What type of number is 4π?

shutvik [7]

Answer:

It would be an irrational number.

Because of π, or pi, it has no end, no pattern, and that multiplied by four will still be irrational. It can not be represented on a number line or infinite decimal expansion.

The number of phone calls that Actuary Ben receives each day has a Poisson distribution with mean 0.1 during each weekday and me

Dovator [93]

Answer:

There is a 0.73% probability that Ben receives a total of 2 phone calls in a week.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

$e = 2.71828$ is the Euler number

$\mu$ is the mean in the given time interval.

The problem states that:

The number of phone calls that Actuary Ben receives each day has a Poisson distribution with mean 0.1 during each weekday and mean 0.2 each day during the weekend.

To find the mean during the time interval, we have to find the weighed mean of calls he receives per day.

There are 5 weekdays, with a mean of 0.1 calls per day.

The weekend is 2 days long, with a mean of 0.2 calls per day.

So:

$\mu = \frac{5(0.1) + 2(0.2)}{7} = 0.1286$

If today is Monday, what is the probability that Ben receives a total of 2 phone calls in a week?

This is $P(X = 2)$ . So:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 2) = \frac{e^{-0.1286}*0.1286^{2}}{(2)!} = 0.0073$

There is a 0.73% probability that Ben receives a total of 2 phone calls in a week.

For males in a certain town, the systolic blood pressure is normally distributed with a mean of 120 and a standard deviation of

KengaRu [80]

Answer:

$G=93\ to\ 147$

Step-by-step explanation:

From the question we are told that

Mean $x= 120$

Standard deviation $\sigma= 9$

Percentage for men =99.75%

Generally the empirical rule 68%,95% and 99.7% of data value lay b/w 1,2,3 standard deviation of mean

Standard deviation n= 9

Mean x= 120

Generally the interval of systolic blood pressure for middle 99.7 of male G is mathematically given as

$G=Mean \pm 3* \sigma$

$G=120 \pm 3*9$

$G=93\ to\ 147$
