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
9 chairs;
there would have to be nine chairs at a table for it to have the most chairs because in this case, even if the remaining 7 chairs were all located at one of the other tables, then the table with the 9 chairs would still have the most chairs.
The greatest possible error is one half of the measuring unit you're using.
Multiply the unit you use by 1/2:

The greatest possible error will be
1/8 inch.
<u>Answer:</u>
20h + 20
<u>Step-by-step explanation:</u>
5(2h + 4) + 10h
1️⃣ Expand by distributing terms.
<em>10h + 20 + 10h</em>
2️⃣ Collect like terms.
<em>(10h + 10h) + 20</em>
3️⃣ Simplify.
<em>20h + 20</em>
Answer: <em>20h + 20</em>
