Answer:
Step-by-step explanation:
14 = 1000 
.014 = 
ln(.014) = k ln(e)
k = -4.268
~~~~~~~~~~~~~~~~~~
after 3 hrs
1000 
0.00274
~~~~~~~~~~~~~~~
4 = 1000 
.004 =
ln(.004)/-4.268 = t
t = 1.29368 hrs

32
Step-by-step explanation:
Subtract 50 - 20 = 32 Sorry not good with math
Answer:
(4, 3)
Step-by-step explanation:
Since the x is by itself in the first equation already, we can solve for y in the next equation and substitute for x.
(y+1)+2y=10
3y+1=10
<u>-1 -1</u>
3y=9
y=3
Next, we need to find x. To do this, we need to substitute y with 3 in one of the equations.
x=(3)+1
x=4
The ordered pair is finally (4, 3).
Hope this helps!! I literally just learned this today...have a great day ❤
Answer:
B.) Probability of 1/6
Step-by-step explanation:
To determine which of the options is least likely to occur, first convert all of them to the same form (fractions, decimals, percentages, etc.). Since 2 are already in fraction form, let's convert the other one to fraction form as well.
0.4 = 4/10
4/10 = 2/5
Now, the probabilities are 2/5, 1/6, and 2/3. Since 1/6 is the smallest number out of the three, that option is correct; a probability of 2/3 the least likely to occur.
