An integer is a whole number (not a fraction) that can be positive, negative, or zero. Therefore, the numbers 10, 0, -25, and 5,148 are all integers. Unlike floating point numbers, integers cannot have decimal places.

Hope this helps. :) have an amazing day/night

Answer:

a) We have the mean number of events is interval(5.3 events in 10 minutes), which constitutes the Poisson probability distribution.

b) 5.3

c) 5.3

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.

a. What probability distributions' properties is this?

We have the mean number of events is interval(5.3 events in 10 minutes), which constitutes the Poisson probability distribution.

b. What is the expected value of the random variable x?

It is known that the mean number of occurrences in ten minutes is 5.3.

So the mean is $\mu = 5.3$

c. What is the variance of the random variable x?

In the Poisson probability distribution, the variance is the same as the mean. So the variance is 5.3.

An anthropology article presents a hypothetical situation that could be described by a linear programming model. Suppose a popul

solong [7]

Answer:

The minimum labor = 270 hours and it is obtained when 0 units of plants and 18 animals are collected.

Step-by-step explanation:

We assume that x should represent the number of units of plants

Also y to represent the number of animals.

So, minimze (z) = 30 x + 15 y

Subject to:

30 x + 20 y ≥ 360

10 x + 25 y ≥ 300

y ≤ 8

0 ≤ x ≤ 25

0 ≤ y ≤ 25

Changing the above linear inequalities into linear equation; we have:

30 x + 20 y = 360

10 x + 25 y = 300

y = 8

The graph for the above discussion can be located in the attached diagrammatic expression below:

NOW, the corner points (0,18),(0,25),(25,25), and (25,8) can be calculated from the graph. From the diagram, the corner point $[\frac{60}{11} , \frac{108}{11} ]$ can be found by solving the system.
