M=18
explication: both of the angles are 90 degrees, 90-33=57, 3(18)+3=57
I think the answer will be A
Answer:
75.2
Step-by-step explanation:
multiple 8 by 9.4
Answer:
Step-by-step explanation:
you have two supplementary angles,
both added up=180
7y+5y=12y
12y=180y=15
angle DBC=7y=15*7=105
Answer: Our required probability is 0.167.
Step-by-step explanation:
Since we have given that
n = 15
Probability of success p = 80% = 0.8
Probability of failure q = 20% = 0.2
We need to find the probability that at least fourteen will work.
So, by Binomial distribution, we get that

Hence, our required probability is 0.167.
