Answer:
C. 6.736
Step-by-step explanation:
The unmarked angle is 180-80-40 = 60 degrees. Given the angles of the triangle and one side length there is enough information to use the Law of Sines to solve the triangle--eliminating choice D.
The angle opposite x is larger than the angle opposite 5, so <em>x will be larger than 5</em>. That leaves only answer choice C: 6.736.
___
If you want to actually use the law of sines to determine x, you know that ...
x / sin(60°) = 5 / sin(40°)
x = 5·sin(60°)/sin(40°) . . . . . . multiply by sin(60°)
x ≈ 6.736

Answer:</h2><h2>
The expected number of people who will attend this concert = 2260</h2>
Step-by-step explanation:
The concert organizers estimate people will attend if it is not raining = 19000
If its raining people will attend = 4000
On the day of the concert, meteorologists predict a 90% chance of rain.
This means 10 % chance of not raining
The expected number of people = 90% (4000) + 10% (19000)
= 360 + 1900
= 2260
The expected number of people who will attend this concert = 2260
