Answer:
d.a cluster sampling
Step-by-step explanation:
This plan exemplifies Cluster sampling. It is a sampling method where populations are placed into different separate groups like here into freshman, sophomore, junior, and senior classes. A random sample of these groups is then selected as here thirty students selected from each group to represent a specific population.<u> It is usually used in that type of research when there is no possible way to find information about a population as a whole.</u>
Answer:
D. 1000 gallons per hour
Step-by-step explanation:
5000 / 5 = 1000
Answer:
3200 = 168x + 8
Step-by-step explanation:
$3200 is the total sales in dollars, so we're going to plug that in for y (it says in the equation that y represents the total sales in dollars). And the rest of the equation stays the same.
I hope this helped!
Answer:
f(x) = x^2
g(x) = 4*x^2
=> For a value of x, the g(x) is 4 times larger than f(x).
=> g(x) is the stretched version of f(x) with stretched ratio = 4).
=> Option D is correct
Hope this helps!

1st thing you need to do is to graph the line y = x - 3 as a dashed line, since the it is just a less than symbol. Once the line is graphed, we need to decide which side to shade. I tend to use (0, 0) if at all possible. We check 0 < 0 - 3
Since 0 is not less than -3 then we shade away from the point (0, 0). That is how you find the answer.
