The balance B, in dollars, of your checking account is a function of t, the number of months since the account was opened. The balance is given by the following formula. B = 1150 + 10ot - 922 (a) Use your calculator to make a graph of B versus t covering the first 15 months. 1600 1600 1400 1400 1200 1200 1000 1000 B B00 B B00 600 600 400 400 200 200 10 12 14 10 12 14 1600 1600 1400 1400 1200 1200 1000 1000 B B B00 800 600 600 400 400 200 200 10 12 14 10 12 14 (b) Calculate dB at t = 2. dt dollars per month (c) Explain what the number you calculated in part (b) means in practical terms. The balance increases V by $ from month 2 to month 3.

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.
