Answer:
1,404,000 unique passwords are possible.
Step-by-step explanation:
The order in which the letters and the digits are is important(AB is a different password than BA), which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this question:
2 digits from a set of 10(there are 10 possible digits, 0-9).
3 characters from a set of 26. So
1,404,000 unique passwords are possible.
Answer: 2.5%
3967.50 - 3450 = 517. 50
i = prt/100
i = 517.50, p = 3450, t = 6
517.50 = 3450 x r x 6/ 100
517.50 = 20700r/100
517.50 = 20700r
517.50/20700 = r
r = 0.025 = 2.5%
The range is 31.
To find the range, you subtract the smallest number, in this case 14, from the largest number, in this case 45.
Step-by-step explanation:
The nth term just mean how to work out the next number in he series. In this series of numbers, you have to square three n and add it onto 10 n to do this.
N is the term- the number it comes in the sequence.
Example:
2 3 4 5 6
2= the first terof the sequence
3= second term
4=3rd term
And so on
To work out what the next term is (6th term) you use this expression:
N+1
The first term is 2. As it is the first n=1. 1+1=2 so that works
The seco d term is 3. As it is the second term n=2. 2+1+3 so that works
And so on
This might help
But you have to do the rest
