The population of a community is known to increase at a rate proportional to the number of people present at time t (in years). In 4 years, the population has increased to 4,000 from an initial population of 2,000. What is the formula for the population P(t) at time t?

The population of a community is know to increase at a rate proportional to the number of people present at time t. If an initial population's P0 has doubled in 5 year's.

Step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
