The maximum possible measurement is 1.25 Kg and the minimum possible measurement is 1.15 kg
Solution:
Given mass of an ostrich egg is 1.2 Kg
We have to find the minimum and maximum possible measurements to the nearest tenth of a kilogram
The greatest possible error in measurement nearest tenth of a kilogram, is a half a tenth of a kilogram which is:-
![(1)/(2) * (1)/(10)=(1)/(20)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/njxq8emtu2d5vj4t0vw4xe7axhsnv8lx7k.png)
Now, the maximum value will be equal to calculated amount plus the error in measurement of value .i.e.
![\text { Maximum value }=1.2+(1)/(20)=1.2+0.05=1.25](https://img.qammunity.org/2020/formulas/mathematics/middle-school/2rl1xxb5janjz8tnt6wsz64qdmvnz6txpc.png)
Now, the minimum value will be equal to calculated amount minus the error in measurement of value .i.e.
![\text { Minimum value }=1.2-(1)/(20)=1.2-0.05=1.15](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mz05r1k75zwrcb0q9taeksz50jq9nu6r6k.png)
Hence, maximum possible measurement is 1.25 Kg
And the minimum possible measurement is 1.15 kg
