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.
Answer:
C. $19.65
Step-by-step explanation:
You have to find 20% of $98.25
This is equal to,
20% * $98.25 Because of usually means multiplication
= .20 * 98.25 Because .20 = 20%
= 19.65!
To solve for x you need to get it by itself
start by subtracting y
3/4x=e-y
then divide by 3/4 or multiply by 4/3
so, x=(4(e-y))/3
distribute
x=(4e-4y)/3 or x=4/3e-4/3y
