Answer:
210
Step-by-step explanation:
450 X 1/3 = 150
450 X 1/5 = 90
.
90 + 150 = 240
.
450 - 240 = 210
We estimate that 12/480=1/40 fish are tagged, so 600 is 1/40 of the total number of fish. This means that there are about 600*40=24000 fish total in the pond.
Answer:
the monthly rents of the apartments
Step-by-step explanation:
In the field of statistics, the population of interest may be defined as the group or the population from which the experimenter or the researcher tries to make conclusions or draw their results.
In the context, I am interested to study the cost of the rented house that is more than others in the West Campus area.
So I recorded the monthly rents of the apartments from a sample of 30 one bedroom apartments.
Therefore, the population of interest for my study here is the monthly rents recorded from the sample of one bedroom apartments.
Answer:

Step-by-step explanation:
Given that from a well shuffled set of playing cards (52 in number) a card is drawn and without replacing it, next card is drawn.
A - the first card is 4
B - second card is ace
We have to find probability for

P(A) = no of 4s in the deck/total cards = 
After this first drawn if 4 is drawn, we have remaining 51 cards with 4 aces in it
P(B) = no of Aces in 51 cards/51 = 
Hence

(Here we see that A and B are independent once we adjust the number of cards. Also for both we multiply the probabilities)
