Answer:
The population in 20 years will be 781.
Step-by-step explanation:
The population of the town can be modeled by the following equation:
In which P(t) is the population after t years, P(0) is the initial population and r is the growth rate, as a decimal.
The initial population of 500 increases by 25% in 10 years.
This means that
We use this to find r.
Applying ln to both sides
So
What will be the population in 20 years
This is P(20)
The population in 20 years will be 781.
Answer:
Step-by-step explanation:
Probability tells us how likely something is to occur. It is found by dividing the favorable outcomes by the total outcomes.
In this question, a favorable outcome is selecting a green dye. The total outcomes are all the dyes.
- Favorable outcomes (green dye): 14
- Total outcomes (all dyes): 20 blue+ 6 red+14 green=40
Reduce the fraction. Both the numerator and denominator can be divided by 2.
This is the probabilty as a fraction. It can also be written as a percent. Divide the fraction, then multiply by 100.
The probablity of selecting a green dye is <u>7/20 or 35%</u>
