6. A $90,000 trust is to be invested in bonds paying 6%, CDs paying 5%, and mortgages paying 8%. The sum of the bond and CD investment must equal the mortgage investment. a) If the first-year interest is $5970, write a system of equations whose solution is the amount of each investment and label your variables. b) Find the amount of each investment.
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.
