A function will not have any repeating x values....it can have repeating y values, but all the x values have to be different for it to be a function.

A is a function because all the x values are a different number
B is not a function because u have repeating x values...u have repeating 4's and repeating 9's

MissTica

Answer:

Perimeter = 86.4 (m)

Step-by-step explanation:

A square (with side x) has an area of 466.56 (m^2)

=> x^2 = 466.56

=> x = sqrt(466.56) = 21.6

=> Perimeter of this square: P = 4(x) = 4(21.6) = 86.4 (m)

Hope this helps!

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.
