Answer:
4.5 mL
Step-by-step explanation:
Amount of Acetaminophen prescribed is 15 mg/kg. This means for every 1 kg of the child's weight, 15 mg of Acetaminophen will be administered to the child.
Weight of the child = 9.6 kg
Since, for each 1 kg the amount of Acetaminophen is 15 mg, the amount of Acetaminophen needed for 9.6 kg will be = 9.6 x 15 = 144 mg
Therefore, the child must be administered 144 mg of Acetaminophen in total.
The strength of Acetaminophen is 160mg / 5 mL. This means 5 mL of an injection contains 160 mg of Acetaminophen. But since, the child needs 144 mg, we need to calculate in mL, the volume of injection needed for 144 mg of Acetaminophen.
160 mg of Acetaminophen is present in an injection of volume = 5mL
1 mg of Acetaminophen is present in an injection of volume = mL
144 mg of Acetaminophen is present in an injection of volume = mL
Thus, 4.5 mL of the injection will contain 144mg of Acetaminophen which would be administered to the patient.

Answer:
Mean = 75
Median = 73.5
Mode = 95
Range = 36
Step-by-step explanation:
Given:
- 77,60,59,70,89,95
Sort:
- 59,60,70,77,89,95
To find:
- Mean
- Median
- Mode
- Range
Mean:
Sum of all data divides by amount.
Therefore, mean = 75
Median:
If it’s exact middle then that’s the median. However, if two data or values happen to be in <em>middle</em>:
From 59,60,70,77,89,95, since 70 and 77 are in middle:
Therefore, median = 73.5
Mode:
The highest value or/and the highest amount of data. Mode can have more than one.
From sorted data, there are no repetitive data nor same data. Consider the highest value:
Therefore, mode = 95
Range:
or highest value - lowest value
Thus:
Therefore, range = 36

The first goal with equations like these is to get one of the variables to go away. You can do that by adding/subtracting one equation from the other. Then you solve for the one variable. Then you plug that answer into one of the original equations and solve.
