Answer:

0.2

Step-by-step explanation:

R can be as small as -1 to display a perfect negative linear relationship or as large as 1 to display a perfect positive linear relationship. The closer the r-value is to 0 the weaker the correlation so therefore 0.2 is closest to 0 making it the answer choice with the weakest correlation.

0.01 is one tenth of what

AleksAgata [21]

So to find a tenth of a number, we divide the number by ten
Since we want to do the opposite, we multiply the number by ten
Therefore, .01*10 is .1
So, .01 is a tenth of .1
.1 is the answer
Hope this helped!! :D

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
