that is pretty close to a 45 degree angle so i would say about 33
First find the missing side...
11^2 + a^2 = 20^2
121 + a^2 = 400
400 - 121 = a^2
a^2 = 279
a = 16.7
A = 16.7, B = 11, C = 20
20 - 16.7 = 3.3
3 x 11 = 33
is the number of minutes a student was allowed to spend on the exam
is the students score out of 100
The slope of the regression line is
The intercept is
The equation of the regression line is
We would expect a score of 100 as the test has a total score of 100 marks.
H0: mu = 5
Ha: mu > 5
A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) upon testing.
It is expressed using the equality sign.
An alternate hypothesis is also a statement from a population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected.
It is expressed using any of the inequality signs.
B. because there are too many side lengths to be a triangle
