Explain how populations and variables differ.

Population and variables are different terms, they are very different from each other.

The population is the set or collection of each possible unit that we want to measure. The population might be very large.

For Example: (a). Students who get above 80 marks in Statistics test.

(b). The senior citizen in Australia.

Variable is the descriptive label or number associated with each member of the population. it is the characteristic of the population.

For example: (a). Female Students in those students.

(b) Blood- Pressure patient in that senior citizen.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
