Antwan wants to know how often the residents in his neighborhood go to the beach. which sampling method will give valid results?

a.
he asks three random households from each street in his neighborhood.
b.
he asks all the members of the swim team at his school.
c.
he asks all his family members and friends.
d.
he posts a question on a community web site.

I think D would be the answer.

Step-by-step explanation:

The most people would see it on the website, making it, if you ask me, the most likely answer.

D

Step-by-step explanation:

A) he only ask the people most likely to go

B) only his family not his neighborhood

C) Voluntary so it wont be accurate as much

D) Makes the most sense with all of the above

hes is using Random sampling is a procedure for sampling from a population in which (a) the selection of a sample unit is based on chance and (b) every element of the population has a known, non-zero probability of being selected. his entire neighborhood to see how often the people there go to the pool

Systematic sampling: is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size.

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
