nordsb [41]3 years ago

Answer:

+12.5%

Step-by-step explanation:

This is rather simple. Subtract 72 from 81, then put the difference over 72. Then, multiply that by 100.

(81 - 72)/72 * 100

<em>Subtract 72 from 81 to get 9</em>

9/72 * 100

<em>Multiply 9 by 100 to get 900</em>

900/72

<em>Simplify the above fraction by cancelling out 9.</em>

100/8

<em>Divide 100 by 8 to get 12.5%</em>

The percent of change is +12.5%

alisha [4.7K]

Mathematical proofs are important because they help to explain concepts. They also serve as concrete validation for a mathematical result or statement.

  • In geometry, an incorrect conclusion within a proof might lead to wrong estimations of size, length, and other spatial properties.
  • Algebra, topology, arithmetics, calculus, and statistics are some other branches of mathematics. In statistics, an incorrect conclusion within a proof might lead to the wrong interpretation of bulky data. Statistical properties like the mean, median, and mode can be misinterpreted.
  • Businesses that rely on statistics for production and forecasting might be affected.

<h3>What is a Mathematical proof?</h3>

A proof in mathematics is a number of conclusions that lead to the justification of a final statement.

Having incorrect mathematical proofs can be dangerous because it will cause the misinterpretation of concepts and the obtaining of wrong results.
