0 and 1.
A probability of 0 means that the event will not happen. For example, if the chance of being involved in a road traffic accident was 0 this would mean it would never happen. You would be perfectly safe. A probability of 1 means that the event will happen.
Answer:
The average price of a ticket originating in Chicago using United Airlines is $1212.40.
Step-by-step explanation:
The data provided is as follows:
United Air France British
Chicago 1063 1314 1442
1299 1493 1413
995 1443 1063
1299 1577 1442
1406 1314 1575
London 1015 1374 1603
856 977 1531
802 1043 1079
850 1070 807
935 1428 870
The data for the price of a ticket originating in Chicago using United Airlines is:
Chicago = {1063, 1299, 995, 1299, 1406}
Compute the average price as follows:
![=\frac{1}{5}\times [1063+1299+995+1299+1406]\\\\=\frac{6062}{5}\\\\=1212.40](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B5%7D%5Ctimes%20%5B1063%2B1299%2B995%2B1299%2B1406%5D%5C%5C%5C%5C%3D%5Cfrac%7B6062%7D%7B5%7D%5C%5C%5C%5C%3D1212.40)
Thus, the average price of a ticket originating in Chicago using United Airlines is $1212.40.
Answer:
This is a 45, 45, 90 triangle.
That means, x is equal to 12, since all 45, 45, 90 triangles are also isosceles, meaning that two of their sides are equal to each other.
To solve for y, we can use the Pythagorean theorem:
12^2 + 12^2 = y^2
288 = y^2
y=12

Answer:
- length: 14 feet , width: 43 feet, or
- length: 86 feet, width: 7 feet
Both solutions are valid.
Explanation:
1. First assumption is that the shape of the fence is <u>rectangular</u>.
2. Second, assum the length parallel to the wall measure y feet, so the other two lengths, y, together with x will add up 100 feet
3. The, the area of the fence will be:
- length × width = xy = 600
4. Now you have two equation with two variables which you can solveL
- Solve for y in the first equation: y = 100 - 2x
- Substitute the value of y into the second equation: x (100 - 2x) = 600
5. Solve the last equation by completing squares:
- Distributive property: 100x - 2x² = 600
- Divide both sides by - 1: 2x² - 100x = - 600
- Divide both sides by 2: x² - 50x = -300
- Add the sequare of the half of 50 to both sides: x² - 50x + 625 = 325
- Factor the left side: (x - 25)² = 325
- Square root both sides: x - 25 = ± 18.028
- Clear x: x = 25 ± 18.028
- x = 43.028 ≈ 43 or x = 6.972 ≈ 7
Both values are valid,
If x = 43 , then y = 600/43 = 14
If x = 7, then y = 600/7 = 86
Thus, the lenght and width of the fence may be:
- 43 feet (width) and 14 feet (length), or
- 7 feet (width) and 86 feet (length).
