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!

# 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```
