We divide 40 by 1/2:-
40 / 1/2 = 40 * 2/1 = 80 answer
Answer:
1/50* 1/2 =0 .01
Step-by-step explanation:
First, the probability that the spinner lands on 20 is
1
/50
, as 20 is one of the 50 numbers on the wheel, and each number has an equal probability of being selected.
Second, the probability that the spinner lands on an odd number is
1/2
. This is because of the 50 numbers on the wheel, half are even and half are odd.
Answer:
14/16
Step-by-step explanation:
If you multiply 8 by 2 you get 16 so multiply 7 by 2 and you get 14/16
At death means x= 0, so on the graph you can see that (0, 500), so 500 carbon atoms are present at death.
Plug 11,240 in for t in the equation, and you are left with N(t) = 500(1/2)^2 = 125 carbon atoms.
See the graph point (25,000, 24.298)? That means that after 25,000 years 24.298 carbon atoms will be present. So the answer is 25,000 years.
I think the answer is
x < (2b -8) / 3
or
x < 2b/3 - 8/3
