Answer:
y = ax + b
This line passes (0,0) => b = 0
This line passes (10,60) = > 10a =60 => a = 6
=> y = 6x
The formula states that:
Faces + Vertices - Edges = 2
So 21 + V - 49 = 2 => V = 2+49-21 = 30
Answer A!
<h2>
Answer with explanation:</h2>
Given : The probability that telephone bills mailed to house-holds in Hong Kong are incorrect.=0.01
<h2>
Binomial distribution :-</h2>

If a sample of 10 bills is selected, then the probability that at least one bill will be incorrect :-

Hence, the probability that at least one bill will be incorrect =0.6513
<h2>
Poisson distribution: </h2>

Mean : 
Then , If a sample of 10 bills is selected, then the probability that at least one bill will be incorrect :-

Hence, the probability that at least one bill will be incorrect =0.6321
