Answer:
Q. Find the range and coefficient of range of the data :
- 100 , 200 , 400 , 600 , 900
⇾ Solution :
- largest value ( L ) = 900 & smallest value ( S ) = 100
We know , Range is the difference between the largest and smallest value. By definition ,
1. Range = Largest value - Lowest value = 900 - 100 =
2. Coefficient of range =
Q. If f ( x ) = 9x - 8x and x belong to { 0 , 4 , 3 ,5 }. Find the range.
⇾ Solution:
When x = 0 , f ( 0 ) = 9 × 0 - 8 × 0 = 0
When x = 4 , f ( 4 ) = 9 × 4 - 8× 4 = 4
When x = 3 , f ( 3 ) = 9 × 3 - 8 × 3 = 3
When x = 5 , f ( 5 ) = 9 × 5 - 8 × 5 = 5
- Range = { 0 , 4 , 3 , 5 )

To do this you have to make 667 into a decimal which gives you .67 then you multiply this by 850. This gives you 569.5 people.
X=hamburgers
y=hotdogs
3y+2x=8.00
AND
2y+3x=8.25
Now we've got a system of equations!
Choose a method to solve it, and I think you'll be good from there.
If you need more guidance to the answer, tell me in the comments.
BEST OF LUCK:)
This is a parabola that opens downward.
Remember that the axis of symmetry is located at x=-b/(2a).
So the vertex is at (3,-1)
So functions slope is positive or increasing on (-co, 3] and decreasing on [3,co).
