Answer: See explanation
Step-by-step explanation:
Cluster sampling, is a form of sampling whereby the population is divided by the researchers into smaller groups that are referred to as clusters and then the sample will be taken from the clusters formed.
Convenience sampling is when a sample is drawn based on the available population.
Systematic sampling is when a sample is gotten when the members are taken at regular intervals e.g 5th person, 12th items etc.
Simple random sampling is when the sample is selected from the larger population and in this case, every member involved can be selected as they all have an equal chance.
Based in the definition above, the answers will be:
a. Cluster sample
b. Convenience sample
c. Systematic sample
d. Simple random sample
50 POINTS PLEASE HELP! Write g (x)=2f (x) as a piecewise function f (x) is defined as follows:
SEE PICTURE
Step-by-step explanation:
Since g(x) = 2f(x), we apply scalling parallel to the y-axis by a factor of 2 onto f(x).
For x + 6 if x < 2,
It becomes 2(x + 6) if x < 2.
We have 2x + 12 if x < 2.
For x² + 4x - 15 if 2 <= x <= 5,
It becomes 2(x² + 4x - 15) if 2 <= x <= 5.
We have 2x² + 8x - 30 if 2 <= x <= 5.
For 5 - x if 5 < x,
It becomes 2(5 - x) if 5 < x.
We have 10 - 2x is 5 < x.
The answer is the 1st option.

For parallelogram ABCD, find m<1
Answer:
b
Step-by-step explanation:
the answer is
the angel m<1= 36°
The measure of angle m<1= 36°.
What is a parallelogram?That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
WE are given that angle CAD = 36 degree
So, we know that parallelogram has parallel opposite sides.
Thus according to alternate interior angle we can say that;
angle CAD = angle m<1 = 36
therefore, the measure of angle m<1= 36°

Find c. Round to the nearest tenth. Laws of sines
9514 1404 393
Answer:
c ≈ 56.3 cm
Step-by-step explanation:
I find it convenient to turn the given equations upside down. Then you just need to multiply by sin(C) to get the solution.
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B) = (27 cm)sin(102°)/sin(28°)
c ≈ (27 cm)(0.978/0.469)
c ≈ 56.3 cm

x/5 + 20 = 20.1
5x + 20 = 20.1
Answer:
No solution
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
a) The value of x in equation (a) is x = 0.5.
b) The value of x in equation (b) is x = 0.02.
Let's solve the equations for the value of x:
a. X/5 + 20 = 20.1
Step 1: Subtract 20 from both sides to isolate the term with x:
X/5 = 20.1 - 20
Step 2: Simplify the right side:
X/5 = 0.1
Step 3: To solve for x, multiply both sides by 5:
X = 0.1 * 5
X = 0.5
So, the value of x in equation (a) is x = 0.5.
b. 5x + 20 = 20.1
Step 1: Subtract 20 from both sides to isolate the term with x:
5x = 20.1 - 20
Step 2: Simplify the right side:
5x = 0.1
Step 3: To solve for x, divide both sides by 5:
x = 0.1 / 5
x = 0.02
So, the value of x in equation (b) is x = 0.02.

What is the volume of a rectangular prisim with the following dimensions?

= 120
if my answer helps please mark as brainliest.
Answer:
120³
Step-by-step explanation:
Hi!
This is very easy you just need to know the formula for finding the area of a rectangular prism. I attached something to help you with that but I also have an explanation.
The formula to find the area of a rectangular prism is L x W x H,
or in full words Length x Width x Height.
So now lets see what the problem has given us so we can plug things in.
Length = 4
Width = 3
Height = 10
Wow, it gives us all of it!
So now we just have to plug these numbers into the equation and solve.
So :
Length x Width x Height
4 x 3 x 10
Now we solve it :
4 x 3 = 12
And then we take 12 and multiply it by the last 10 in the equation.
12 x 10 = 120
And that is your answer, the volume of the rectangular prism!
Make sure to add a ³ after the 120 like so :
120³
This tiny 3 represents volume in math since the shape is 3D.
And if there are units of measurement involved like feet or inches make sure to put that in there as well like so :
120 feet³
I hope this helps!

What is a parallelogram?
A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
The proof is as follows;
STATEMENTS REASONS
1) AM = CM and BM = DM Given
2) m ∠ AMB = m ∠ DMC and
m ∠ AMD = m ∠ BMC Definition of Vertical angles
