Answer:
x = 110, y = 153.
Step-by-step explanation:
4x - 3y = -19 Multiply by 2
3x - 2y= 24 Multiply by 3.
8x - 6y = -38
9x - 6y = 72 SUBTRACT
-x = - 110
x = 110
Substitute for x :
3(110) - 2y = 24
2y =330 - 24
2y = 306
y = 153.
6/8 = 3/4 = 0.75
3/4 x 4 = 3
3/6 = 1/2
so, the value is 0.5, or 1/2.
Answer:
144
Step-by-step explanation:
The best way to attempt this question is to solve it using a Venn diagram
From the given information, Let;
D = documentaries
I = interview shows
G = game show reruns
From the images attached below, we will see how the Venn diagrams are being drawn step by step and calculated.
i.e
= 300 - (90 + 60 + 24 + 6 + 12 + 18 + 24)
= 300 - 234
= 66
∴
No of those interested in exactly one kind of show = 66 + 60 + 18
= 144
∴
F(5) would be 16. because f(1) is only 3.2 so if you multiply 3.2 x 5 you will get 16
