Answer: Cluster Sampling
Step-by-step explanation: I just took this test and got it correct :)
Answer:
V = 120.6796
LA = 110.8513
SA = 174.8513
Step-by-step explanation:
Let me know if you need more of an explanation for any of these
First we need the height, one way to find that out is to use the diagonal of the and one of the diagonal edges of the pyramid. Specifically we will need half of the diagonal of the square. We will call the diagonal of the square d.

Gonna leave it like that for ease of writing. So then half of the diagonal is 
The height, h, will be
. Plugging everything in gets us 
last, we need to find slant height, which we will call s.

s is also the height of the triangles for purposes of finding area. Now for the volume and areas.
Volume is area of the base times height divided by 3, so 
Lateral area is the sum of the four areas of the triangles, and each of those are
so the whole lateral area is 4 times that. So we get 
Total surface area is the lateral surface area + the area of the base, so 110.8513 + 64 = 174.8513
Answer:
11 pounds of deluxe, 35 pounds of regular
Step-by-step explanation:
If d is pounds of deluxe coffee, r is pounds of regular coffee, and C is the total cost, then:
d ≥ 11
d + r ≥ 46
C = 7d + 5r
Since deluxe costs more than regular, we want to use as little as possible to minimize the cost.
d = 11
r = 35
C = 252
For this case we have the following function:
y = 9 (3) ^ x
Applying the following transformations we have:
Horizontal translations
Suppose that h> 0
To graph y = f (x-h), move the graph of h units to the right.
y = 9 (3) ^ (x-2)
Vertical translations
Suppose that k> 0
To graph y = f (x) -k, move the graph of k units down.
y = 9 (3) ^ (x-2) - 6
Answer:
2 units to the right
6 units down
