Color blindness is an inherited characteristic that is more common in males than females. Let F represent female, and C represen
malfutka [58]

Answer:

0.513 = 51.3% probability of being a female.

Step-by-step explanation:

We are given the following formula:

P(F \cup C) = P(F) + P(C) - P(F \cap C)

In which:

Event F: Female

Event C: Red-green color blindness.

Probability of a Female

We have to find P(F), which is given by:

P(F) = P(F \cup C) + P(F \cap C) - P(C)

We are given by:

P(C) = 0.039, P(F \cap C) = 0.004, P(F \cup C) = 0.548

So

P(F) = P(F \cup C) + P(F \cap C) - P(C) = 0.548 + 0.004 - 0.039 = 0.513

0.513 = 51.3% probability of being a female.

As we know that 
x=x0*[1/2]n
putting the values 
375=3000*[1/2]n
375/3000=<span>[1/2]n
</span>1/8=<span>[1/2]n
simplify
[1/2]3=</span><span>[1/2]n
by cancelling them
so n=3
so it will take 3 minutes

Question 2
Oliga [24]

Answer:

9

Step-by-step explanation:

you want the trinomial (x*x - 6x + __ ) to be written as a binomial squared.

So we would need to realize that the constant would be equal to (-6/2)^2  =(-3)^2 = 9

We have completed the square.

f(x) = 4*( x - 3)^2  + 20   is now in Vertex Form
