Step-by-step explanation:
106
The tens place is the 0, so we look at the ones place
Since 6 is 5 or greater we round the tens place up
0 will round to 1, and the ones places goes to 0
106 rounds to 110
We need a number less than 180 that will round up to 180 from the tens place
We look at the tens place, it has to be less than 8 by 1
17 x
The number must be 5 or greater to round the 7 up to 8
175, 176, 177, 178, 179 will work
We need a number greater than 180 that will round down to 180 from the tens place
We look at the tens place, it has to be equal to 8
18 x
The number must be 4 or less to leave the 8 alone
180, 181, 182, 183, 184
A. We are given that the combination is 1 letter and 8
digits, so the total number of unique combinations would be the product of each
possibilities.
Total unique ID’s = 26 * 10 * 10 * 10 * 10 * 10 * 10 * 10
* 10
or can also be written as
Total unique ID’s = 26 * 10^8
Solving:
Total unique ID’s = 2.6 x 10^9
B. Let us now calculate the total unique ID’s if there is
only 1 letter followed by 3 digits.
Total unique ID’s = 26 * 10^3
Total unique ID’s = 26,000
Since there are 48,000 students and only 26,000 unique ID’s,
therefore it is not enough.
