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

Given α and β are Supplementary. Show the necessary steps.

user100 [1]

Answer:

$\alpha = 108\degree, \: \beta = 72\degree$

Step-by-step explanation:

α and β are Supplementary (given)

$\therefore \alpha + \beta = 180\degree.... (1)$

It is given that:

$\alpha= \frac{3}{2} \beta$

Plugging the value of α in equation (1), we find:

$\frac{3}{2} \beta + \beta = 180\degree$

$\therefore \frac{3+2}{2} \beta = 180\degree$

$\therefore \frac{5}{2} \beta = 180\degree$

$\therefore \beta = 180\degree\times \frac{2}{5}$

$\therefore \beta = 72\degree$

$\implies \alpha= \frac{3}{2} \times 72\degree= 108\degree$

So,

$\alpha = 108\degree, \: \beta = 72\degree$

Step-by-step explanation:

24 miles/6 days 5280 ft/1 mile

you would then multiply 24 by 5280 to get 126760

and afterwards you would divide 126760 by 6 to get 21120 ft per day
