4 x (n + 20), pretty simple. :)
Weird question xD
You have to use the Pythagorean theorem on this one.
a^2 + b^2 = c^2
11^2 + h^2 = 12^2
121 + h^2 = 144
h^2 = 23
h = 4.79583
Rounded to the nearest tenth

Answer:
The test statistic is 
Step-by-step explanation:
We are interested in determining whether or not the proportion of the student who experience anxiety during the exam is significantly more than 80%.
At the null hypothesis, we test if the proportion is 80%, that is:

At the alternate hypothesis, we test if the proportion is more than 80%, that is:

The test statistic is:

In which X is the sample mean,
is the value tested at the null hypothesis,
is the standard deviation and n is the size of the sample.
80% is tested at the null hypothesis:
This means that 
A random sample of 100 students was taken. Eighty-five of the student in the sample experienced anxiety during the exam.
This means that 
The test statistic is



The test statistic is 
Answer:
Step-by-step explanation:a/
slope m = [f(x)-f(3)]/(x-3)
b/
tangent y - f(3) = [lim m ,as x-->3](x-3)
