1/8 is rational because irrational numbers can be written as decimals but not fractions
Hello,
Let's place the last digit: it must be 2 or 4 or 8 (3 possibilities)
It remainds 4 digits and the number of permutations fo 4 numbers is 4!=4*3*2*1=24
Thus there are 3*24=72 possibilities.
Answer A
If you do'nt believe run this programm
DIM n(5) AS INTEGER, i1 AS INTEGER, i2 AS INTEGER, i3 AS INTEGER, i4 AS INTEGER, i5 AS INTEGER, nb AS LONG, tot AS LONG
tot = 0
n(1) = 1
n(2) = 2
n(3) = 4
n(4) = 7
n(5) = 8
FOR i1 = 1 TO 5
FOR i2 = 1 TO 5
IF i2 <> i1 THEN
FOR i3 = 1 TO 5
IF i3 <> i2 AND i3 <> i1 THEN
FOR i4 = 1 TO 5
IF i4 <> i3 AND i4 <> i2 AND i4 <> i1 THEN
FOR i5 = 1 TO 5
IF i5 <> i4 AND i5 <> i3 AND i5 <> i2 AND i5 <> i1 THEN
nb = ((((n(i1) * 10) + n(i2)) * 10 + n(i3)) * 10 + n(i4)) * 10 + n(i5)
IF nb MOD 2 = 0 THEN
tot = tot + 1
END IF
END IF
NEXT i5
END IF
NEXT i4
END IF
NEXT i3
END IF
NEXT i2
NEXT i1
PRINT "tot="; tot
END
Answer:
or 3
Step-by-step explanation:
To find the slope find two coordinates and set up the equation 
For the coordinates (0,2) and (2,8) y2 is 8 and y1 is 2. x2 is 2 and x1 is 0. 
you have to do subtraction first. 8-2 = 6 and 2-0 = 2
Now we have the equation 
this can be simplified to
Answer:
there is more of a probability to get a constant considering there is about 1/3 of vowels, so player 2 would min most of the time
Step-by-step explanation:
there are 6 vowels and 15 constants, that's about 1/3 of the amount of letters in Gymnastics and Watermelon
Answer:
B.11.4
Step-by-step explanation:
The sum the 3 angles of a triangle add to 180 degrees
5x+8x+2x+9 = 180
15x+9 =180
Subtract 9 from each side
15x+9-9 =180-9
15x = 171
Divide by 15
15x/15 =171/15
x =11.4
