What is the rule for the following geometric sequence? 64, -32,16,-8

Mariulka [41]

The rule is n/(-2)

<h3>What is geometric Progression?</h3>

A geometric progression is a sequence in which any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r.

Given:

64, -32,16,-8

r= 64/-32

r= -2

again, r= -32/16

r= -2

By above we concluded that the common ratio is is -2.

If n is natural numbers for finding geometric progression the rule which defines it n/(-2).

A political campaign wants to estimate the number of adult residents who voted in the last city election. Answer the following.

Svetradugi [14.3K]

Using sampling concepts, it is found that:

a) The best method is: 25 adult residents are randomly selected from the city;

b) The estimate is that 11,536 adults voted in the election.

<h3>What is sampling?</h3>

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

In this problem, the sample will be representative if all adults, no matter if senior or not, homeowners or not are represented, hence the best method is:

25 adult residents are randomly selected from the city;

The estimate of the number of adults that voted is:

14/25 x 20,600 = 11,536.

The cost of using a game facility is $1 for every 12 minutes. Talisa writes the function for the cost per hour as ()=. Explain T

Anna [14]

Using proportions, it is found that Talisa's error was at calculating the cost per minute of the game.

In the function:

The input is x, which is the number of minutes.

The output is f(x), which is the cost of playing the game for x minutes.

Talisa's expression is given by:

$f(x) = 12x$

The cost of using a game facility is <u>$1 for every 12 minutes</u>, hence, the cost per minute is:

$c = \frac{1}{12}$

And the correct expression for the cost is:

$f(x) = \frac{x}{12}$

Hence, it can be seen that Talisa's error was at calculating the cost per minute of the game.
