Good luck!

You should find the test very familiar if you study the review questions.

# Week of September 10, 2018

This week after the test, we’ll start our work on solving equations. The first batch won’t look much different than last year’s, but we’ll add complexity in the coming weeks. Keep your pencils sharp!

# Join Repl.it

You’ll need to join my repl.it classroom for the next few class sessions. You may use this tool the rest of your lives… It’s extremely handy and allows you to run code in most programming languages and even build web pages for testing!

To join, click me! If you already have an account, just sign in. If you don’t have an account, I STRONGLY suggest using Google log in and using your @dallasisd.org Gmail account. That way, you can’t forget your password! If you want to keep your account after you leave Dallas ISD, you can always add a username and password or change your email address later.

# Day 3 Program

Today we wrote our Nspire version of a dice roll simulation. Here’s an example of the function that simulated 1 or more trials of 6 dice.

Define dice(trials)= Func Local i,roll,counts,total_rolls total_rolls:=6*trials counts:={0,0,0,0,0,0} For i,1,total_rolls roll:=randInt(1,6) counts[roll]:=counts[roll]+1 EndFor Return counts EndFunc

And here’s the program that ran multiple trials to determine the experimental probability of rollling 1,2,3,4,5,6 each the same number of times.

Define rollsim(trials,c)= Prgm Local i,counter,roll counter:=0 For i,1,trials roll:=dice(c) If roll={1,1,1,1,1,1}*c Then counter:=counter+1 EndIf EndFor Disp "all the same: "&string(counter) Disp "EP:"&string(((counter)/(trials))*100.)&"%" Return ((counter)/(trials))*1. EndPrgm

# Day 2 Program â€” Guess!

Here’s at least one way to make the program from class. I’ve added some spaces to make it more readable, but they’re NOT required on the calculators.

Define guess()= Prgm Local num, trial, guessed, guesses guesses:=0 guessed:=false num:=randInt(1,10) Disp num While not guessed Request "Guess (1-10)?",trial,0 guesses:=guesses+1 If trial=num Then guessed:=true ElseIf trial<num Then Disp "Too low!" ElseIf trial>num Then Disp "Too high!" EndIf EndWhile local prt prt := string(guesses) Disp "You got it in" & prt & " guesses." EndPrgm
