Answer: The answer is AB.
Step-by-step explanation: We are given four blood types and also the number of males and females having each of the blood type. We are to decide the blood type that is independent of the gender.
We can see that the difference between the number of males and females in the blood types A, B and O are large.
Only in the blood type AB, the difference is very small, i.e., the number of males and females having AB blood type is more or less same. So, we can conclude that AB is independent of the gender.
Thus, AB is the correct answer.
Answer:
$34.30
Step-by-step explanation:
Use the equation:
F=P(r)
F=final price
P=principal (starting) amount
r=rate, normally a percent and has to be converted to a decimal
**Since this problem asks us to go down, there is no 1+r. That's when it gives us the final price and asks us to find the original.
Plug in the values: F = 49(.7)
F=$34.30 (don't forget the $ sign)
