An article in the $J,$ rnal of Database Management "Experimental Study of a Self$-$Tuning Algorithm for DBMS Buffer Pools," $(2005,$ Vol. $16,$ pp$.1-20)$ provicted the workload used in the TPC$-$C OLTP $($Transaction Processing Performance Council's Version C On$-$Line Transaction Processing$)$ benchmark, which simulates a typical order entry application.

Average frequencies and operations in TPC$-$C

$\backslash$table$[[$Transaction$,$Frequency,Selects,Updates,Inserts,Deles,,$],[$New order,$43,23,11,12,0,0,0],[$Payment$,44,4\mathrm{.}2,3,1,0,0\mathrm{.}6,0],[$Order Status,$4,11\mathrm{.}4,0,0,0,0\mathrm{.}6,0],[$Delivery$,5,130,120,0,10,0,0],[$Stock Level,$4,0,0,0,0,0,1]]$

The frequency of each type of transaction $($in the second column$)$ can be used as the percentage of each type of transaction. Let $x$ and $Y$ denote the average number of selects and updates operations, respectively, required for each type transaction. Determine the following. Round your answers to two decimal places $($e$.$g$.98\mathrm{.}76).$
