Answer:
2.2 grams
Step-by-step explanation:
We can use the compound decay formula shown below to solve this:
Where
F is the final amount (what we want to find)
P is the present amount (490 grams)
r is the rate of decay, in decimal (28.6% = 28.6/100 = 0.286)
t is the time in minutes (16)
Substituting, we get:
So, after 16 minutes, 2.2355 grams will be remaining.
<em>Rounded to nearest tenth of a gram (1 decimal place) = </em><em>2.2 grams remaining</em>
Try 6.5x10^4
Pretty sure that’s it, If not I’m sorry!
Answer:
y=-2x+2
Step-by-step explanation:
y-y1=m(x-x1)
y-4=-2(x-(-1))
y-4=-2(x+1)
y-4=-2x-2
y=-2x-2+4
y=-2x+2
Answer:
5.5
Step-by-step explanation:
2,3,3,4,5,7,8,8,8,10,10,12
The mean of this data is 7.5. So what you are trying to figure out is the mean between 2 and 7. Since that is 3 and 4 it would be 3.5. So 3.5 is the Q1. Now you have to figure out the mean between 8 and 12. That is 9. This is Q3. You have to subtract 9-3.5 and that is the interquartile range. So 5.5 is the answer. I hope that made sense.
