Answer:
Quincy’s friend has a program that can test 100,000 passwords per second. Given what Quincy’s friend knows about Quincy’s password, how long would it take him to test all the possibilities? How much longer would it take Quincy’s friend to test all the possible passwords if he knew that Quincy’s password was 5 characters long, but did not know whether those characters were letters or digits?

Well, find a common denominator. We have the common denominator to be 6.
So, 3/6 is employees. 2/6 is spouses of employees. So, 1/6 is left, and that is your answer
Answer:
$12,800
Step-by-step explanation:
42-18= 24
24 is the years the money is growing.
24/4=6
200x2x2x2x2x2x2=12,800
if it doubles every six years it would be 200x2x2x2x2=3,200
the difference is 9,600
Yes, parentheses can change the order in which operations are performed in an expression.
Let us understand this with two examples.
First example.
Let us suppose we have to simplify the expression
In this expression we have evaluated subtraction first instead of multiply.
Second example.
Let us suppose we have to simplify the expression
In this expression we have evaluated multiplication first and then subtraction.
Therefore, from above two examples we can see that parentheses can change the order in which operations are performed in an expression.
