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
Each piece should be 4.2 feet
the whole rope is 21 feet long and you divide it by 5 because you want 5 equal pieces.
21/5 (21 divided by 5) equals 4.2 feet
Answer:
Remembering the properties of numbers is important because you use them consistently in pre-calculus. The properties aren't often used by name in pre-calculus, but you're supposed to know when you need to utilize them.
Answer:
approximately 72.35 minutes
Step-by-step explanation:
there are 1609.344 meters in a mile
john ran 100 meter - which would be 16.09 per mile
9.88 seconds x 16.9 = 166.97 seconds per mile
166.97 seconds x 26 miles = 4341.22 seconds
4341.22 seconds / 60 = 72.35 minutes
12 - x = 5
Subtract 12 from both sides
12 - 12 - x = 5 - 12
- x = - 7
Divide both sides by -1
-x/-1 = -12/-1
x = 7
