Answer: Hello there!
A model to see the growth of a certain population is the exponential model.
If the initial population is P, then the model can be written as
Where t is the time, and r is growth rate.
and f(0) = P
Then we want to know the time needed for the initial population to be doubled, this is f(x) = 2P, where x is the time that we want to find.
then
then x= ln(2)/r
Answer:
C
Step-by-step explanation:
x axis is the horizontal line, so count positive 6, not negative, from there. Then go 3 upwards since its positive 3 :)
A possible value could be 21.16

Answer:
Winning probability is
Step-by-step explanation:
Favourable outcomes to win are 3 and 6.
Total outcomes are six in fair dice.
So , probability of winning some money ==
To win $20*3 or $20*6 favourable outcome is 1 (3 and 6 respectively)
Thus probability =
