Answer:
y=Ae^(1.25t)
Step-by-step explanation:
From the expression y=Ae^kt
After two days of the experiment, y = 49 million, t=2
After four days of the experiment, y= 600.25 million, t=4
A is the amount of bacteria present at time zero and t is the time after the experiment (in days)
At t=2 and y =49
49=Ae^2k…………….. (1)
At t=4 and y = 600.25
600.25=Ae^4k………… (2)
Divide equation (2) by equation (1)
600.25/49=(Ae^4k)/(Ae^2k )
12.25=e^2k
Take natural log of both sides
ln(12.25) =2k
2.505 =2k
k=1.25
The exponential equation that models this situation is y=Ae^(1.25t)
The correct answer in this case would be A. There is only 1/8th percent chance of the spinner landing on 4.

Answer:
P(King) = 4/52 = 1/13
Step-by-step explanation:
As we know there are 52 cards in total from 2 to 10, and King, Queen, Jack, and Ace, with each of them are equal in numbers which is 4.
Total Number of Kings in the Deck of Cards = 4
P(King) = Number of Kings/Total Number of Cards
= 4/52 = 1/13
