Discussion:

A. = 3.5 * (1/5) and 3.5 is NOT an integer

B. = 6 * (1/5) and 6 is an integer

C. = (1/4)* (1/5) and (1/4) is NOT an integer

D. = (1/5)*(1/5)* (1/5) = (1/25)(1/5) and )1/25) is NOT an integer

Situation D: Suppose that, in a one-minute period during an electrical storm, the number of lightning strikes on a radar antenna

Crank

Answer:

21.77% probability that the antenna will be struck exactly once during this time period.

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 interval.

In this question:

$\mu = 2.40$

Find the probability that the antenna will be struck exactly once during this time period.

This is P(X = 1).

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

$P(X = 1) = \frac{e^{-2.40}*2.40^{1}}{(1)!} = 0.2177$

21.77% probability that the antenna will be struck exactly once during this time period.

Peanuts are priced at 3.38 per pound. Derek buys a sack of peanuts for 15.82. Which measurement is a reasonable estimate of the

Rashid [163]

Given :

Price per pound of peanuts is, P = $3.38 .

Derek buys a sack of peanuts for $15.82.

To Find :

The weight of the peanuts that are in the sack.

Solution :

Let, weight of peanuts that are in the sack are x.

So, $x = \dfrac{15.82}{3.38}\\\\x = 4.68\ pounds$

Therefore, number of pounds in the sack is 4.68 pounds.
