The question got caught off. Can't read any of the other examples. I can tell you though that ice melting is a physical change, not a chemical change.
The answer for that is definitely true. You're welcome ;).
Answer
Find out the what is the percent error in the measurement, to the nearest tenth of a percent .
To prove
Formula

Where error = | Approx - Exact |
As given
Karen measures the width of a garden plot and records that it is 44.25 meters. Its actual width is 45.5 meters.
Approx value = 44.25 meters
Actual value = 45.5 meters
error = | 44.25 - 45.5 |
= |-1.25|
= 1.25
Put in the formula


Percentage error = 2.7%
Therefore the percentage error is 2.7% .
Answer:
The required probability is 0.0855
Step-by-step explanation:
Consider the provided information.
The daily revenue has mean $7200 and standard deviation $1200.


The daily revenue totals for the next 30 days will be monitored.


As we know 
Substitute
in above formula.

From the standard normal table P( Z >1.3693) = 0.0855
Hence, the required probability is 0.0855
