Answer:

Step-by-step explanation:
Using the Pythagorean identity
sin²x + cos²x = 1, then
sinx = 
Note that (
)² = 
sinΘ = 
=
= 
Answer:
6
Step-by-step explanation:
since their are 3 numbers to choose from we do 3! or 3*2*1 which is 6.
Using the binomial distribution, the probabilities are given as follows:
a) 0.37 = 37%.
b) 0.5065 = 50.65%.
c) 0.3260 = 32.60%.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
For this problem, the fixed parameter is:
p = 0.37.
Item a:
The probability is P(X = 1) when n = 1, hence:


Item b:
The probability is P(X = 3) when n = 3, hence:


Item c:
The probability is P(X = 2) when n = 4, hence:

Just add to find X
20 + 60 = 80
-------------------------------------
X = 80
To make sure plug it in
80 - 60 = 20
The equation is true
-----------------------------------------------
x = 80 is your answer
-3x-4<19
19+4=23
3x<23
÷3 ÷3
