Answer:
0.28
Step-by-step explanation:
To know the probability we first need to know the total number of choices for each character in the license plate. Since there are a total of 10 possible numbers (0-9) and 26 letters in the English Alphabet. Then this means that each character has a total of 36 possible choices. Out of these 36 only 10 are numbers, therefore the probability of the first character being a number is
or 0.2777
If we rounded the decimal to the nearest hundredth it would be 0.28
Answer:
8
Step-by-step explanation:
Hi,
When we divide 5655 by N, we get remainder of 11, which means that 5655-11 is a multiple of N.
5655 - 11 = 5644 is a multiple of N.
Similarly, 5879-14 should be a multiple of N.
5879 - 14 = 5865 is a multiple of N.
Because 5644 and 5865 are both multiples of N, their difference must be a multiple of N.
5865 − 5644 = 221 then 221 is a multiple of N.
We have three number of which N can be a multiple of, however we choose to factorize the smallest possible number amongst these three, which is 221. (This is only for simplification of the solution, smaller the number, less the factors)
221 : 1, 13, 17, 221.
There are only two two - digit factors: 13 and 17.
We divide 5865 and 5644 by both numbers.
Looking at these results, we know only 17 divides all three numbers.
Hence N=17.
The sum of both digits will be: 1 + 7 = 8
Answer:
Option A,
Step-by-step explanation:
<u>Step 1: Determine the numbers that are multiples of 3</u>
8 → Not a multiple of 3
9 → Multiple of 3
14 → Not a multiple of 3
19 → Not a multiple of 3
25 → Not a multiple of 3
34 → Not a multiple of 3
38 → Not a multiple of 3
<u>Step 2: Determine the probability of chosing a multiple of 3</u>
Since we only have 1 number that is a multiple of 3 out of the 7 given numbers, that means that we do the following:
