Let f be the function that inputs a cost (in dollars) and outputs the cost after applying the "$20 off" coupon, and let g be the function that inputs a cost (in dollars) and outputs the cost after applying the "35% off" coupon. Which of the following correctly represents the fact that the cost of purchasing $400 worth of goods is $240 when the "35% off" coupon is applied first followed by the "$20 off" coupon? g(f(400))=240 f(f−1(400))=240 f(g(240))=400 f(g(400))=240
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.
A store has two different coupons that customers can use. One coupon gives the customer $20 off their purchase, and the other coupon gives the customer 35% off of their purchase. Suppose they let a customer use both coupons and choose which coupon gets applied first. For this context, ignore sales tax.
Let f be the function that inputs a cost (in dollars) and outputs the cost after applying the "$20 off" coupon, and let g be the function that inputs a cost (in dollars) and outputs the cost after applying the "35% off" coupon.
Which of the following correctly represents the fact that the cost of purchasing $400 worth of goods is $240 when the "35% off" coupon is applied first followed by the "$20 off" coupon?
- g(f(400))=240
- f(f−1(400))=240
- f(g(240))=400
- f(g(400))=240
- g(f(240))=400
