Answer:
Step-by-step explanation:
From the given information,
Suppose
X represents the Desktop computer
Y represents the DVD Player
Z represents the Two Cars
Given that:
n(X)=275
n(Y)=455
n(Z)=405
n(XUY)=145
n(YUZ)=195
n(XUZ)=110
n((XUYUZ))=265
n(X ∩ Y ∩ Z) = 1000-265
n(X ∩ Y ∩ Z) = 735
n(X ∪ Y) = n(X)+n(Y)−n(X ∩ Y)
145 = 275+455 - n(X ∩ Y)
n(X ∩ Y) = 585
n(Y ∪ Z) = n(Y) + n(Z) − n(Y ∩ Z)
195 = 455+405-n(Y ∩ Z)
n(Y ∩ Z) = 665
n(X ∪ Z) = n(X) + n(Z) − n(X ∩ Z)
110 = 275+405-n(X ∩ Z)
n(X ∩ Z) = 570
a. n(X ∪ Y ∪ Z) = n(X) + n(Y) + n(Z) − n(X ∩ Y) − n(Y ∩ Z) − n(X ∩ Z) + n(X ∩ Y ∩ Z)
n(X ∪ Y ∪ Z) = 275+455+405-585-665-570+735
n(X ∪ Y ∪ Z) = 50
c. n(X ∪ Y ∪ C') = n(X ∪ Y)-n(X ∪ Y ∪ Z)
n(X ∪ Y ∪ C') = 145-50
n(X ∪ Y ∪ C') = 95
I think it is 0
6= 1-2(0)+5
6=1-0+5
6=1+5
6=6
You should check just in case.
Answer:
-12x = y^2
Step-by-step explanation:
Notice that the vertex and the focus are both located on the horizontal line y = 0 (that is, on the x-axis).
Because the focus is to the left of the vertex, we know that the parabola opens left.
The distance between focus and vertex is 3 units.
We'll adapt this equation: 4px = y^2. Here p is -3:
4(-3)x = y^2, or
-12x = y^2
Answer:
The Giraffe has a weight which is 3 times that of the Gorilla
Step-by-step explanation:
Here, we are interested in calculating the number of ways in which the giraffe’s weight is greater than the gorillas
From the question, the weight of the giraffe is 4.5 * 10^3 pounds
The weight of the Gorilla is 150 pounds
So, the number of ways it will be greater will be;
(4.5 * 10^3)/150 = 4500/150 = 30 times
The Giraffe is 3 times the weight of the Gorilla
111.
660/6 = 110. In order to make a profit you need to sell at least one more than that.
Hope this helps.
