Answer:

a part of the population that represents the entire population

Step-by-step explanation:

A sample simply refers to a smaller group of observation usually drawn from a larger group or a collection of the total possible observation that fits a particular or specific characteristic(population). This smaller group or subset of observation is usually chosen to be representative of the larger group of population. Representative Samples are usually obtained by drawing at random from the population and are very important where using the entire population for a study seems impossible or very expensive or intensive.

Which equation represents a line that is parallel to the line whose equation is 2x + 3y =12
STALIN [3.7K]

Answer:

Choose an equation that has this same slope or the same coefficients of x and y - 2x + 3y.

Step-by-step explanation:

Parallel lines are lines which do not intersect. As a result they have the same slope. The line here is 2x + 3y = 12 which can be rearranged into slope intercept form to find the slope.

2x + 3y = 12

3y = 12 - 2x

y = 4 - 2/3 x

The slope of the line is -2/3. Choose an equation that has this same slope or the same coefficients of x and y - 2x + 3y.

How do I factor this?​
Kay [80]

Answer:

\large\boxed{y^3-6y^2+5y=y(y-1)(y-5)}

Step-by-step explanation:

y^3-6y^2+5y=y(y^2-6y+5)=y(y^2-y-5y+5)\\\\=y[y(y-1)-5(y-1)]=y(y-1)(y-5)

LetX1={5,10,15,20}andY1={5,10,15,20,25}. Using the formal definition of a func-tion, determine which of the following subsets of
tino4ka555 [31]

Answer:

Option b) is the answer

Step-by-step explanation:

A function from X₁ to Y₁ is an object f such that every x in X₁ is uniquely associated with an object f(x) = y in Y₁.

Then

1(b)f={(5,25),(10,5),(15,5),(20,10),(5,25)} is the correct answer.

It follows that

f(5) = 25

f(10) = 5

f(15) = 5

f(20) = 10
