Suppose that all the people in a country are ranked according to their incomes, starting at the bottom. Let x represent the fraction of the community making the lowest income (0 less than or equals x less than or equals 1 ); x equals 0.4, therefore, represents the lower 40% of all income producers. Let I(x) represent the proportion of the total income earned by the lowest x of all people. Thus, I(0.4) represents the fraction of total income earned by the lowest 40% of the population. The curve described by this function is known as a Lorenz curve. Suppose Upper I (x )equals 0.94 x squared plus 0.06 x. Find and interpret (0.1).

I(0.1) = 0.0154

The 10% of the community with the lowest income hold 1.54% of the total income earned in the community.

Step-by-step explanation:

The Lorenz curve is given by:

If x = 0.1 (representing the 10% of the community with the lowest income), their total aggregate income is given by:

This means that the 10% of the community with the lowest income hold 1.54% of the total income earned in the community.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
