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.

Triangle HIJ has coordinates H(-3,5), (8,2), and J(-3,-5). Find

Vlad1618 [11]

Answer:

H (x= -3 , y=5)

I (x=8 , y=2)

J (x= -3 , y= -5)

D is the distance between the 2 points so just plug in the x and y cords of each of the corresponding points

so for (HI)

you plug in 2 on the red x

and 8 on the red y

then -3 in the blue x

and 5 in the blue y
