Answer:
12.699
Step-by-step explanation:
i think if you do 26-22.4, you get the leg of the small triangle which is 3.6
then do Pythagorean theorem
3.6^2 + x^2 = 13.2^2
12.96 +x^2 = 174.24
174.24-12.96
x^2 = 161.28
take square root
x = 12.699
A binomial probability density function should be used to represent the probability
<h3>How to determine the type of
probability density?</h3>
The given parameters are:
- Proportion that plays sport, p = 32%
- Number of students selected, p = 50
- The probability, P = (x ≤ 15)
The proportion that plays sport indicates that
68% of the students do not play sport
So, we have two events, which are
- Play sport
- Do not play sport
When there are two possible events, then the binomial probability density function should be used

Answer:
The given statement:
The expression cos^-1 (3/5) has an infinite number of values is a true statement.
Step-by-step explanation:
We are given a expression as:
Let us equate this expression to be equal to some angle theta(θ)
i.e.
Let
As we know that the limit point of the cosine function is [-1,1]
i.e. it takes the value between -1 to 1 and including them infinite number of times.
Also,
-1< 3/5 <1
This means that the cosine function takes this value infinite number of times.
That is there exist a infinite number of theta(θ) for which:
i.e. the expression:
has infinite number of values.
Where are the triangles :)
