In this equation w = -1.1
In order to find this, get all w values to the right side and all numbers to the left side.
-2.27 + 9.1w + 1.3w = -3.4w - 17.45 ----> combine like terms
-2.27 + 10.4w = -3.4w - 17.45 ----> add 3.4w to both sides
-2.27 + 13.8w = -17.45 ----> add 2.27 to both sides
13.8w = -15.18 -----> divide both sides by 13.8
w = -1.1
Solution :
Let A = Economics, B = Mathematics
n(A) = 311, n(B) = 243, ![$n(A \cap B) = 135$](https://tex.z-dn.net/?f=%24n%28A%20%5Ccap%20B%29%20%3D%20135%24)
a). So, ![$n(A \cup B) = n(A) +n(B) - n(A \cap B)$](https://tex.z-dn.net/?f=%24n%28A%20%5Ccup%20B%29%20%3D%20n%28A%29%20%2Bn%28B%29%20-%20n%28A%20%5Ccap%20B%29%24)
= 311 + 243 - 135
= 419
b). n(A only) = 311 - 135
= 176
n(B only) = 243 - 135
= 108
Exactly one of these two courses
![$=\frac{176+108}{500}$](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B176%2B108%7D%7B500%7D%24)
= 0.568
c). Neither economics nor mathematics
![$=\frac{500-419}{500} $](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B500-419%7D%7B500%7D%20%24)
![$=\frac{81}{500}$](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B81%7D%7B500%7D%24)
= 0.162
Answer:
HI HI from the UK,
Step-by-step explanation:
The triangle pay $32 more for that day than it paid per day during the first period of time.
Step-by-step explanation:
The given is,
Triangle Construction pays Square Insurance $5,980
To insure a construction site for 92 days
To extend the insurance beyond the 92 days costs $97 per day
Triangle extends the insurance by 1 day
Step:1
Insurance per day from the 92 days period,
![= \frac{Total insuratio for 92 days}{Period}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7BTotal%20insuratio%20for%2092%20days%7D%7BPeriod%7D)
Where, Total insurance for 92 days = $ 5,980
Period = 92 days
From the values, equation becomes,
![=\frac{5980}{92}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5980%7D%7B92%7D)
= $ 65 per day
Step:2
Insurance per day after the 92 days,
= $ 97
Amount Pay for that day than it paid per day during the first period of time,
![=(97-65)](https://tex.z-dn.net/?f=%3D%2897-65%29)
= $32
Result:
The triangle pay $32 more for that day than it paid per day during the first period of time, if the Triangle Construction pays Square Insurance $5,980
to insure a construction site for 92 days and to extend the insurance beyond the 92 days costs $97 per day.
Answer:
It could either be x * 3.25 or x + 18
Step-by-step explanation:
8 * 3.25 = 26
8 + 18 = 26
