To obtain three random three-digit integers
1000 1.(Ran#) = 459
= 48
= 117
(Results shown here are for illustrative purposes only. Actual results will differ.)
To generate random integers in the range of 1 to 6
S.(RanInt) 1 1)(,) 6 )= 2
= 6
= 1
(Results shown here are for illustrative purposes only. Actual results will differ.)
To determine the number of permutations and combinations
possible when selecting four people from a group of 10
Permutations: 10 1*( n P r ) 4 = 5040
Combinations: 10 1/( n C r ) 4 = 210
To perform the following calculations when Fix 3 is selected for the
number of display digits: 10 ÷ 3 × 3 and Rnd(10 ÷ 3) × 3 b
1N(SETUP) 6(Fix) 3 10 / 3 * 3 = 10.000
10(Rnd) 10 / 3 )* 3 = 9.999
Statistical Calculations (STAT)
To start a statistical calculation, perform the key operation N2(STAT)
to enter the STAT Mode and then use the screen that appears to select the
type of calculation you want to perform.
To select this type of statistical calculation:
(Regression formula shown in parentheses)
Press this key:
Single-variable (X)
1(1-VAR)
Paired-variable (X, Y), linear regression (
y = A + B x )
2(A+BX)
Paired-variable (X, Y), quadratic regression
(
y = A + B x + C x
2
)
3( _+CX
2
)
Paired-variable (X, Y), logarithmic regression
(
y = A + Bln x )
4(ln X)
Paired-variable (X, Y),
e exponential regression
(
y = A e
B
x
)
5(
e ^X)
Paired-variable (X, Y),
ab exponential regression
(
y = AB
x
)
6(A
• B^X)
Paired-variable (X, Y), power regression ( y = A x
B
)
7(A
• X^B)
Paired-variable (X, Y), inverse regression
(
y = A + B/ x )
8(1/X)
Pressing any of the above keys ( 1 to 8) displays the Stat Editor.
Note: When you want to change the calculation type after entering the
STAT Mode, perform the key operation 11(STAT) 1(Type) to display
the calculation type selection screen.
