To show the variation in a set of data, what do you calculate?

Pavel [41]

The range is the simplest measure of variation . It is the difference between the biggest and smallest random variable.

Range= maximum value - minimum value

ex. Therefore in the range of these variables: (2,4,4,7} you would do 7 minus 2

Please help I don’t understand this

Darina [25.2K]

Hello from MrBillDoesMath!

Answer:

9/2 > 3/2 (slope of <u>greater than.</u>..)

Discussion:

This seems like an odd question. We can say that

9/2 > 3/2

so the slope of the line with m = 9/2 is greater than (in fact, 3 times greater than) the slope of the line with slope m = 3/2

Thank you,

MrB

if i put 1500 into my savings account and earned 180.00 of interest at 4% simple interest , how long was my money in the bank

tresset_1 [31]

T = ?

i = 180.00

R = 4% ; 4/100 => 0.04

p = 1500

i = p x R x t

180.00 = 1500 x 0.04 x t

180.00 = 60 x t

t = 180.00 / 60

t = 3 years

hope this helps!

How do you find the area of a polygon in a coordinate plane

inna [77]

Step-by-step explanation:

The way that I would do it, would be to use the point distance formula to find the length of each side.

Distance formula: $\sqrt{(x2-x1)^{2} (y2-y1) ^{2} }$

After you use this formula to find the length of all sides of the polygon, you would need to use the appropriate area formula to find the area of the polygon.

Area of Triangle: A= 1/2 base times height

Area of Rectangle: A= length times width

Area of Square: A= s^2 where s is the length of the side

Area of Parallelogram: A= base times height

Area of Trapezoid: A= 1/2 times height (base 1 + base 2) where base 1 and base 2 are the parallel sides

Area of Kite or Rhombus: A= 1/2 (diagonal 1 times diagonal 2)

Area of Regular Polygons: A= 1/2 (apothem times perimeter)

Archy [21]

Answer:

Area= 80 in square

Step-by-step explanation:

h=8

b=20

formula= b*h/2

so, 8*20/2

Area= 80 in square
