The constant term in the given equation is -3. This is the point where the graph must cross the y-axis. Graph B crosses at +3, so is not the answer.
The coefficient of x is 3/4. This means the line rises 3 units in 4 horizontal units. The line in Graph C appears to rise 3 units in 2 horizontal units, so is not the answer.
Graph A has the correct y-intercept and slope, so is the correct choice.
Answer:
Question 1:
(b) 4,445
Question 2:
(c) 2.1%
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error is of:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
Question 1:
We have no previous estimate for the population proportion, so we use
.
The sample size is n for which M = 0.015. So






Samples above this value should be used, and the smaller sample above this value is of 4445, so the answer is given by option b.
Question 2:
Now we find M for which
.



So 2.1%, and the correct answer is given by option c.
Hi ;)
All of the following expressions are equivalent to 12w + 6, except:
A) -1 (12w-6)
Because that is simplified to -12w+6.
Hope this helps u :)
Good luck !!
