Answer:
The list of event (pulling a face card,F or a number card, N) that correctly makes up the sample space when a card is drawn without replacement is;
FF
FN
NF and
NN
Step-by-step explanation:
Here we have the definition of a sample space as one which has all possible outcomes
Therefore, the list of events that correctly makes up the sample space of events when you pull out two cards we have either a face card F or a number card N, and the sample space is;
FF
FN
NF and
NN
Where the likelihood of each outcome changes as the number of face cards and number card changes as each card is drawn without replacement.
Answer: The answer to the equation 4,240/8 = 530
Step-by-step explanation:
4,240 divided by 8 = 530
4,000 divided by 8 = 500
4,800 divided by 8 = 600
(For part B 500 would be an underestimate of the answer to 4,240/8 and 600 would be an overestimate of 4,240/8)
1 litre = 1000 millilitres so 1200-200= 1000 millilitres left or 1 litre left
Answer: Pupulation = A*0.95^t
where t is the numer of hours that has passed, and A is the initial population of the bacteria.
Step-by-step explanation:
If the initial population of bacteria is A.
After one hour we can see that the population has decreaesed by 5%, so the new population is
P = A - 0.5*A = 0.95*A
After other our, the population decreased by 5% again, the new population is:
P = (0.95*A) - 0.5*(0.95*A) = 0.95*0.95*A = A*0.95^2
And so on.
This is an exponential decay, so we can write this relation as:
Pupulation = A*0.95^t
where t is the numer of hours that has passed, and A is the initial population of the bacteria.
