How do you do letter c?

1056

Step-by-step explanation:

dP/dt = 0.0013P (1 − P/6200)

Euler's method states:

yₙ₊₁ = yₙ + Δt F(tₙ, yₙ)

Substituting:

P(t+1) = P(t) + (1) [0.0013 P(t) (1 − P(t)/6200)]

P(t+1) = P(t) + 0.0013 P(t) (1 − P(t)/6200)

We know that when t=0, P=1000.

P(1) = P(0) + 0.0013 P(0) (1 − P(0)/6200)

P(1) = 1000 + 0.0013 (1000) (1 − 1000/6200)

P(1) = 1001.1

Repeating the pattern, we get P(50) is:

P(50) = 1055.7

Rounded to the nearest whole number, P(50) = 1056.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
