Answer:

P (factors of 12) = 5/6

Step-by-step explanation:

The possibilities are 1,2,3,4,5,6

Factors of 12 are 1,2,3,4,6,12

So out of the possibilities rolled

1,2,3,4,6 are factors of 12  (5 of the 6)

P (factors of 12) = 5/6

Answer:

5/6

Step-by-step explanation:

well, 1,2,3,4 and 6 are factors of 12.

and a fair sided dice has 6 sides.

so 5 out of those 6 sides are factors of 12.

The only on that is not is 5

Assume that in the absence of immigration and emigration, the growth of a country's population P(t) satisfies dP/dt = kP for som
Morgarella [4.7K]

Answer:

A) Differential equation for population growth in case of individual immigration is:

\frac{dP}{dt}=kP+r

B) Differential equation for population growth in case of individual emigration is:

\frac{dP}{dt}=kP-r

Step-by-step explanation:

Population growth rate  in the absence of immigration and emigration is given as:

\frac{dP}{dt}=kP--(1)

A) When individuals are allowed to immigrate:

Let r be the constant rate of individual immigration given that r >0.

Differential equation for population growth in this case is:

\frac{dP}{dt}=kP+r

B) In case of individual emigration:

Let r be the constant rate of individual emigration given that r >0.

Differential equation for population growth in this case is:

\frac{dP}{dt}=kP-r

.75x-20= 620 what does x equal rounded to the nearest 100?
vodomira [7]

To solve this, we’ll have to use inverse operations.

Since addition is the inverse to subtraction, we’ll add 20 to 620.

20 + 620 = 640

From there, since division is the inverse of multiplication, we’ll divide .75 by 640.

640/.75 = 853.33333 repeating. We can round this to 853.33, to round to the nearest hundredth.

Therefore, 853.33 would be your answer! You can check this by solving the equation forwards (853.33 x .75 = ~640, 640 - 20 = 620.)

Hope this helps! :)
