Answer:
sina
Step-by-step explanation:
Using the cofunction identity
cos(90 - x) = sinx , then
cos(120 - (30 + a) )
= cos(120 - 30 - a)
= cos(90 - a)
= sina
No, there are the same y values. View the y value, 1.
Good luck!
Number of green balls = 87
Number of red balls = 41
So total number of balls = 128
Probability formula = number of events / number of possible outcomes.
So, the probability that a ball randomly selected will be a green ball will be

equals 0.6796875 converting to nearest hundredth as 0.68
Answer:
