Answer:
<em>The shortest possible length for the service road is 2.88 miles.</em>
Step-by-step explanation:
According to the below diagram, 
and 
are the positions of airport, shopping center and factory respectively.
Given that, 
and 
In right triangle 
The shortest possible length for the service road from the shopping center to the highway that connects the airport and factory is 
.
That means, 
is also a right triangle in which 
, Hypotenuse
miles and is the opposite side in respect of 
or 
.
Now in right triangle 
So, the shortest possible length for the service road is 2.88 miles.
You started out as if it was going to be a probability problem, but it turned out to be a simple binary counting problem.
It really doesn't matter how many of each color are in the bag, or how many marbles there are in the bag all together. I think you're just asking how many ways there are to pull out two white ones and two black ones. That's exactly the same question as "How many 4-bit binary numbers can be written with two 1's and two 0's ?"
It's easy to draw up that list. You start out like this:
0011, 0101, 1001, 0110, 1010, 1100 .
Gosh. I just wanted to start out doing the list, but I think that's all of them.
There are six (6) ways.
WWBB, WBWB, BWWB, WBBW, BWBW, and BBWW .
Answer:
Step-by-step explanation:
- 4 + 4 = 0
- 9 + 8 = - 1
8 + (-1) = 7
-6 + (-2) = - 8
What is the sum of negative 9 and 7 = > - 9 + (-7) = - 9 - 7 = - 16
