    MHB COVID-19 in a Small Town: Probability of Infection

    Kindly assist with these questions: Data showed that 22% of people in a small town was infected with the COVID-19 virus. A random sample of six residents from this town was selected. 1) What is the probability that exactly two of these residents was infected? 2) What is the probability that at...

    MHB Determine the values of f(6) and g(6)

    So, we can conclude that (x+1) is the only common factor. Wow! You are the best. Thanks for taking me through this process. I surely learned a lot

    MHB Determine the values of f(6) and g(6)

    Substituting p(a)=0 and q(a)=0 in the equation will give 0=2 (this cannot be true)

    MHB Determine the values of f(6) and g(6)

    So (x-a) is a factor!

    Therefore p(a)= (x-a)r(x)=0

    MHB Determine the values of f(6) and g(6)

    (a-6)p(a)=(a-3)q(a)-2 Thanks so much but I couldn't make headway with the substitution.

    MHB Determine the values of f(6) and g(6)

    If we divide (x-6)(x+1)p(x)=(x-3)(x+1)q(x)+2(x+1) by (x+1) We will get (x-6)p(x)=(x-3)q(x)+2 p(x)=q(x)+2 ?? I am also struggling to see any common factor in the equation Thanks!

    MHB Determine the values of f(6) and g(6)

    Thanks I like Serena, So since x+1 is a common factor, therefore g(-1)= (-1-3)(-1+1)q(x)=0 g(-1)=0 Therefore f(-1)= 0+2(-1)+2=0 Thus x+1 is a common factor of both functions since the remainder equal zero. I will appreciate if you can confirm that this is order. Thank you.

    MHB Determine the values of f(6) and g(6)

    Thanks a lot! I am grateful for your help. How do I determine if functions p(x) and q(x) have a common factor using f(x)=g(x)+2x+2?

    MHB Determine the values of f(6) and g(6)

    Thanks a lot! when I substituted x=6 into (x-6)(x+1)(px), f(x)=0. This make g(x)=-2x-2. I'm sure this is wrong. - - - Updated - - - I meant my substitution is wrong!

    MHB Why is Angle C Assumed to be Acute and What is the Value of Sin C in ∆ABC?

    Thanks a lot! I mean't to say it is a right triangle because I used Trig ratio. I am sorry the diagrams that were included in my attempt to solve the second part of the question are not displaying in the thread. I will make another attempt to attached the diagrams. Your efforts is highly...
