Answer:
Binomial, with 
Step-by-step explanation:
For each student, there are only two possible outcomes, either they own a cellphone, or they do not. The probability of a student in the sample owning a cellphone is independent of whether other students own a cellphone or not. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution:
Probability of exactly x sucesses on n repeated trials, with p probability.
90% of students now own a cell phone.
This means that 
Fifteen students are to be selected at random from a large university.
This means that 
What is the appropriate distribution for X?

Answer:

**The picture is not accurate for this problem.
Step-by-step explanation:
I would use Pythagorean Theorem to setup two equations since there are two triangles with no angle information.
Let 
where 
is equal to the first partition of 
(reading from left to right) and 
is equal to the second partition of (reading from left to right).
We have the following system to solve:
I will use elimination to first solve for .
Subtract the equations:
Factor both sides using 
:
Simplify inside the 
.
Divide both sides by 9:
Divide both sides by 11:
Simplify both sides:
Add 99 on both sides:
Divide both sides by 2:
Now go to either equation we had in the beginning to find 
.

Answer: x = 7
Step-by-step explanation: In order for a parallelogram to be a square, the angles at the corners must be 90 degrees, and the diagonals that bisect the corner angles must be 45 degrees.
4x + 17 = 45 Subtract 17 from both sides.
4x = 28 Divide both sides by 4
x = 7
