Answer: The data set is centered around the mean.
1) x=9, because we can use the Pythagorean theorem, x^2 + 144 = 225, x^2 = 81
2) , because 6^2 +6^2 = 72,
3) , because

Answer:
square metres of plant materials required to support the fox = 3650 m²
Explanation:
From the given information:
the daily caloric requirement of the fox = 800
In a year, we have = 800 kcal × 365 /year = 292,000 kcal/year
Also, only 10% of the energy at a particular trophic level can be passed onto the next.
the net productivity of the plant material = 8000 kcal/m²/yr
So, using 10% of energy at a particular level, the fox only need 80 kcal/m²/yr
The objective is to determine in square meters, how many materials are required to support the fox.
square metres of plant materials required to support the fox =
= 3650 m²
