This is a geometric sequence because each term is a constant multiple, called the common ratio, of the previous term. In this case the common ratio, noted as "r", is:

8/-2=-32/8=128/-32=r=-4

The first term is -2

Any geometric sequence can be expressed as:

a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number.

Since we know r and a for this problem already we can say:

a(n)=-2(-4)^(n-1)

A half-gallon carton of organic

kotegsom [21]

Answer:

The price of milk in 5 years = $7.16

Step-by-step explanation:

Given:

Present cost of half-gallon carton milk = $4.45

Increase percentage = 10%

To find the price of milk in 5 years.

Solution:

To find the price of milk in 5 years we will apply the exponential growth formula which is given as:

$F_v=P_v(1+r)^t$

where

$F_v\rightarrow$ final value

$P_v\rightarrow$ present value

$r\rightarrow$ rate of increase in decimals

$t\rightarrow$ time in years.

From the given data, we can plugin values in the equation to calculate final value in dollars after 5 years.

$F_v=4.45(1+0.1)^5$

$F_v=4.45(1.1)^5$

$F_v=4.45(1.61)$

$F_v=7.16$

Thus, price of milk in 5 years = $7.16

Consider a machine that fills 275 gallon tanks of water. The owner discovers that the machine does not always dispense exactly 2

fenix001 [56]

Answer:

(a) The random variable X is a continuous random variable.

(b) The probability density function is shown below.

(c) The probability that a 275 gallon tank gets less than 272.5 gallons or more than 273.8 gallons of water is 0.285.

Step-by-step explanation:

Let the random variable X be denoted as the amount of water filled by the machine in a 275 gallon tank.

(a)

The random variable X is a continuous random variable.

A continuous random variables assumes infinite values. That is, they assume values in a fixed interval. For example, the distance covered by a car.

A discrete random variable assumes fixed definite values. They assume whole number values. For example, number of customers visiting a bank in an hour.

The amount of water in the tank can be any value between 0 to 275 gallon.

Hence, the random variable X is a continuous random variable.

(b)

The probability density function of the continuous random variable X is given as follows:

$0.25;\ 272$
