The 3 is a positive integer and the 7 is a negative integer so you would do "KFC" also known as (Keep, Flip, and Change)
3
("Keep" the 3 positive)
-
("Flip"the minus sign into a plus sign)
-7
("Change" the negative sign into a positive sign)
So therefore, you would have:
3 + 7, which equals 10
Answer:
Step-by-step explanation:
STEP
1
:
Equation at the end of step 1
(((2 • (x3)) - 3x2) - 23x) + 12
STEP
2
:
Equation at the end of step
2
:
((2x3 - 3x2) - 23x) + 12
STEP
3
:
Checking for a perfect cube
3.1 2x3-3x2-23x+12 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 2x3-3x2-23x+12
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -23x+12
Group 2: 2x3-3x2
Pull out from each group separately :
Group 1: (-23x+12) • (1) = (23x-12) • (-1)
Group 2: (2x-3) • (x2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.

Answer:
or 50.4%
Step-by-step explanation:
The <em>probabilities</em> constitute a branch of mathematics that deals with measuring or quantitatively determining the possibility that an event or experiment produces a certain result. The probability is based on the study of combinatorics and is the necessary foundation of statistics.
A <em>permutation</em> is an ordered arrangement of objects in a group, without repetitions.
A 4-digit PIN is selected. What is the probability that there are no repeated digits?
First, there are only 10 possible values for each digit of the PIN (0, 1, 2, 3, 4, 5, 6, 7, 8, 9). The total possibles 4 PINs are 
There's no repeated numbers and all the four numbers have to be different, which means we have to select 4 numbers out of 10 numbers. Using the permutation equation 
So, the probability that there are no repeated digits is:
P(A)=favorable cases/possible cases
or 50.4%
.
