Multiply to get the sums and add them together to get your answer.
Answer:
No, the given procedure doesn't result in a binomial distribution.
Step-by-step explanation:
We can identify if a given procedure results in binomial distribution by observing whether these four conditions are met or not.
Condition 1: Each observation should be independent, it must not depend on the result of previous observation.
Condition 2: The probability of success should stay same from trial to trial.
Condition 3: n is fixed (the number of observations)
Condition 4: There are only two outcomes success or failure.
Surveying 2828 people to determine which statistics courses they have taken.
Condition 3 is satisfied since n is fixed
Condition 1 is satisfied since each observation is independent
Condition 4 is not satisfied since there can be more than 2 answers from the people (statistics courses can be many).

By the Segment Addition Postulate, SAP, we have
XY + YZ = XZ
so
YZ = XZ - XY = 5 cm - 2 cm = 3 cm
10.
M is the midpoint of XZ=5 cm so
XM = 5 cm / 2 = 2.5 cm
11.
XY + YM = XM
YM = XM - XY = 2.5 cm - 2 cm = 0.5 cm
12.
The midpoint is just the average of the coordinate A(-3,2), B(5,-4)
Answer: M is (1,-1)
You'll have to plot it yourself.

For distances we calculate hypotenuses of a right triangle using the distnace formula or the Pythagorean Theorem.
Answer: AB=10
M is the midpoint of AB so
Answer: AM=MB=5

B is the midpoint of AC. We have A(-3,2), B(5,-4)
B = (A+C)/2
2B = A + C
C = 2B - A
C = ( 2(5) - -3, 2(-4) - 2 ) = (13, -10)
Check the midpoint of AC:
(A+C)/2 = ( (-3 + 13)/2, (2 + -10)/2 ) = (5, -4) = B, good
Answer: C is (13, -10)
Again I'll leave the plotting to you.
