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:
The given equation cannot be written in slope intercept form
Step-by-step explanation:
we know that
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Is the equation of the line in slope intercept form
where
m is the slope
b is the y-intercept
In this problem we have
![x=9.4](https://tex.z-dn.net/?f=x%3D9.4)
This is a vertical line (parallel to the y-axis)
The slope is undefined
therefore
The given equation cannot be written in slope intercept form
The answer it that the net was changed but the market was also turn dia time Tito a
Answer:
45000
Step-by-step explanation:
put the equation like this
1000
x 45
And multiple form right to left or just take 45 and add 3 0's because anything multiplied by 1 is what number u multiplied it by
