Hello,
f(π/2)=4*sin(π/2)-2=4*1-2=2
f(0)=4*sin(0)-2=0-2=-2

rate=(2+2)/(π/2-0)=8/π

The distance from earth to the moon is about 22^4 miles.The distance from earth to neptune is about 22^7 miles.Which distance is

fiasKO [112]

You are NOT using scientific notation correctly. When you say 22^4 you are saying 22*22*22*22 which equals 234,256. What you should say is Earth to Moon distance = 22 * 10^4 miles. (To be really precise, it should be expressed as 2.2 * 10^5 miles).

Earth to Neptune distance = 2.2 * 10^8 miles.

2.2 * 10^8 / 2.2 * 10^5 = 1,000. So the Earth to Neptune distance is 1,000 times greater than the Earth to Moon distance.

On average, 15 minutes elapse between discoveries of fraudulent corporate tax returns in a certain IRS office. What is the proba

Lyrx [107]

Answer:

The probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered=0.1353

Step-by-step explanation:

We are given that

$\beta=15$

We have to find the probability that more that 30 minutes will elapse before the next fraudulent corporate tax return is discovered.

Using exponential distribution

$P(X> x)=e^{-\frac{x}{\beta}}$

The probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered

$=P(x>30)=e^{-\frac{30}{15}}$

The probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered

$P(x>30)=0.1353$

Hence, the probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered=0.1353
