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.

Isolate for x, y = mx + b
zavuch27 [327]

Answer:

x = (y - b)/m

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First subtract b from both sides:

y = mx + b

y (-b) = mx + b (-b)

y - b = mx

Next, divide m from both sides:

(y - b)/m = (mx)/m

x = (y - b)/m

x = (y - b)/m is your answer.

George wants to buy pets for each of his 5 grandchildren if he buys 3 pooples and 2 cats he will spend 1200 if he buys 2 poodles
Gre4nikov [31]

Answer:

Each poodle = $300

Each Cat = $150

Step-by-step explanation:

Let number of poodles be P and number of cats be C

"if he buys 3 pooples and 2 cats he will spend 1200" mathematically:

3P + 2C = 1200-------eq 1

"2 poodles and 3 cats he will spend 1050" mathematically:

2P + 3C = 1050 ------eq 2

So now we have a system of 2 equations with 2 unknowns, we'll solve by elimination

eq 1 x 3 : 3 (3P + 2C) = 3  (1200)

9P + 6C = 3600 ------ eq 3

eq 2 x 2: 2(2P + 3C) = 2(1050)

4P + 6C = 2100---------eq 4

By elimination : eq 3 - eq 4

(9P + 6C) - (4P + 6C) = 3600 - 2100

9P - 4P = 1500

5P = 1500

P = 300  (answer)

Substituting back into eq 1

3(300) + 2C = 1200

900 + 2C = 1200

2C = 1200 - 900

2C = 300

C = 150(answer)
