The half angle formula is:
sin x/2 = +/- √ (( 1-cos x ) / 2 )
5π/12 = 5π/6 : 2
sin 5π/12 = +/- √(( 1 - cos ( 5π/6)) / 2 )
cos 5π/6 = cos 150° = -√3/2
≈ 0.966 ( this is sin 5π/12 )
Answer:

Here are the numbers of times 11 people ate out last month. 4, 6, 6, 5, 7, 4, 4, 5, 4, 5, 5 Find the modes of this data set. If
Ludmilka [50]
Answer:
4, 5
Step-by-step explanation:
put in order form least to greatest
4,4,4,4,5,5,5,5,6,6,7
whichever number occurs the most is the mode, if two numbers occur the same amount of times, they are bith the mode.
Complete question :
Suppose there are n independent trials of an experiment with k > 3 mutually exclusive outcomes, where Pi represents the probability of observing the ith outcome. What would be the formula of an expected count in this situation?
Answer: Ei = nPi
Step-by-step explanation:
Since Pi represents the probability of observing the ith outcome
The number of independent trials n = k>3 :
Expected outcome of each count will be the product of probability of the ith outcome and the number of the corresponding trial.
Hence, Expected count (Ei) = probability of ith count * n
Ei = nPi
