Using R, please help solve this problem
Homework Answers
library(MASS)
head(Cars93)
a) table(Cars93$Passengers)
b) prop.table(table(Cars93$Passengers))
c)counts <- table(Cars93$Passengers)
barplot(counts, main="passenger Distribution",
xlab="Number of
passengers")
Actually legend can be added only if there are more than one category in bar plot like subdivided bar plot.
you can use extra legend=() in your barplot command. ex legend("topright", c("London","New York","Singapore","Mumbai")
d) pie(counts,legend("topright", c("2","4","5","6","7","8"))

need help please
2) a) Solve the IVP using either variation of parameters or integration factor. Clearly indicate what the varying parameter is if you use variation of parameters or what the integration factor is if you use that method. Also, indicate the general solution to the homogeneous equation. dy 1 dt sin(t) – y, y(0) = 2 b) Draw the direction field and draw in the graph of the particular solution that you found.

Solve the problem. 7) Each day the commuter train transports x passengers to or from the city at $1.75/passenger. The daily fixed cost for running the train is $1200. Write an equation that relates the daily profit, P, in dollars to the number of passengers each day. Then use the equation to find the daily profit when the train has 920 passengers in a day. 7) 8) Each month a beauty salon gives x manicures for $12.00/manicure. The cost to...
