Find sin3A, cos 3A and tan 3A when sin=1/2

Slav-nsk [51]

Answer:

Sin 3A = 1

cos 3A = 0

tan 3 A = undefined

Step-by-step explanation:

$\sin A = \frac{1}{2} \\ \therefore \: \sin A = \sin \: 30 \degree.. \bigg( \because \: \sin \: 30 \degree = \frac{1}{2} \bigg) \\ \therefore \: A = 30 \degree \\ \\ now \\ \sin 3A =\sin (3 \times 30 \degree)= \sin \: 90 \degree = 1 \\ \\ \cos 3A =\cos (3 \times 30 \degree)= \cos \: 90 \degree = 0\\\\ \tan 3A =\tan (3 \times 30 \degree)= \tan \: 90 \degree = \infty$

Assume that a randomly selected subject is given a bone density test. those test scores are normally distributed with a mean of

miv72 [106K]

The randomly selected subject is given bone density test which are normally distributed with mean =0 and standard deviation =1. It means bone density test score is standard normal variable.

The probability that a given score is less than 2.23

P(z < 2.23)

Using z score table to find probability below z=2.23

P(z < 2.23) = 0.9871

The probability that a given score is less than 2.23 is 0.9871

if a bag contains 2 red marbles, 3 blue marbles, 5 yellow marbles and 2 green marbles, if a marble is randomly selected what is

vekshin1

All you need to do here is just find the ratio of red marbles to all of the marbles.
 2 red 
2 red + 3 blue + 5 yellow + 2 green

when you add everything up, you get 2/12, which is equal to 1/6.
