Well if the paint covers 256 sq ft, all you have to do is divide that by 4 (because you have 4 square walls) and you get an answer of 64 sq ft. So each wall would be 8ft wide, and 8ft tall.
Answer:
1. Has been answered below
2. Degree of freedom is 4
Step-by-step explanation:
Row 1: 12+10+18 = 40
Row 2: 14+18+13 = 45
Row 3: 66+142+210 = 418
Grand total = 40+45+418 = 503
Column 1 : 12+14+66 = 92
Column 2: 10+18+142 = 170
Column 3: 18+13+210 = 241
Total = 92+170+241 = 503
Expected frequencies of diseased workers
92x40/503 = 7.316
170x40/503 = 13.52
241 x 40/503 = 19.165
Expected frequencies of sensitized workers
92x45/503 = 8.23
170x45/503 = 15.20
241x 45/503 = 21.56
2.
Degree of freedom
= (Number of row -1)(number of column - 1)
= 3-1 * 3-1
= 2x2
= 4
Step-by-step explanation:
<em>1 cm = 0.39370079 in</em>
39 * 0.39370079 = 15.35433081
So, 39 cm is equal to 15.35433081 inches.
-3.6h = -10.8
-3.6h / -3.6 = -10.8 / -3.6
h = 3
