Answer:
The margin of error of his experiment is of 0.1074.
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
.
The margin of error is of:

30 M & M's from a bag, and 3 of them are green.
This means that 
Standard 95% confidence level
So
, z is the value of Z that has a p-value of
, so
.
Margin of error:



The margin of error of his experiment is of 0.1074.
Answer:
AS
Step-by-step explanation:
Answer:
28.8 degrees (rounded)
Step-by-step explanation:
you need to use tan^-1 in order to find x. tan is opposite side / adjacent side.
so...
tan^-1
(50/91) = 28.78661831
Answer:
the first one is scalne the second is isoscles and the third is equailateral
Step-by-step explanation:
scalne- all sides diff lengths
isoscles- two sides same length (remeber the two s in iSoScles)
equaliteral- all sides same length
First, I find it helpful to write the function myself.
There is a set fee of $120, and $5 per <em>n</em> badges.
<em />120 + 5<em>n
</em>
This is a basic model. Now we can see if any match.
f(n) = 5<em>n</em> + 120 matches.
Let me know if you found any errors.
