Hey can you please help me posted picture of question
1 answer:
Total number of boys = 200
Number of left handed boys = 50
If a students is known to be a boy, the probability that he is left handed will be equal to = (Number of left handed boys) / (Total Number of boys)
So, If a students is known to be a boy, the probability that he is left handed will be =
Thus, the correct answer is option B

Answer: -3.
Step-by-step explanation:
We are given that : (1)
It means that f(x) and g(x) are proportional.
[Equation of direct variation: y=kx , where k= proportionality constant.]
From the given graph ,
At x= -3 , f(x)=1 and g(x) =-3
Put value of x=-3 in (1) , we get
[∵ f(x)=1 and g(x) =-3]
i.e. The value of k = -3
Hence, the correct answer is -3.
