Leokris [45]

Answer:

a) Identify the variable of interest.

Ages of the residents

b) Describe the center and spread of the population of Sunshine City.

Center of the population of Sunshine city = 63 years

Spread of the Population of Sunshine city = 17 years

c) Describe the center and spread of the random sample of Sunshine City

residents taken.

Center of the random sample of Sunshine city = 61.4 years

Spread of the random sample of Sunshine city = 19 years

What shape does it probably have:

It has a skewed(left) shape

Step-by-step explanation:

a) Identify the variable of interest.

Ages of the residents

The center of a distribution tells us about the Mean or Median of the distribution

The spread of a distribution tells us about the standard deviation of the population

b) Describe the center and spread of the population of Sunshine City.

Center of the population of Sunshine city = Mean of the population of Sunshine city = 63 years

Spread of the Population of Sunshine city = Standard Deviation of the population = 17 years

c) Describe the center and spread of the random sample of Sunshine City

residents taken.

Center of the random sample of Sunshine city = 61.4 years

Spread of the random sample of Sunshine city = 19 years

What shape does it probably have:

It has a skewed(left) shape

This is because the mean is farther out to the left side of the tail of the distribution.

Rearrange the equation so xxx is the independent variable. Pls Help :)<br><br>−5x−4y=−8
S_A_V [24]

The rearranged expression will be equal to y = (-5/4)x + 2.

<h3>What is an expression?</h3>

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

<h3 />

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given expression will be rearranged as below:-

−5x−4y=−8

Solve the above expression for the value of y and the x variable will become independent.

−5x−4y=−8

Take -5x to the right side of the equation.

-4y = 5x - 8

Divide the equation by -4.

y = ( -5 / 4 )x + 2

Therefore, the rearranged expression will be equal to y = (-5/4)x + 2.
