Which equation of a line is written in slope-intercept form?
2 answers:
Answer:
y = mx+c
Step-by-step explanation:
Slope refers to measure of steepness of a line.
For a function of form f(x), slope is equal to f'(x) .
Intercepts:
x-intercept refers to a point at which the graph intersects the x-axis.
y-intercept refers to a point at which the graph intersects the y-axis.
If m is the slope of line and c is y-intercept then slope of line is
For example if slope of a line is 2 and y-intercept is 5 then equation of slope becomes

Answer:
The 95% confidence interval for the fraction of all shoppers during the year whose visit was because of a coupon they'd received in the mail is (0.2016, 0.2694).
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 z-score that has a p-value of .
A store randomly samples 603 shoppers over the course of a year and finds that 142 of them made their visit because of a coupon they'd received in the mail.
This means that
95% confidence level
So , z is the value of Z that has a p-value of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the fraction of all shoppers during the year whose visit was because of a coupon they'd received in the mail is (0.2016, 0.2694).
