Answer:440
Step-by-step explanation:
a is the unknown number
25% of a=110
25/100 x a=110
1/4 x a=110
a/4=110
Cross multiplying we get
a=110 x 4
a=440
a 32 sided polygon I believe
Answer:15b^2-5b^3+24b-16
Step-by-step explanation:
(4-b)(5b^2+5b-4)
Open the brackets
20b^2+20b-16-5b^3-5b^2+4b
Collect like terms
20b^2-5b^2-5b^3+20b+4b-16
15b^2-5b^3+24b-16
Answer:
the answer is 10 5. you welcome
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
