8+9+10 = 27
27/3 = 9

4+5+6 = 15
15/3 = 5

This is always so, because the third number has one extra that can be added to the first to make them 3x the same numbers.

A1= -26. d= 200<br> a(n)= ?

ziro4ka [17]

Answer:

a(n) = -26+(200n-200)

Step-by-step explanation:

The formula for arithmetic series is "Tn=a+(n-1)d

Then,the elements in the formula are substituted with numbers.i.e Tn= -26+(n-1)200.

therefore,Tn= -26+(200n-200)...

Elyria Warehousing desired to locate a central warehouse to serve five Ohio markets. Placed on a grid system, its five markets h

Iteru [2.4K]

Answer:

The correct option is 2.

Step-by-step explanation:

According to the the center-of-gravity technique, the coordinates of the center-of-gravity location are

$(\frac{\sum x_iL_i}{\sum L_i},\frac{\sum y_iL_i}{\sum L_i})$

Where ( $(x_i,y_i)$ represent the coordinates and $L_i$ is demand.

We have to find the Y-coordinate of the center-of-gravity location.

The sum of product of demand and corresponding y coordinates is

$\sum y_iL_i=65\times 2200+55\times 900+95\times 1300+200\times 1750+175\times 3100=1208500$

The sum of demanded units is

$\sum L_i=2200+900+1300+1750+3100=9250$

The Y-coordinate of the center-of-gravity location is

$y_0=\frac{\sum y_iL_i}{\sum L_i}$

$y_0=\frac{1208500}{9250}$

$y_0=130.6486$

$y_0\approx 131$

The Y-coordinate of the center-of-gravity location is 131. Therefore the correct option is 2.
