The correct answer is: Area of △ABC = 20Explanation:Since the area of △AOD = 10; therefore. the area of <span>△BOC is also 10.
Now:
The area of </span>△ABC = Area of △AOB + Area of <span>△BOC --- (1)
Since Area of </span>△AOB =
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
(Area of <span>△ABC) --- (2)
Plug (2) in (1):
(1) => Area of </span>△ABC =
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
(Area of △ABC) + 10
=>
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
(Area of △ABC) = 10
=> (Area of △ABC) =
20<span>-i

The breaking strengths of cables produced by a certain manufacturer have a standard deviation of pounds. a random sample of newly manufactured cables has a mean breaking strength of pounds are 1821.9.
<h3>
What are the cables?</h3>
The cables are the wires that provide the connection.
- Round your solutions to 1 decimal place pattern imply = 1800 fashionable error = zs = 2.576[85/sqrt(100)] = 0.2576*eighty five = 21.896
- 99% CI: 1800-21.896 < u < 1821.896
- 99% CI: 1778.1 < u < 1821.9.
