Answer:

3 / 10

Step-by-step explanation:

Total = 30 times

n ( T ) = 30

Green = 9

n ( G ) = 9

To find : Probability of Green [ P ( G ) ]

Formula : -

P ( G ) = n ( G ) / n ( T )

P ( G ) = 9 / 30

9 = 3 x 3

30 = 3 x 10

P ( G ) = ( 3 x 3 ) / ( 3 x 10 )

P ( G ) = 3 / 10

Hence,

the experimental probability that the next time the spinner is spun, it lands on green is 3 / 10.

B
If it landed on green 9/30 times that is the ratio.
3/10= 9/30

During the period from 1790 to 1930, the US population P(t) (t in years) grew from 3.9 million to 123.2 million. Throughout this
alex41 [277]

Answer:

Step-by-step explanation:

Given that during  the period from 1790 to 1930, the US population P(t) (t in years) grew from 3.9 million to 123.2 million. Throughout this period, P(t) remained close to the solution of the initial value problem.

\frac{dP}{dt} =0.03135P =0.0001489P^2, P(0) = 3.9

a) 1930 population is the population at time t = 40 years taking base year as 40

We can solve the differential equation using separation of variables

\frac{dP}{0.03135P – 0.0001489P^2 } =dt\\\frac{dP}{-P(0.03135 – 0.0001489P } =dt

Resolve into partial fractions

\frac{31.8979}{P} -\frac{0.00474}{0.0001489P-0.03135}

Integrate to get

ln P -0.00474/0.0001489  (ln (0.0001489P-0.03135) = t+C

ln P -31.833  (ln (0.0001489P-0.03135) =t+C

\frac{P}{( ( (0.0001489P-0.03135)^{31.833}  } =Ae^t

Limiting population would be infinity.

A city has a population of 400,000 people. Suppose that each year the population grows by 6.25%. What will the population be aft
Elena L [17]
6.25%=0.0625

P(t) = Initial Population * (1 + rate)^t

P(t) = 400,00*(1+0.0625)^t
P(t)= 400,00*(1+0.0625)^15
