Answer:
number of possible combinations = 676000
Explanation:
We have:
26 possible letters (a to z)
10 possible digits(0 to 9)
2 letters followed by 3 digits
For letters, since repetition is allowed, therefore, each of the two letters can be any of the possible 26 alphabetical letters (a to z)
For digits, since repetition is allowed, therefore, each digit of the three can be any of the possible 10 digits (0 to 9)
Therefore:
number of combinations = letter * letter * digit * digit * digit
number of combinations = 26 * 26 * 10 * 10 * 10
number of possible combinations = 676000
Hope this helps :)
use this equation to solve for the surface area.
A=2(w+l+hl +hw)
w stands for width
l stands for length
h stands for height
The percentage of that is 20%
The sample mean is μ=105, and sample standard deviation is σₓ=
