So if 6 out of 40 are incorrect, 40-6= 36 must be correct.
In order to gain percentage you do proportions.
36/40 = x/100.
Multiply 36 times 100 then divide by 40, which is 90.
The answer is 90%.
90% of the questions he got were correct.

zimovet [89]

Answer: A) Exponential Function

Step-by-step explanation:

Hi, an exponential function describes best the total number of rabbits in the colony over time, because the population tends to multiply by a specific rate over time.

An exponential function can be described as a growth function, for example in the form:

A = P (1 + r) t  

Where:  

p = original population  

r = growing rate (decimal form)  

t= years  

A = population after t years

Multiply both sides by 2
