Aparticular country has 55 total states. if the areas of all 55 states are added and the sum is divided by 55, the result is 191 comma 435 square kilometers. determine whether this result is a statistic or a parameter.

It's a parameter.

Step-by-step explanation:

It is a parameter because you have consider the entire population, in this case the states, you have all the data of them (The areas). this would be an statistic if you cosulted a few of them instead.

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
