4) a. Sin 32 = x/4
= (sin 32)(4) = x
b. Cos 65 = 4.5/x
x = 4.5/Cos 65
About 379.1666666666666
The 6 is repeating. Or about 379 if your rounding.

Answer:
0.3907
Step-by-step explanation:
We are given that 36% of adults questioned reported that their health was excellent.
Probability of good health = 0.36
Among 11 adults randomly selected from this area, only 3 reported that their health was excellent.
Now we are supposed to find the probability that when 11 adults are randomly selected, 3 or fewer are in excellent health.
i.e. 
Formula :
p is the probability of success i.e. p = 0.36
q = probability of failure = 1- 0.36 = 0.64
n = 11
So, 



Hence the probability that when 11 adults are randomly selected, 3 or fewer are in excellent health is 0.3907
