The price of a dress is reduced by 20%. When the dress still does not sell, price was then reduced by 10% of the reduced price.If the price of the dress after both reductions is $264,what was the original price?
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.
2) The price of a dress is reduced by 20%. When the dress still does not sell, price was then reduced by 10%
of the reduced price.If the price of the dress after both reductions is $264,what was the original price?
(3) If a projectile is launched into the air at 29.4 feet per second from a height of 60 feet,
its height (in feet) is given by S(x) = 60 + 29.4x − 9.8x2
, where x is in seconds.
Showing all working, determine:
(a) How long will it take the projectile reach its maximum height?
(b) What is the highest height that the projectile can attain?
