Answer:
11.57
Step-by-step explanation:
We have a simple formula to solve this:

where
SS is sum of squares
s^2 is the variance, and
n is the number of data points
We are given all the info to find out s^2. Hence,

Answer:
107.14 ml of 70% dextrose and 392.86 ml of sterile water should be used.
Step-by-step explanation:
Since a label prints in the pediatric pharmacy satellite for 500 mL of dextrose 15% solution, but this concentration is not available commercially and needs to be compounded, and available in your pharmacy, you have a 1 L bag of sterile water and a 1 L bag of dextrose 70% available to compound the solution, to determine how many mLs of each are needed to make the requested solution, the following calculation must be performed:
500 x 0.15 = 75
100 x 0.70 = 70
A x 0.70 = 75
A = 75 / 0.70
A = 107.14
Therefore, 107.14 ml of 70% dextrose and 392.86 ml of sterile water should be used.
Answer:

Step-by-step explanation:
6 + 12 + 24 + 48 + 96 =
= 6 + 6 * 2 + 6 * 4 + 6 * 8 + 6 * 16
= 6 + 6 * 2^2 + 6 * 2^2 + 6 * 2^3 + 6 * 2 * 4
= 6 * 2^(n - 1)

Timeperday=time/day=1095/365=3/1=3
answer is 3 hours per day
