So you already have the formula for calculating the dosage for child with: C = a/(a+12)x 180 ml Not sure why you have double brackets
variables are: a = child's age, so everywhere you have an "a" replace it with the age of child.
Example: 5 year old child
C = 5/(5+12)*180= 5/(17)*180 = 5/3060 = .0016 ml or milligrams
2(319) +3(264) = 1430

Answer:
Option (B) is the correct answer to the following question.
Step-by-step explanation:
Step-1: We have to find the Mean of the series.
The series is Given in the question 62 61 61 57 61 54 59 58 59 69 60 67.

Step-2: We have to find the Standard Deviation.
Let Standard Deviation be x.
Formula of Standard Deviation is: 
Put value in formula of Standard Deviation,
= 40.75
Step-3: Then, we have to find the critical value by chi-square.


Then, find the confidence interval which is 95%.


Answer:
There are 6 adults. <em>My mistake! I had the wrong equation. 3 + 9a = 57.</em>
Step-by-step explanation:
- <u>There is only 1 child in the group.</u>
- Cost for children is 3$.
- <u>The cost for adults is 9$.</u>
