Answer:
7.87 years
Step-by-step explanation:
#First we determine the effective annual rate based on the 9% compounded semi annual;

#We then use this effective rate in the compound interest formula to solve for n. Given that the principal doubles after 2 yrs:

Hence, it takes 7.87 years for the principal amount to double.

Answer: guess it your self
Step-by-step explanation:
P(800)=775
800p=775
800p/800=775/800
p=0.96875
rounded = 97 percent
Assuming uniform distribution and independence, then
<span>P(1st number less than 8 and 2nd number less than 8) = </span>
<span>P(1st number less than 8)*P(2nd number less than 8) = </span>
<span>(7/12)*(7/12) = about 34%</span>
