Complete question is;
A student artist randomly selected two media from among: charcoal sketches, pencil drawings, and oil paintings, and then submitted all of her works in that media for a gallery showing. Identify the kind of sample that is described.
Answer:
Cluster sample
Step-by-step explanation:
Looking at the question, we can see that the media has already been grouped into 3 parts namely charcoal sketches, pencil drawings, and oil paintings. It has already been grouped into multiple groups for easy selection or identification.
Now this type of grouping is synonymous with cluster sampling because cluster sampling is a probability sampling technique in which the researchers divide the population into multiple groups known as clusters for research and this question clearly shows that the media has been grouped.
B is the answer pls mark brainliest
90,000 sq ft—any right-angled arrangement whose sides total 1200 will yield the same area.
Answer: B
Step-by-step explanation:
By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.
(2x+8)+(3x+5)=123 [combine like terms]
5x+13=123 [subtract both sides by 13]
5x=110 [divide both sides by 5]
x=22
Now, we know that the answer is B.
