Step-by-step explanation:
This is a difference of squares that has the form and factors to:

Here take the square root of each term for the factors.

Answer:
k = 4 ;
N = 52
Step-by-step explanation:
Given the ratio F(3, 48)
F takes in degree of freedom values; degree of freedom of groups ; degree of freedom of error
Hence,
df group or treatment = 3
df error = 48
df treatment = k - 1
k = Number of groups
3 = k - 1
3 + 1 = k - 1 + 1
4 = k
Number of treatment condition = 4
df error = N-k
N = total number of observations
48 = N - 4
48 + 4 = N - 4 + 4
52 = N
Answer:
1 : 64
Step-by-step explanation:
We require the dimensions to be the same units
1 foot = 12 inches , then
85
feet =
× 12 = 256 × 4 = 1024 inches
Scale is then
16 in : 1024 in ( divide both parts by 16 )
= 1 : 64
Answer: We can't answer you if you don't say the problem.
Answer: 53
Step-by-step explanation:
The original square had a dimension of x and x was reduced by 2 which means x-2 and 3 was added so the formula will be x-2+3=54 and to work that out you have to do it backwards.
54-3=51
51+2=53
So the original dimension was 53inches
