The <em>correct answer</em> is:
B) precise
Explanation:
Precision can be broken down into two pieces:
<em>Repeatability </em>- The variation observed when the same person measures the same thing repeatedly with the same device.
<em>Reproducibility</em>: The variation observed when different people measure the same thing using the same device.
If two measurements are very close to each other, this gives repeatability. If the measurements were made by different people, this gives reproducibility.
<em>Accuracy</em>, however, describes the difference between the measurement and the thing's actual value. This would not involve getting the same result repeatedly; it would be getting the <em>correct</em> value.
Answer:
40
![cm^{3}](https://tex.z-dn.net/?f=cm%5E%7B3%7D)
Step-by-step explanation:
The figure is a rectangular prism, so the formula would be Volume = length x width x height.
length = 6
cm
width = 2
cm
height = 2
cm
If you plug everything you have in the problem into the volume equation, you would get : Volume = 6
cm x 2
cm x 2
cm.
Without a calculator, I would first turn the mixed numbers into improper fractions.
- 6
= ![\frac{13}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B2%7D)
- 2
= ![\frac{5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D)
Volume =
x
x
When you multiply everything together you should get
.
As a mixed number, that would be 40

Answer:
Option A
Step-by-step explanation:
The complete question is shown in the attachment.
Note that: ![(f\cdot g)(x)=f(x)\cdot g(x)](https://tex.z-dn.net/?f=%28f%5Ccdot%20g%29%28x%29%3Df%28x%29%5Ccdot%20g%28x%29)
We need to multiply all the functions to see which of them satisfy the given criteria.
Option A
![x^2\cdot \frac{1}{x} =\frac{x^2}{x}=x](https://tex.z-dn.net/?f=x%5E2%5Ccdot%20%5Cfrac%7B1%7D%7Bx%7D%20%3D%5Cfrac%7Bx%5E2%7D%7Bx%7D%3Dx)
Option B
![\frac{2}{x} \cdot \frac{2}{c} =\frac{4}{cx}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7Bx%7D%20%5Ccdot%20%5Cfrac%7B2%7D%7Bc%7D%20%3D%5Cfrac%7B4%7D%7Bcx%7D)
Option C
![\frac{x-2}{3} \cdot 2-3x =\frac{-3x^2+8x-4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-2%7D%7B3%7D%20%5Ccdot%202-3x%20%3D%5Cfrac%7B-3x%5E2%2B8x-4%7D%7B3%7D)
Option D
![\frac{1}{2x-2} \cdot \frac{1}{2x+2} =\frac{1}{4(x^2-1)}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2x-2%7D%20%5Ccdot%20%5Cfrac%7B1%7D%7B2x%2B2%7D%20%3D%5Cfrac%7B1%7D%7B4%28x%5E2-1%29%7D)
The correct choice is A
