Answer:
We have 197 g of Co-60 after 18 months.
Step-by-step explanation:
We can use the decay equation.
Where:
- M(f) and M(i) are the final and initial mass respectively
- λ is the decay constant (ln(2)/t(1/2))
- t(1/2) is the half-life of Co
- t is the time at the final amount of m
<u>Therefore, we have 197 g of Co-60 after 18 months.</u>
I hope it helps you!
<span>y=-2/4x +2
slope = -2/4 = -1/4
</span><span>parallel so it has same slope = -1/2
passing thru (6,3)
y = mx+b
3 = -1/2(6) + b
b = 3 +3
b = 6
equation
y = -1/2x + 6</span>
Answer:
4*y^2 - 12*y
Step-by-step explanation:
4y(y-3) = 4y*y - 4y*3 = 4*(y^2) - 12*y
I would use the theoretical method because each of the 52 cards is equally likely to be drawn.
There are 52 cards in a deck so there are 52 possible outcomes.
The event of interest is drawing a club or a diamond. There are 13 clubs and 13 diamonds. Add those up and that gives you 26 cards, which is the possible number of outcomes. knowing this we divide 26 by 52.
number of outcomes / total number of possible outcomes
26 / 52 = 1 / 2 = .5 = 50%
So the probability of this even is 1 out of 2 or you have a 50% chance of getting your club or diamond
