Answer:
7 to 3 is this answer
Step-by-step explanation:
if you noticed, with all the other ones they all have 3 : 7 in it. So by the process of elimination it's 7 to 3 that is different. I'll tell you why,
3 : 7, that is the ratio we have as an example. That's why it isn't the different one.
3 to 7, you say 3 : 7 as 3 to 7 to it still has the same ratio
3/7, this is how to type the fraction version of the ratio so it makes sense that it is the same one as 3 : 7.
7 to 3, if you haven't noticed yet, all of them has 3 : 7 as a counterpart. They are all the same but this one, this is 7 : 3 or 7 to 3. So with logic, this is the different ratio.
Answer:
468,000 different codes
Step-by-step explanation:
The code has first 2 letters and then 3 numbers.
The first letter has 26 possibilities to be filled.
The second letter has 25 possibilities, as one letter is already used.
Then, for the numbers, we have:
The first number has 10 possibilities to be filled.
The second number has 9 possibilities to be filled (one used).
The third number has 8 possibilities to be filled (two used).
So, the total number of different codes is:
26*25*10*9*8 = 468,000 different codes.
