If angle I is congruent to angle K find the perimeter of triangle JIK?
1 answer:
The perimeter of a triangle is given by <em>the sum its three sides</em>, then according to the figure above we have that:
Thus, our goal is to find the value of
and by finding it we will get the perimeter of the triangle. If ∠I = ∠K = β, then according to the Law of Sines we have:
Lastly, the perimeter is:
Thus, our goal is to find the value of
Lastly, the perimeter is:

Answer:
For this case we want to test if the the average monthly income of all students at college is at least $2000. Since the alternative hypothesis can't have an equal sign thne the correct system of hypothesis for this case are:
Null hypothesis (H0):
Alternative hypothesis (H1):
And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 200 or no
