What is the conditional probability that exactly four heads appear when a fair coin is flipped five times given that the first f

Phantasy [73]

Presumably, the coin tosses are independent of one another, so

$P(\text{exactly 4 heads}\mid\text{first flip is tails})=P(\text{exactly 4 heads})=\dfrac1{2^4}=\dfrac1{16}$

But if the coin flips are not independent, then we can't really say anything about this probability without any more information about how the flips are related...

If your invest $150 at 7% interest compounded annually,in how many years will you have $400?. Give your answer of the nearest te

Answer:

14.5 years.

Step-by-step explanation:

Given that you invest $150 at 7% interest compounded annually. Now we need to find about in how many years will you have $400. Then round the answer ot the nearest tenth of a year.

So plug the given values into compound interest formula.

$A=P\left(1+r\right)^t$

$400=150\left(1+0.07\right)^t$

$\frac{400}{150}=\left(1+0.07\right)^t$

$\ln\left(\frac{400}{150}\right)=\ln\left(1+0.07\right)^t$

$\ln\left(\frac{400}{150}\right)=\ln\left(1.07\right)^t$

$\ln\left(\frac{400}{150}\right)=t\cdot\ln\left(1.07\right)$

$\frac{\ln\left(\frac{400}{150}\right)}{\ln\left(1.07\right)}=t$

$14.4967313882=t$

Which is approx 14.5 years.
