Answer:
a. It is flawed because it is a voluntary response sample
Step-by-step explanation:
Sampling method:
The process of selecting the samples from the population to conduct investigation is called sampling method. The sampling method must not be biased, meaning that the samples must be selected randomly.
In the given problem, 540 subjects were chosen for this survey. These subjects were internet users who responded to a question that was posted on a news website. This suggests that the subjects volunteered for the survey so that means their selection was not random at all, therefore, the sampling method is flawed because it is a voluntary response sample.
Note: A voluntary response sample is a sample where subjects decide themselves whether to be a participate in the survey or not.
Part A: the area of a rectangle is A= lw, so
A= lw
Height= 6x+3.= 9x
Width= 8
Which makes the expression to this area 9x x 8 ( 9x times 8 )
Part B: you do the same to get the expression here, so the expression would be
6x x 12 ( 6x times 12 )
The answer to this part is yes because both end up being 72x once you get the answer of each.
I dont get the question so im going to show you both solutions
if you’re asking for (2m+5)²=0 then
(2m+5)²=0 /√
2m+5=0
m=-5/2
if you’re asking only for (2m+5)² then
4m²+20m+25
Answer:
R u ok? Lol that must be intreasting
