What is the solution of the system? Use elimination.<br><br> 3 (-5x-2y=6)<br> 3x+6y=6

Iteru [2.4K]

Answer:

x = -2 and y = 2

Step-by-step explanation:

The given equations are :

-5x-2y=6 ...(1)

3x+6y=6 ...(2)

Multiply equation (1) by 3. SO,

-15x-6y=18 ...(3)

Adding equation (2) and (3).

3x+6y-15x-6y = 6+18

-12x = 24

x = -2

Put the value of x in equation (1).

-5(-2)-2y=6

10-2y=6

4=2y

y = 2

So, the value of x is -2 and y is 2.

Imagine an experiment with 20 groups, and within each group, there are 50 participants. How many degrees of freedom are there fo

Yuliya22 [10]

Answer: There are 980 degrees of freedom for the within subjects factor.

Step-by-step explanation:

Since we have given that

Number of groups = 20

Number of participants in each group = 50

So, number of participants in 20 groups is given by

$20\times 50\\\\=1000$

As we know that

Degrees of freedom for the within subjects factor would be

$v=n-k\\\\v=1000-20\\\\v=980$

Hence, there are 980 degrees of freedom for the within subjects factor.
