The linear equation in slope intercept form: y = mx + b.
We have:
This is not a linear equation.
Answer:
Cluster Sample
Step-by-step explanation:
Sometimes, a survey may involve people in a widespread geographical location. Taking samples from all part of the location may involve higher cost and even difficulty in accessing the whole area. Researchers therefore use a type of sampling method that help in overcoming this difficulty and still get results that can be used to judge the whole population.
This type of sampling is called cluster sampling. Cluster sampling involves sharing your population into clusters and randomly selecting two or more of the clusters. The researcher then samples from only the selected clusters.
In the question above, the population is already shared into clusters, in the form of neighbourhoods. The municipality then randomly selected 31 neighbourhoods out of the whole neighbourhoods in the city, just like in cluster sampling, then samples from only the selected neighbourhood. This is why the selected samples are cluster samples.
<u>Given</u> -
- the diameter of a semicircle is 6 yards.
ie. d = 6yd
ps - use 3.14 for a
<u>To find</u> -
- the semicircle's perimeter
<u>Solution</u> -
As we know the formula to find the perimeter of the semicircle is 2r + πr.
But A.T.Q we are only provided with the diameter. As we know that the radius is half of the diameter. ie, r = d/2.
Hence, d = 6
r = 6/2
r = 3 yd
Perimeter of semicircle = 2r + πr
Perimeter of semicircle = 2(3) + 3.14(3)
Perimeter of semicircle = 15.42 yd
<u>Hence forth the semicircle's perimeter is 15.42 yd</u>
Answer:
Step-by-step explanation:
First figure out how much he makes an hour. So, take $24.75 ÷ 3(hours)= $8.25
Now, take $8.25 x 20(hours)= $165.00
