Answer:
Sample: few thousand adults
Population: all the adults
Step-by-step explanation:
A sample is a subset of the population, selected randomly.
In this case:
The sample consist of the few thousand adults selected to determine the opinions about the National polls.
The population consist of all the adults belonging to the said nation.
Consider an example about the new President election.
To determine which of the two candidates (say <em>A</em> and <em>B</em>) has a higher probability of winning the President election, the election society took a random sample of voters and asked who they think will be a better president.
The sample selected will be large enough, probably 10% of the population of all voters.
From this study it can be estimated which candidate has the higher chance of winning.
Since x=8y, subsitute 8y for x in other equation
y=6x-11
y=6(8y)-11
y=48y-11
minus y both sides
0=47y-11
add 11 to both sides
11=47y
divide both sides by 47

subsitute taht for y to find x
x=8y




in (x,y) form
(x,y)
C. So he can find a job that doesn’t include writing



add 15 to both sides:


subtract 6x from both sides:


Both sides are equal : true for all x
