Answer:
sinx = √2/3
Step-by-step explanation:
cos2x = 1-2sin²x
5/9 = 1-2sin²x
2sin²x =1-5/9
2sin²x = 4/9
sin²x = (4/9)/2
sin²x = (4/9)*(1/2)
sin²x = 2/9
sinx = √2/3
Answer:
20,000.
Step-by-step explanation:
The first music player has 500 songs stored by 2 GB. So 500/2 is 250. You take 250 and you multiply it by 80 and you get 20,000.
This problem lends itself to the binomial probability approach.
Focus on students who are not secretly robots.
Then P(student is not a robot) = 2/6, or 1/3. Here n=6 and x=2.
Then the desired probability is binompdf(6,1/3, 2), which, by calculator, comes out to 0.329.
1/2x + 3/4y = 4 ....multiply everything by 4
2x + 3y = 16
3y = -2x + 16
y = -2/3x + 16/3
In y = mx + b form, the slope will be in the m position and the y int will be in the b position
y = mx + b
y = -2/3x + 16/3
so ur slope is -2/3 and ur y int is (0,16/3)
