Pie
I’m guessing you meant central tendency.

I’d say the mean is the best measure for period 2. This is because it doesn’t have any extremely low or high values which could distort the mean value.

If it did ie. 8, then I would choose median as it is less affected by anomalous results

The length of a rectangle is the width minus 3 units. The area of the rectangle is 40 units. What is the width, in units, of the
Eva8 [605]

The width of rectangle is 8 units.

Step-by-step explanation:

Given,

Area of rectangle = 40 units

Width = w

Length = w-3

Area = Length * Width

40=(w-3)*w\\40=w^2-3w\\w^2-3w=40\\w^2-3w-40=0

Factorizing the equation

w^2-8w+5w-40=0\\w(w-8)+5(w-8)=0\\(w-8)(w+5)=0

Either,

w-8=0         => w=8

Or,

w+5=0        =>w= -5

As width cannot be negative, therefore

Width of rectangle = 8 units

The width of rectangle is 8 units.

Answer:

What is the perimeter of a rectangle that is 18 inches wide and 23 inches long?

P = 2(l+w)

l = 23, w = 18

P = 2(23 + 18)

P = 2(41)

P = 82

So the perimeter of the rectangle is 82 inches.

Hope this helped! Have a great rest of your day! :)
