Answer:
x = 80
Step-by-step explanation:
x + 30 = 110 (Opposite angles are equal)
x = 110 - 30
x = 80
Answer:
3000 mL
Step-by-step explanation:
recall 1 liter = 1000 mL
hence
3 liters = 1000 mL x 3 = 3000 mL
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
