Answer:
4 dollars
7 dimes or $4.70.
Step-by-step explanation:
The 4 dollars, 12 dimes, and 10 pennies added up together is $5.30. You will subtract that from $10.00 and you will get $4.70. That will be 4 dollars and 7 dimes left that is needed, or $4.70.
(arrange the data set from least to greatest)
0, 0, 2, 2, 3, 4, 6, 8
(find the median: *the middle number*)
Median: 2.5
Lower quartile: 1
Upper quartile: 5
Interquartile range : upper quartile - lower quartile = answer
Interquartile range: 5 - 1 = 4
So the IQR or interquartile for the following data set is 4.
Answer:
(a)8.0mg
(b)36.87 hours
(c)-0.168
Step-by-step explanation:
The amount of Valium in that person's bloodstream at any time can be modeled with the exponential decay function 
(t in hours)
(a)After 12 Hours
(b)If A(t)=5mg
Then:
(c)
To add the two expressions, we can write it as:
4.6x-3 + (-5.3x+9)
We can distribute the plus sign (which means just drop the parenthesis in this case):
4.6x-3-5.3x+9
Now, we can simplify by combining like terms:
-0.7x+6
