A simple dart target has two concentric circles. The larger circle has a radius of 4. The smaller circle has a radius of 2.

The scoring should correspond to the relative difficulty of hitting the inner circle and the outer ring. How many more points should a player receive for landing a dart in the inner circle, as opposed to the outer ring?

The player should receive 3 times as many points.

Step-by-step explanation:

Ratio of the points should be the same as ratio of the areas

(Ratio of radii)² = Ratio of areas

= (4/2)² = 2² = 4

The ratio of the areas:

inner circle to the outer ring is:

1 : 4-1

1 : 3

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
