Which answer choice should I choose? Im thinking C but thinking i am wrong
dexar [7]

Answer:

Natural numbers

Step-by-step explanation:

Rational numbers are numbers which can be expressed in the form a/b ; such that b ≠ 0 ; hence, rational numbers can be certain non-recurring decimal values.

Integer values are numbers which can be written without any fractional component. While natural numbers are characterized as being whole and non-negative

To represent population values, number of people or species cannot be fractional and cannot be negative, hence natural numbers is the best option.

lozanna [386]

Answer:

About 3 times faster

Step-by-step explanation:

Cheetah's speed = 110 km / hr

World 100m sprint record :

Speed of sprinter :

Distance / time

100 m / 9.58s

= 10.438413 m/s

Convert Cheetah's speed to m/s

110 km/hr = (110 * 1000)m / (60 * 60 s)

= 110000 m / 3600 s

= 30.55555 m/s

Number of times cheetah is faster than sprinter :

30.55555 m/s ÷ 10.438413 m/s

= 2.927 times
