405600. Six possible variations of 2 letters (L) and 2 digits (D): LLDD would be 26 x 26 x 10 x 10 = 67600 LDLD would be 26 X 10 X 26 X 10 = 67600 LDDL would be 26 X 10 X 10 X 26 = 67600 DLDL would be 10 x 26 x 10 x 26 = 67600 DLLD would be 10 x 26 x 26 x 10 = 67600 DDLL would be 10 x 10 x 26 x 16 = 67600 6 x 67600 = 405600
For every letter there are 26 possibilities, for every digit, 10. Multiply all of this together (26 x 26 x 10 x 10 x 10) = 676,000.
-8 + 10x = 18 10x = 18+8 10x = 26 x = 26/10 x = 2.6
x2 = (26 + x)2 Taking square roots: x = +/-(26 + x) Then x = 26 + x or x = -26 -x The first gives a nonsense "equation" 0 = 26 but the second gives 2x = -26 or x = -13
26. for the pattern: add 10, subtract 5, add 10, subtract 5, ...the series is given as x+10-5so here16+10= 26-5=21+10=31-5=26so next no. is 26262626

26 - 10% = 26 x (1 - (10/100)) = 26 x 0.9 = 23.4
The answer depends on where the missing number is meant to be. If 2, 4, 6, 10, 26, X: then X = 72 If 2, 4, 6, 10, X, 26: then X = 16.8 If 2, 4, 6, X, 10, 26: then X = 6.6 If 2, 4, X, 6, 10, 26: then X = 5.4 If 2, X, 4, 6, 10, 26: then X = 1.2 If X, 2, 4, 6, 10, 26: then X = 6
26 x 10 = 260
10 x 40 x 26 is equal to 10,400
It depends where you want the parentheses: 15 + (26 x 10) = 275 (15 + 26) x 10 = 410
This is easiest to answer by working out the probability of not getting such a license plate and subtracting that from 1. There are 10 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 10 different possible license plates (since there are 10 digits: 0-9 and 26 letters: A-Z). To not have any repeated digits or letters, there are: 10 x 26 x 25 x 24 x 23 x 22 x 21 x 20 x 9 possible license plates (since the two digits must be different and the seven letters must all be different). Meaning the probability of getting one of these is: (10 x 26 x 25 x 24 x 23 x 22 x 21 x 20 x 9)/(10 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 10) = (25 x 3 x 23 x 11 x 21 x 9)/(26 x 13 x 13 x 13 x 13 x 13) = 3586275/9653618 ⇒ probability of getting at least one repeating digit or number is: 1 - 3586275/9653618 = 6067343/9653618≈ 0.629
26 x 26 x 26 x 10 x 10 x 10 = 17576000
780 SF Solution: 26 x 30 = 26 x 3 * 10 = 78 x 10 = 780
2.8 x 10= 28 26 x 100= 2600 Therefore 2600>28, 26 x 100 is the greater of the two equations
For every letter there are 26 possibilities, for every digit, 10. Multiply all of this together (26 x 26 x 10 x 10 x 10) = 676,000.
The product of 2.6 x 10 = 26
