Answer:
a)

b) 
c) 
d) 
e) 
Step-by-step explanation:
1) Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
2) Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
3) Part a

4) Part b


5) Part c
![P(X \leq 16)=1-P(X>16)=1-P(X\geq 17) = 1-[P(X=17)+P(X=18)+P(X=19)+P(X=20)+P(X=21)+P(X=22)]](https://tex.z-dn.net/?f=P%28X%20%5Cleq%2016%29%3D1-P%28X%3E16%29%3D1-P%28X%5Cgeq%2017%29%20%3D%201-%5BP%28X%3D17%29%2BP%28X%3D18%29%2BP%28X%3D19%29%2BP%28X%3D20%29%2BP%28X%3D21%29%2BP%28X%3D22%29%5D)

6) Part d
The expected value is:

7) Part e
The variance is given by:

The perimeter of the figure to the nearest tenth is 44.6 units
<h3>Perimeter of a figure?</h3>
The perimeter of a figure is the sum of the whole sides.
Therefore,
A parallelogram has opposite sides equal to each other.
Therefore, the perimeter of the figure is as follows;
The figure combines a parallelogram and a semi circle.
Therefore,
perimeter of the figure = 4 + 14 + 14 + πr
perimeter of the figure = 32 + 3.14 × 4
perimeter of the figure = 32 + 12.56
perimeter of the figure = 44.56
perimeter of the figure ≈ 44.6 units

Answer: I think the answer would be nine. Hear me out
Step-by-step explanation: The left triangle has the angles 5 and 4, so the right answer for the other side would be the angles 8 and x=9.
