Answer:
1512 cm³
Step-by-step explanation:
Formula
Volume of right rectangular prism = Length × Breadth × Height
As given
Two blocks of wood are shaped as right rectangular prisms.
The smaller block has a length of 9 cm, a width of 3 cm, and a height of 7 cm.
As given
The dimensions of the larger block are double the dimensions of the smaller block.
Length of the larger block = 2 × Length of the smaller block
= 2 × 9
= 18 cm
Breadth of the larger block = 2 × Breadth of the smaller block
= 2 × 3
= 6 cm
Height of the larger block = 2 × Height of the smaller block
= 2 × 7
= 14 cm
Put in the formula
Volume of larger wooden block = 18 × 6 × 14
= 1512 cm³
Therefore the volume of the wooden block is 1512 cm³ .

<em>Standard equation of a circle with a center at </em>
and radius 3 is:
![(x+4) ^{2} +(y+10)^{2} =9](https://tex.z-dn.net/?f=%28x%2B4%29%20%5E%7B2%7D%20%2B%28y%2B10%29%5E%7B2%7D%20%3D9)
Explanation:
<em>The equation of a circle with center at (h,k) and a radius of r is:</em>

Answer:
No. This convenience sample is very biased and is highly unlikely to be representative of national public opinion.
Step-by-step explanation:
The sampling as per its nature should be classed as convenience sample because of its definition: this method covers part of the population with easy to reach or close to hand.
This involves only those who will access the website and this can not be considered as representative of national public opinion.

<u>Let's see the answer options:</u>
<u />
No. This convenience sample is very biased and is highly unlikely to be representative of national public opinion.
Yes. This convenience sample is appropriate for the limited resources of a news website and is likely to be representative of the population.
- Incorrect as it is not representative of national public population.
Yes. This simple random sample is ideal and will be representative of the population.
- Incorrect as the method of sampling is not simple random
No. This systematic sample is very biased and is highly unlikely to be representative of national public opinion.
- Incorrect as the method of sampling is not systematic.
