Which two models would be most useful in predicting weather?
A. A mathematical model based on data
B. A plastic model of a cloud
C. A map that shows wind patterns
D. A peach used to represent Earth

Answers

Answer:

A. A mathematical model based on data

A mathematical model based on data and a map that shows wind patterns   would be most useful in predicting weather as it they will provide data with most accuracy.

What is accuracy?

Accuracy in terms of chemistry can be defined as to how close a measurement is to the true value.There are three types of accuracy:

1) Point accuracy-It means accuracy is present at that point of scale only.It does not give any information about the accuracy of the instrument.

2)Percentage of true value--It is the accuracy  which is determined by identifying accuracy of the instrument  and comparing it with the measured true value.

3)Percentage of scale range- It is the accuracy  which determines accuracy of the measurement.

Accuracy in case of instruments  is neglected up  to ±0.5 percent.
