Image relating to the question can be found in the attachment below :

Answer:

4/9

Step-by-step explanation:

From the picture :

The nine chips are : 1, 2, 3, 4, 5, 6, 7, 8, 9

Even chips = 2, 4, 6, 8

Probability = number of required outcomes / (number of total possible outcomes)

Probability of drawing a chip with an even number :

P(even number) = number of even chips / total number of chips

P(even number) = 4 / 9

kifflom [539]

Answer:

2.73 million people per year

Step-by-step explanation:

Turn sentences into coordinates/points:

In 2000, 281.4 million people

  • (x₁, y₁) = (2000, 281.4)

In 2010, 308.7 million people

  • (x₂, y₂) = (2010, 308.7)

Rate of population per year:

\sf \dfrac{y_2 - y_1}{x_2- x_1} \ \  where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points

\rightarrow \sf \dfrac{308.7-281.4}{2010-2000}

\rightarrow \sf 2.73 \ million \ people
