What is the best way of choosing a sample to statistically represent a population? Why? What is a biased sample? How can biased sampling affect the statistical study of a
population?
Search the Internet and give two or more real-world examples of biased sampling
leading to unexpected or unfavorable outcomes. In each case, how could the sample
have been improved to make a more accurate inference about the population?

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

$79500

step-by-step explanation:

126 maybe. sorry

the answer is d.x= 90°

y= 50°

arc lm= 100°

i got this one chief
