Answer:
-27.26 ----------- -52.89 - (-25.63)
135.03 ----------- 49.40 - (-85.63)
-120(2)/(3) ----------- -96(2)/(9) - 24(4)/(9)
-15(3)/(5) ----------- -18(1)/(5) - [-2(3)/(5)]
The slope of the line passing through (1 , 0) and (3 , 8) is 4.
Slope, commonly represented by the letter m, is a value that describes the steepness and direction of a line. The slope of a line is also called its gradient or rate of change.
It is the vertical change in y divided by the horizontal change in x, sometimes called rise over run. The slope formula uses two points,
and
, to calculate the change in y over the change in x.
where




Substituting the values,

Hence, he slope of the line passing through (1 , 0) and (3 , 8) is 4.

Complete Question
A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents, 12 % chose chocolate pie, and the margin of error was given as plus or minus 5 percentage points.What values do
, n, E, and p represent? If the confidence level is 90%, what is the value of
?
Answer:
a
is the sample proportion
is the sample size is 
is the margin of error is 
represents the proportion of those that did not chose chocolate pie i.e 
b

Step-by-step explanation:
Here
is the sample proportion
is the sample size is 
represents the proportion of those that did not chose chocolate pie i.e



is the margin of error is 
Generally
is the level of significance and it value is mathematically evaluated as

Where
is the confidence level which is given in this question as 
So


Do you mean ^2? cause if so... B don't really need crit points to solve, the parabola has a positive slope before x =2
