So 1 would be 5r+20 and then the second one would be
To obtain an estimate of a parameter of a population, we use confidence intervals.
Confidence intervals:
The larger the sample size, the closest the parameter estimate is to the value of the population, as the margin of error of confidence intervals is inversely proportional to the sample size, that is, a greater sample leads to a smaller margin of error.
Thus, you should select the highest sample size in the options.

Answer:
3 and i use flvs too, also that pfp is fire
Step-by-step explanation:
Answer: (30m-9n)/270
First we start with m/9-n/30.
We multiply the denominators to get 270.
Then we multiply the numerators by the original denominators to get (30m-9n).
To check, we can use m=2, and n=4
2/9-4/30=4/45
(30*2-9*4)/270=24/270=4/45
First,let's find the slope-intercept form of equation which is y=mx+b, where y and x are coordinates, m is the slope and ,c is the y-intercept
y+6.75=0.25(x-1) y=0.25(2)-6.5
y+6.75-6.75=0.25x -0.25 -6.75 y=-6
y=0.25x-6.5
(2,-6) is the only correct answer I think is on the line with this equation.
