Answer:

probability sample

Step-by-step explanation:

Hello! All elements of the population have a probability greater than zero to be selected, and this probability of inclusion is known precisely. Examples: The census of a country, the set of addresses of households in a population or the list of clients of a company

Answer:

This is an exponential growth equation of the form:

f(t) = A*(r)^t

Where:

A is the initial quantity of something, suppose that is the population of some kind of animal

r is the rate of growth

t is the variable, usually represents a unit of time.

f(t) is the population of the animal at the time t.

For this question, we have the equation:

b(t) = 1200*(1.8)^t

And this represents the population of a kind of bacteria as a function of time.

a) 1200 is the initial population of the bacteria.

b) the 1.8 is the rate of growth.

c) Now we have the equation:

b(t) = 1000*(1.8)^t

In this case, 1000 will represent the initial population of bacteria for this second study.

And the difference between the 1200 for the first study, and the 1000 for this second study, means that for the first study the initial population of bacteria was larger. (200 units larger).

If the odd against the occurence of an event be 4:7 find the proabilty of the occurence of the event.
Alla [95]

Answer:

Probability = \frac{7}{11}

Step-by-step explanation:

Given

Odds:Occurence = 4:7

Required

Determine the probability of the occurrence

First, we need to get the total of the ratio

Total = 4 + 7

Total = 11

Next, is to calculate the required probability as follows;

Probability = \frac{Occurrence}{Total}

Probability = \frac{7}{11}

<em>Hence, the required probability is </em>

Probability = \frac{7}{11}

A box contains 9 Identical glass spheres that are used to make snow globes. The spheres are tightly packed. They are held in a 1
wariber [46]
Because the balls or spheres are tightly packed in a cube, their radius is approximately equal to 2 ft. The volume of a sphere is calculated through the equation,
                                           V = 4/3πr³
Substituting the known radius,
                                           V = 4/3π(2 ft)³
                                           V = 33.51 ft³
The 9 spheres will have a total volume of 301/59 ft³ which is also equal to 521152.52 in³.
