Answer: 45

Step-by-step ex

The % sign comes from the Latin Per Cento or 'what part of 100'.

x times 60 parts out of 100 parts equals 27.

This can be written in the language of math as

x (60/100) = 27

x(.6) = 27

x(.6)/(.6) = 27 / (.6)

x = 45

Simplify 425xy⁴/25xy²

beks73 [17]

We have the expression

$\frac{425xy^4}{25xy^2}$

We can already simplify x because it's both on the numerator and denominator

$\frac{425y^4}{25y^2}$

Now we can simplify 425/25 = 17

$\frac{17y^4}{y^2}$

Remember that

$\frac{a^n}{a^m}=a^{n-m}$

Then

$17y^{4-2}=17y^2$

The final result is

$17y^2$

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
