Answer:
It's x = -1.5
Step-by-step explanation:
To figure out the total amount of hours an employee works, we have to multiply the total amount of employees by the amount of hours each employee would work.
To simplify the mixed fraction of hours they work, convert the mixed fraction into an improper fraction:

Multiply the whole number by the denominator:

Add this number to the numerator to convert the mixed fraction into an improper fraction:


Now we can multiply the two numbers together (note that a whole number can be treated as the number above the denominator 1):
5 employees working 94/15 hours a day:

To simplify this fraction, divide the numerator by the denominator:

The whole number stays as a number, and the remainder is the new numerator:

The fraction can be further simplified by dividing both the numerator and denominator by the greatest common factor:
Factors of 5: {1,
5}
Factors of 15: {1,3,
5,15}


The 5 employees will work a total of
31 and 1/3 hours a day.

Answer:
x=-39
Step-by-step explanation:
Since in a pass code, the placement of the digits is
important, therefore this means that to solve for the total number of
possibilities we have to make use of the principle of Permutation. The formula
for calculating the total number of possibilities using Permutation is given
as:
P = n! / (n – r)!
where,
n = is the total amount of numbers to choose from = 20
r = is the total number of digits needed in the passcode =
4
Therefore solving for the total possibilities P:
P = 20! / (20 – 4)!
P = 20! / 16!
P = 116,280
<span>Hence there are a total of 116,280 possibilities of pass
codes.</span>
