Answer:
(c) Multistage sampling
Step-by-step explanation:
Multistage sampling is a technique of sampling in which the population is divided in different stages or groups with the goal of reducing the sample size at each stage.
Here, multistage sampling is being used to obtain the sample of undergraduate students in the United States.
Hence, the correct option is (c), Multistage sampling.
Answer:
B ( 92 degrees)
Step-by-step explanation:
1. Find y
In order to find z, we need to find y.
All triangles add up to 180 degrees, so y would be
180 - (48 + 44) = 88
y is 88 degrees
2. Find z
So now we know y is 88, we can find z
The circle of all angles of y and z = 360 ( because full angle)
so our equation is:
(88 + z)2 = 360
Divide by 2
88 + z = 180
z = 92
Remark
This is like using the distributive principle only you are going backwards. Instead of trying to remove brackets, you are trying to create them.
Solution
Since you want to take - 6 outside the brackets you should divide both terms by - 6
<em><u>- 18a</u></em>: - 18a/- 6 = 3a which is left inside the brackets.
<em><u>-30:</u></em> - 30/-6 = 5
- 6(3a + 5)
Answer
-6(3a + 5)
14-3^2 x (-2)
=14-9 x (-2)
=14- (-18)
=32
