Answer:
C.4.18g
The amount will remain after 12 days is 4.18 g
Step-by-step explanation:
we can use formula
where
h is half life time
t is time in days
Po is initial quantity
P(t) is the quantity after t days
we are given
Curium-243 has a half-life of 28.5 days
In a sample of 5.6 grams of curium-243
so,
now, we can plug values
now, we can plug t=12
So,
The amount will remain after 12 days is 4.18 g
Answer:
Decreasing value
Step-by-step explanation:
Answer:
0.8
Step-by-step explanation:
We see that there are 5 equal sections, 4 of which have beavers on them.
P(beaver) basically means that we want to find the probability of landing on a beaver; in other words, we're looking for a fraction:
(# sections you can land on a beaver) / (total # of sections)
Here, the number of sections you can land on a beaver is 4, while the total number of sections is 5. So, P(beaver) = 4/5.
Thus, the answer is 4/5, which can be written as the decimal 0.8.
Hope this helps!
