Answer:
1. 120 ways
2. 720 ways
Step-by-step explanation:
When the order is important, we have a permutation.
When the order is not important, we have a combination.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
1. If the jobs are all the same.
Same jobs means that the order is not important. So
3 from a set of 10.
120 ways
2. If the jobs are all different.
DIfferent jobs means that the order matters.
720 ways
Answer:
C
Step-by-step explanation:
6(a+b) + 2z = -8 ; divide by 2
3(a+b) + z = -4
a+b+z = 2; subtract z from both sides
a+b = 2-z; substitute a+b into equation 3(a+b) +z = -4
3(2-z) +z = -4; distribute
6 - 3z+ z= -4 ; subtract 6 on both sides
-3z + z = -4 -6 ; combine like terms
-2z = -10; divide both sides by -2
z= 5
3(a+b) +z = -4; substitute z by 5
3(a+b) +5 = -4; subtract 5 from both sides
3( a+b) = -4 -5; combine like terms
3(a+b) = -9; divide both sides by 3
(a+b) = -3
412 is a whole number, 638 is the number you want to look at.
your answer is 412 638/1000
or 412 63.8/100
