fifth term means replace n = 5 into the f(n)=3(n-3)

f(5) = 3(5-3)

f(5) = 3 * 2

f(5) = 6

answer is 6

The population of a town increased from 3650 in 2006 to 5400 in 2009. Find the absolute and relative (percent) increase.
adell [148]

Answer:

The absolute increase was of 1750.

The relative increase was of 47.95%

Step-by-step explanation:

Absolute increase:

The absolute increase is the final population divided by the initial population.

Initial population: 3650 in 2006

Final population: 5400 in 2010

5400 - 3650 = 1750

The absolute increase was of 1750.

Relative increase:

The relative increase is the absolute increase divided by the initial population, then multiplied by 100(to answer as a percentage):

Absolute increase: 1750

Initial population: 3650

1750/3650 = 0.4795

The relative increase was of 47.95%

i have a square, and place three dots along the 4 edges at random. what is the probability that the dots lie on distinct edges?
olya-2409 [2.1K]

The correct answer is listed as (3/4) * (1/2) = 3/8. The probability that the dots lie on distinct edges is 3/8.

Probability is simply how likely something is to happen. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Sample annual salaries​ (in thousands of​ dollars) for employees at a company are listed. ​(a) Find the sample mean and sample s
Helen [10]

Answer:

Follows are the solution to the given points:

Step-by-step explanation:

The value is attached in the image file please find it.

In point a:

First, we calculate the find the mean,

Formula:

\to Mean (\bar{x}) = \frac{( \sum x)}{n}

                   =\frac{540}{13}\\\\ = 41.54

To calculate the standard deviation, subtract the mean value from all observations then square its value:

SD = \sqrt{\frac{\sum(x-\bar{x})^2}{n-1}} \\   = \sqrt{ \frac{339.2308}{13-1}}

                             = \sqrt{ \frac{339.2308}{12}}\\\\= \sqrt{28.269}\\\\=5.31

please find attached file

In point b:

New x_i = 1 x_i + 0.05 x_i = 1.05 x_i

Calculate new mean:

\to \bar{x} = \frac{\sum x}{n} \\

       =\frac{567}{13} \\\\= 43.62

calculating the standard deviation:

SD = \sqrt{\frac{\sum(x-\bar{x})^2}{n-1}} \\   = \sqrt{ \frac{374.0022}{13-1}}

                             = \sqrt{ \frac{374.0022}{12}}\\\\= \sqrt{31.16}\\\\=5.58

please find attached file

In point C:

Calculate new mean:

\to \bar{x} = \frac{\sum x}{n} \\

       =\frac{47.25}{13} \\\\= 3.46

calculating the standard deviation:

SD = \sqrt{\frac{\sum(x-\bar{x})^2}{n-1}} \\   = \sqrt{ \frac{2.5975}{13-1}}

                             = \sqrt{ \frac{2.5975}{12}}\\\\= \sqrt{0.216}\\\\=0.46

please find attached file

In point d:

for b,

New \bar{x}= 1.05 \bar{x}= 1.05(41.54) =43.62

News= 1.05s= 1.05(5.31)=5.57

for c,

New\bar{x}= \frac{ \bar{x}}{12}= \frac{41.54}{12} = 3.46

New s = \frac{s}{ 12} = \frac{5.31}{12}= 0.44
