When you multiply a number by a percentage, you first convert the percent into a decimal.
You do this by moving the decimal point two places to the left and making the decimal point into % sign.
15% = 0.15
Then you multiply the decimal by the number you want to find the percentage of.
So, the answer to this question is <span>A. multiple the number by 0.15</span>

Let's look at each of the options;
Option A; This is correct because what occurred is that the concerned student by telling the adults adverse effect of plastics in our environment, he is indirectly influencing the adults to have a bad mindset about the plastics. He is leading them on by the way he phrased the word to ask the question.
Option B; This is not the reason why it is a response bias. The reason it is a response bias is because he led them on with his wording of the question.
Option C; Like said in Option A & B above, the scenario is that of a response bias since they are giving answers.
Option D; Voluntary response bias is a type of non-response bias and so it is not correct here
Answer:
Step-by-step explanation:
find the prime factors of given numbers:
126= 2*3*3*7- this side can be cut into any number here or combination of numbers as per factors
108= 2*2*3*3*3 - same as above
As per prime factors, the squares can be of sizes:
2×2, 3×3, 6×6, 9×9 and 18×18
The least number can be obtained with the biggest size option 18×18, this will give 7*6=42 square
Answer: 2.3
Step-by-step explanation:
0.9 inches to centimeters is 2.28600
Since the area of the rectangle is 30, we know the following:
(5)(x-2) = 30
Divide both sides by 5
x-2 = 6
Add both sides by 2
x = 8
That's your answer.
Have an awesome day! :)
