Ok so
for a thing that is P amount at first, with a half life of k days
after t days, the amount left is A
the equation is
given
13% of P remained=A
t=400
replace A with 0.13P and t with 400
0.13P=
divide both sides by P
take the ln of both sides
multiply both sides by k
divide oth sides by ln0.13
k=
evaluate
k=135.897 days
the half life is 135.897 days
3/4 box = 12 oz
we first need to find 1/4 of a box. to do that divide both sides by 3
1/4 box = 4 oz
for a full box which is 4/4 multiply both sides by 4
1/4 x (4) = 4 x (4) oz
4/4 ( or one whole) = 16 oz
Answer:
C - 1
Step-by-step explanation:
The mean is the sum total of all the given value within the data set divided by the number of values in the data set. By counting, you can find that we have 6 values in our data set.
First thing you need to do is add all the numbers given together in order to get the sum of the values in the given data set. Follow these steps presented below:
-2 + 9 - 10 + 3 + 5 + 1
7 - 10 + 3 + 5 + 1
- 3 + 3 + 5 + 1
0 + 5 + 1
5 + 1
6
Now, in order to find the mean, take the sum (6) and divide by the amount of numbers there are; 6.
6/6 = 1
Therefore, the mean is 1.
Hope this helps!
