Answer:
What is the question?
You just gave a statement.
Step-by-step explanation:
The total number of people that will be selected is 14.
<u>Step-by-step explanation:</u>
For stratified random sampling at first we need to divide the population into some strata and then choose sample from each. For the given problem the response category is
Sample size of strata = (Size of entire sample by populaion size) multiply strata size
= (20 by 300) multiply 210
after solving we get, 14
therefore, 14 people will be selected.
One merit is that here since we divide the whole data into stratas and then select samples from that so it can be used as a guard against unwanted samples and also gives more accurate sample measure. Here since we required samples from the population who gave yes and no opinion so it is better to use stratified sampling method otherwise if we use simple random sampling then we may choose those samples who gave no opinion. But since we don't use that method so we can avoid this.
Answer:
3
Step-by-step explanation:
p-(9-(m+q))
5-(9-(4+3))
=5-(9-7)
=5-2
=3
Answer:
If the prism is trapezoid then you need to find the height and use this formula
1/2 x a+b x h
This has been done below you only need to fill in the height and do the shape for 3cm x 2cm as you haven't been clear in your question.
Volume = 8 x h x 10 = 80 x h cm^3
Hope this helps.
Step-by-step explanation:
Slope triangle prism and or rectangle
The area can be seen either by finding height of the triangle or working out the rectangle and halving the rectangle.
Step-by-step explanation:
Volume
6 x 8 = 48cm^2
48 x 5 = 230cm^2 for double (rectangle prism of 6 x8)
385/2 = 115cm^2 triangle slope prism
---------------
Area first
trapezoid front measures 6,5, 10
1/2 x 6 + 5 x h
=1/2 x 6 + 5 x h
= 8 x h x 10= 80 x h
Volume = 8 x h x 10 = 80 x h cm^3
