Rotating a <em>point </em>by 90 degrees <em>counterclockwise</em> would make the y become x and switch it's negative/positive value, and make x the y.
Ex: (x,y) would become (-y,x)
Answer:
Probability = 0.01531
Step-by-step explanation:
Prob (Getting 92 out of 100 germinated seeds) follows binomial probability distribution.
N = Number of seeds = 100. r = Number of success (germination) = 92
r = No. Success = Seed germination, Prob (Success) ie P = 85% = 0.85 , Prob (non success ie non germination) ie Q = 1 - 85% = 15% = 0.15
Probability = N c r . (P)^r . (Q)^(n-r)
= 100c92 (0.85)^92 (0.15)^8
= 186087894300 (0.000000321026708) (0.000000256289062)
= 0.01531 {Approx}
Noel : 90 minutes a day for 6 days....90 * 6 = 540 minutes
Tyra : 60 minutes a day for 8 days....60 * 8 = 480 minutes
difference of : 540 - 480 = 60 <==
