Answer:
18 unit
Step-by-step explanation:
By plotting the given points on the coordinate plane ( shown below )
We get a rectangle.
Suppose ABCD is a rectangle such that,
A≡(-1,1), B≡(3,1), D≡(3,-4) and C≡(-1,-4),
By the distance formula,
∵ Perimeter of a rectangle = 2 ( sum of any two adjacent sides )
Thus, the perimeter of the rectangle ABCD = 2(AB + BC)
= 2(4+5)
= 2(9)
= 18 unit
The median of the data set is 24. What is the greatest possible value of the missing number
The "Unit Price" (or "unit cost") tells you the cost per liter, per kilogram, per pound, etc, of what you want to buy.
Just divide the cost by the quantity:
Example: 2 liters for $3.80 is $3.80/2 liters = $1.90 per liter. Hope this helps!
