B because it’s a random sample and it’s not biased
Answer:
x^2 - xy + 1
Step-by-step explanation:
x^2 - xy + 2x/2x
2x/2x = 1
x^2 - xy + 1
This is the furthest we can simplify this expression with the given information.
I do not think we need to rewrite the first two numbers in the given above because they are already the simplest forms of themselves being whole numbers. However, the third number may be rewritten as 1/2 by dividing both numerator and denominator by 5 and the last one as 2/25 by dividing both numerator and denominator by 4.
When multiplying by multiples of 10, move the decimal place one place over to the right. 44,000 becomes 440,000.
