract the whole base length, 15 by half of the base length, 6.
15 - 6 = 9.
So the other half base length is 9.
You can simply transform a parallelogram into a rectangle by decomposing the parallelogram into two right triangles and a rectangle. You would take the right triangle at the bottom of the figure and move it to the top of the parallelogram in the photo. Thus, becoming a rectangle.
Now, we can identify the base and the height. The base of the parallelogram is 9 while the height is 12.
You would then multiply 9 by 12 like so to get 108.
After finding the area of the rectangle and parallelogram, you would add them up.
72 + 108 = 180mm^2
Therefore, making the answer choice B.
Answer:
-125 × 125 equal to -15,625
Answer / Step-by-step explanation:
To properly understand the principle behind the solving of this question, it would be necessary to define and go through some basic terms and their definition.
Therefore to start with, a completely randomized single factor is a type of experiment in which One factor of two or more levels has been manipulated. e.g, the experiment may be investigating the effect of different levels of cost, expenditure or different advertisements
Also, it should be noted that in the area of groping of the experiment, At this point, Each group of different level receives one of the a levels of the independent variable with participants being treated identically in every other respect. The two-group experiment considered previously is a special case of this type of design.
Consequentially, the answer to the narrative of the question would then be:
N= 3 factors levels x 5 replicates = 15
Degrees of freedom for the factor: a – 1 = 3 – 1 = 2
Degrees of freedom Total = 15 – 1= 14
Degrees of freedom error = Total – factor = 14 – 2 = 12
Bounds of P-value for F = 2.91 with 2 and 12 degrees of freedom are
= 0.01 < P < 0.05
