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.

Use the Pythagorean theorem to find b .
AysviL [449]

Answer:

b = 5

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

12^2 + b^2 = 13^2

144+b^2 =169

Subtract 144 from each side

144-144+b^2 = 169-144

b^2 = 25

Take the square root on each side

sqrt(b^2) = sqrt(25)

b = 5

Solve for v . =−16 − 47v
Schach [20]
I'm pretty sure this is what you have to do;
v=-16-47v
add 47v on the other side of the equal sign
47v=-16
then divide 47 on each side of the equal sign
47v÷47v=1v or just v
-16÷47=-0.3
v=-0.3
I think this is right.
Hope this helps
