The difference between the coat cost for Delaware vs Fairfield is $0.60
Explanation:
For Delaware: 80 × .0725 = $5.80
80+5.80= $85.80
For Fairfield: 80 × .065 = $5.20
80+5.20=$85.20
85.80-85.20=0.60
Answer:
There are 123,410 ways
Step-by-step explanation:
The number of ways or combinations in which we can select k elements from a group of n elements is given by:
![\frac{n!}{k!(n-k)!}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%21%7D%7Bk%21%28n-k%29%21%7D)
In this case, we can replace n by 43 and k by 4, because we are going to select 4 light bulbs from a batch of 43 light bulbs.
So, the number of combinations is calculated as:
![\frac{43!}{4!(43-4)!}=123,140](https://tex.z-dn.net/?f=%5Cfrac%7B43%21%7D%7B4%21%2843-4%29%21%7D%3D123%2C140)
It means that there 123,410 ways to select 4 light bulbs from a batch of 43 lights bulbs to be tested for defects
