Answer:
The offices can be filled in 4080 ways.
Step-by-step explanation:
This question can simply be solved by permutations.
For the first office there are 17 people available, for the second office 16 people are available, and for the third office 15 people are available.
17x16x15 = 4080 ways.
It can be also thought in a simpler way by thinking that we are to make a combination of 3 people from 17 people and those 3 people can further be ordered into 3! ways. So the number of ways are:
3! x 17C3 = 17P3 = 4080 ways

No

Answer:
The interval where the product will at least break even is given by x ≥ 10.
In interval notation the interval will be denoted by [10, ∞).
Step-by-step explanation:
i) the cost to produce x units of wire is C = 55x + 450
ii) the Revenue is R = 80x
iii) therefore the product will at least break even when
the cost, C = the Revenue, R.
therefore 55x + 450 = 80x 
(80 - 35)x = 45x = 450 ∴x = 450 / 45 = 10.
iv) The interval where the product will at least break even is given by x ≥
10.
In interval notation the interval will be denoted by [10, ∞).
Answer:
Hard to calculate first one is -1/2
Next one is 2.5/1.5 or 2 its hard to tell because of line (not clear)
Next one is -1/2 I think the numbers are small.
