You need 560 mL of a 45% alcohol solution. On hand, you have a 20% alcohol mixture. How much of the 20% alcohol mixture and pure alcohol will you need to obtain the desired solution? You will need _______mL of the 20% solution and _______mL of pure alcohol.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
You need 560 mL of a 45% alcohol solution. On hand, you have a 20% alcohol mixture. How much of the 20% alcohol mixture and pure alcohol will you need to obtain the desired solution?
You will need
_______mL of the 20% solution
and
_______mL of pure alcohol.
Let m be the amount in mL you need of the 20% mixture.
The amount of alcohol in the mixture is 0.20mL.
Let a be the amount in mL you need of the pure alcohol.
We need 560mL all together, so a+m=560.
