Yes, because the mixed numbers could be a negative number like -1 1/2 plus -2 1/2 which would be -4 and -4 is less than one.
Answer:

Where t represent the time in years
For this case this model follows the general model given by:

Where a = 140 represent the initial amount of bisons and y the number of bisons after t years and b = 2.7 represent the growth rate
For this case we want to find the value of y when t =30, and if we replace the value of t =30 in our function we got:

And if we round to the nearest whole number we got 189 bisons after 30 years
Step-by-step explanation:

Answer:
D
Step-by-step explanation:
Lets look at the numbers
sqrt(4) = 2 which is a rational number
sqrt(5) cannot be simplified, it is an irrational number
-6/5 a ratio of integers, which is the definition of a rational number, so it is a rational number
3.5 = 35/10 a ratio of integers, which is the definition of a rational number, so it is a rational number
.555555 = 5/9 a ratio of integers, which is the definition of a rational number, so it is a rational number
Rational numbers: sqrt(4), -6/5, 3.5 , .5555(repeating)
Irrational numbers: sqrt(5)
