Question

ASAP PLEASE HELP An ostrich egg has a mass of 1.2 kg to the nearest tenth of a kilogram. Find the minimum and maximum possible measurements.

Answer 1

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:-

$\frac{1}{2} \times \frac{1}{10}=\frac{1}{20}$

Now, the maximum value will be equal to calculated amount plus the error in measurement of value .i.e.

$\text { Maximum value }=1.2+\frac{1}{20}=1.2+0.05=1.25$

Now, the minimum value will be equal to calculated amount minus  the error in measurement of value .i.e.

$\text { Minimum value }=1.2-\frac{1}{20}=1.2-0.05=1.15$

Hence, maximum possible measurement is 1.25 Kg

And the minimum possible measurement is 1.15 kg
