Which of the following is an irrational number?

tamaranim1 [39]

Answer:

The correct option is;

0.100100010000...

Step-by-step explanation:

An irrational number in mathematics are the subset of real numbers that are not rational numbers such as √2, π, e. As such it is not possible to express an irrational number as a ratio of two integers, or expressed in the form of a simple fraction.

The decimal portion of the expression of an irrational number are non periodic and they do not terminate. Transcendental, which are non algebraic, numbers are all irrational numbers

In the question, the number 0.100100010000... has non terminating non recurring decimals and is therefore an irrational number.

The university police department must write, on average, five tickets per day to keep department revenues at budgeted levels. Su

Answer:

3.566%

Step-by-step explanation:

The probability formula for a poisson distribution is:

$P( k )=\frac{\lambda^{k}e^{-\lambda}}{k!} \\$

λ is the average of events

e is the euler's number

k is the number of events you want to know the probability

For this :

λ = 8.9 (on average the number of tickets is 8.9 per day)

k = 4 (you need to find the probability that exactly 4 tickets are written per day)

$P( k=4 )=\frac{8.9^{4}e^{-8.9}}{4!}=0,03566 =3.566\%$

Answer & Step-by-step explanation:

The formula is given in the middle. You are supposed to insert the value of x into this formula to find the value of y (like in the first given example):

$x=-2\\y=2(-2)+5\\y=-4+5\\y=1$
