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.
6^-3 / 6^5
Because the numerator has a negative exponent, use the negative exponent rule b^-n = 1/b^n
To do this move 6^-3 to the denominator:
1 / (6^5 * 6^3)
When you multiply identical numbers with exponents you add the exponents so (6^5 * 6^3) becomes 6^8
Now you have 1 / 6^8
Now raise 6 to the power of 8 to get:
1/1679616
Depending on the format your answer needs to be in you have 3 different answers:
1) 1/6^8 ( Leaving it as an exponent)
2) 1 / 1679616 (As a fraction)
3) 5.9537 x 10^-7 (As a decimal, round as needed)
