Answer:
B
Step-by-step explanation:
A biased sample is a sample that does not accurately represent the population.
The survey asked only girls, but we can assume this school has both boys and girls. Therefore, by only asking girls, it creates a bias, because the boys in the school are not represented.
Therefore, the correct choice is B: biased sample.
The direct answer to your question is: "No".
because in that equation, 'x' is not 120 or130.
Let's find out what 'x' actually is:
<u>3/5 x = 52</u>
Multiply each side by 5 : 3x = 260
Divide each side by 3 : <em> x = 86 and 2/3 </em>
Answer:
The average of all textbooks is $38.60.
Step-by-step explanation:
Here's why to calculate average we do sum of all numbers divided by the number of numbers, for example if we average 2 and 3, we do 2+3 divided by 2. Which happens to be 2.5. Now for this problem we divide the sum by 3.
Therefore getting our answer of $38.60.
