Answer:
0 is the probability that Tim will select a card labeled with a number 6.
Step-by-step explanation:
We are given the following in the question:
Number of cards = 4
Cards with labels:
1,3,5,7
Tim will select one card from the box. We have to find the probability that Tim will select a card labeled with a number 6.
Formula:
0 is the probability that Tim will select a card labeled with a number 6. Thus, it is an impossible event.
So, Jerome bought a total of 80 cards (8x10) out of which he gave out 30 cards (3x10) so he has 50 cards left. (80-30)
The answer would be the first one, 2s+6.
Answer: 4 years
Step-by-step explanation:
A(0) has to be amount at start. Assume that's 5mg
Then A(t) = 5×(0.5)^(0.25t) = 5×2^(-t/4),
(also known as 5 exp(-λ t) with λ = ln(2)/4, incidentally).
We need to such that A(t) = 2.5mg, or 2^(-t/4) is 1/2, which happens when -t/4 is -1, or t is 4.
