Answer:

Standard deviation = 4

Step-by-step explanation:

Given the following data;

Mean = 25

Variance = 16

To find the standard deviation;

Mathematically, standard deviation is given by the formula;

Standard \; deviation = \sqrt{variance}

Substituting into the formula, we have;

Standard \; deviation = \sqrt{16}

Standard deviation = 4

Variables: x, y, z (we should multiply them and put them together )
x \times y \times z = xyz
Then coeffitions, we should multiply them
3 \times 5 \times 7 = 105
Now put coeffitions before variables:
105 \times xyz = 105xyz

ameson downloaded one digital song for $1.45, two digital songs for $2.90, and 5 digital songs for $7.25. Enter and solve an equ
kap26 [50]

The equation is c = 1.45 n

Total cost of 25 songs is $36.25

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

  • m is the rate of change
  • b is the initial value (value y at x = 0)

∵ The cost of downloaded one digital song is $1.45

∵ The cost of downloaded two digital song is $2.90

∵ The cost of downloaded five digital song is $7.25

- There is a linear relation between the cost of downloading

   the songs and the number of songs

∵ 2.90 = 2 × 1.45

∵ 7.25 = 5 × 1.45

∴ The total cost of downloaded songs is the product of the number

   of songs and the cost per song

∵ The cost per song is 1.45

∵ n is the independent variable

∴ n represents the number of songs

∵ c is the dependent variable

∴ c represents the total cost of n songs

- Now we can write the linear equation

∴ c = 1.45 n

The equation is c = 1.45 n

∵ 25 digital songs downloaded

∴ n = 25

∵ c = 1.45 n

∴ c = 1.45(25)

∴ c = 36.26

Total cost of 25 songs is $36.25
