In stratified sampling, a sample is drawn from each strata (using a random sampling method like simple random sampling or systematic sampling). In cluster sampling, the sampling unit is the whole cluster; Instead of sampling individuals from within each group, a researcher will study whole clusters.
The graph of g(x) is shifted 4 units up ⇒ answer a
Step-by-step explanation:
Let us revise the translation
- If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)
- If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)
- If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k
- If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k
∵ The parent function f(x) = x
∵ g (x) = x + 4
- Substitute x in g(x) by f(x)
∴ g(x) = f(x) + 4
- g(x) is f(x) add by 4
- by using the rule of translation above
∵ g(x) = f(x) + k
∵ k = 4
∴ g(x) is the image of f(x) after translation 4 units up
∴ The graph of g(x) is 4 units above the graph of f(x)
The graph of g(x) is shifted 4 units up

Answer:
The average rate of change from x=0 to x=1 for f(x) is 0.
Step-by-step explanation:
We are given the function .
Now, the rate average rate of change of a function from to is given by .
As, we need the rate of change from x = 0 to x = 1.
So, we will find the values of f(0) and f(1).
i.e. i.e. f(0) = 3
and i.e. i.e. f(1) = 3
Thus, the rate of change from x=0 to x=1 is i.e. i.e. 0
Hence, the average rate of change from x=0 to x=1 for f(x) is 0.
Answer:
Option B
Step-by-step explanation:
<u><em>Complementary Angles add up to 90 degrees</em></u>
So,
Other Angle = 90-22
Other Angle = 68 degrees
Also Other Angle = 2x (Given)
So,
2x = 68
Dividing both sides by 2
=> x = 34
