Consider the chart of Millionaires and Population. If Los Angeles were
proportional to Dubai with respect to population, how many millionaires
should we expect Los Angeles to have? Round your answer to a whole number.

If Los Angeles were  proportional to Dubai with respect to population, how many millionaires  should we expect Los Angeles to have?

The number of millionaires Los Angeles should have equals:

= Proportion of Millionaires in Dubai multiplied by the Population of Los Angeles

= 0.00124 * 4,085,014

= 5,065 millionaires

Step-by-step explanation:

a) Data and Calculations:

City                 Millionaires     Population      Proportion

Los Angeles    11,560            4,085,014       0.00283 (11,560/4,085,014)

Casablanca     6,900            3,752,357        0.00184 (6,900/3,752,357)

Berlin               6,750            3,562,038        0.00189 (6,750/3,52,038)

Dubai               3,570            2,878,344        0.00124 (3,570/2,878,344)

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
