Mean=21.5 (addition of all numbers, divided by total number=129/6)
Median=22.5 (middle number, since there are two add them both and divide)
Mode=24 (most occurring number)
If I understand the second part of the question you would have #3 as your choice.
Answer: 
Step-by-step explanation:
Let the given parabolic mirror opens upwards and vertex=(0,0)
Focus point of the parabolic mirror is located 2 inches from the vertex of the mirror. ∴ p=2
Since, the parabola opens upward, then the equation of the parabola is of the form 
Substitute the value of p=2 in this, we get the equation of the parabolic mirror

Hence, the equation of the parabola that models the cross section of the mirror is 
4 2/3 /2 /5
14/3 / 2/5 cross multiply
7/3 / 1/5 multiply 7 and 5 and 3 and 1
35/3 simplify
11 2/3
Answer:
x = 101°
y = 46°
Step-by-step explanation:
The question tells us that ΔSTU is similar to ΔSVW. This means that the corresponding angles in each triangle are the same. We can write that like this:
∠UST = ∠WSV
∠SUT = ∠W
∠STU = ∠V
We can then fill in the angles we know into these statements.
33° = 33°
101° = x
y = 46°
Now we know the values of x and y.
x = 101°
y = 46°
