A cake has circumference of 25 1/7 inches. What is the area of the cake? Use 22/7 to approximate π. Round to the nearest hundred
choli [55]

Answer:

50.29 in^2

Step-by-step explanation:

From the circumference we need to find the radius.

Since C = 2*pi*r, r = C / (2*pi).

Here, with C = 25  1/7 in, r = (25  1/7 in) / [ 2(22/7) ], or r = 4 in

The area of the cake is A = pi*r^2, or (here)  A = (22/7)(4 in)^2 = 50.29 in^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.
