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.

The number of basketball games that must be scheduled in a league with n teams is given by G(n) = (n2 - n)/2 where each team pla

Pani-rosa [81]

Answer:

There are 7 teams in the league

Step-by-step explanation:

Given that the number of games is given by:

$G(n) = \frac{(n^2-n)}{2}$

The equation will be used to determine the number of games. As we already know, that 21 games are scheduled which means G(n) is 21 so we have to find n when G(n) is 21

Putting this mathematically

$21 = \frac{n^2-n}{2}$

Multiplying equation by 2

$2*21 = 2*\frac{n^2-n}{2}\\42 = n^2-n\\n^2-n-42 = 0\\n^2-7n+6n-42 = 0\\n(n-7)+6(n-7) = 0\\(n-7)(n+6)=0\\n-7 = 0 => n=7\\n+6=0 => n=-6$

As the number of teams cannot be negative, the number of teams in league are 7.

Hence,

There are 7 teams in the league
