Both mean and median are 3.

the mean is calculated by adding the values up and dividing by the number of values. the median is calculated by ordering them from least to greatest and finding the middle value (sometimes there are two).

Hope I helped.

How much pure acid is in 440 milliliters of a 19% solution
ArbitrLikvidat [17]

Answer:

83.6 mL

Step-by-step explanation:

Given 440 mL of 19% acid solution. This means the whole volume of this acid solution is 100%. Let x mL be the volume of pure acid in this solution.

Then

440\ mL - 100\%\\ \\x\ mL - 19\%

Write a proportion:

\dfrac{440}{x}=\dfrac{100}{19}

Cross multiply:

100\cdot x=440\cdot 19\\ \\x=\dfrac{440\cdot 19}{100}\\ \\x=\dfrac{8,360}{100}\\ \\x=83.60\ mL
