In this unit, you worked with geometric proofs. A proof is a logical sequence of justified conclusions that lead from a hypothes
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.

Iodine-125 has a half-life of about 60 days.
Murljashka [212]

62.5 mg sample will remain after 240 days

Step-by-step explanation:

Given

Half-life = T =  60 days

The formula for calculating the quantity after n half lives is given by:

N = N_0(\frac{1}{2})^n

Here

N is the final amount

N_0 is the initial amount

n is the number of half lives passed

The number of half lives are calculated by dividing the time for which the remaining quantity has to be found by half life

The quantity has to be calculated for 240 days so,

n = \frac{240}{60}\\n = 4

Given

N_0 = 1000\ mg

Putting the values in the formula

N = 1000 (\frac{1}{2})^4\\=1000 * \frac{1}{16}\\=\frac{1000}{16}\\=62.5\ mg

Hence,

62.5 mg sample will remain after 240 days

Keywords: Half-life, sample

What is the geometric mean of 8 and 10?
nekit [7.7K]
If the smaller number is x, then the larger number has to be 20 - x in order for the arithmetic mean to be 10, as their sum must be 20.

If the geometric mean is 8 the product of the numbers has to be 64 and so the larger number is 64/x

Solving 64/x = 20 - x gives the quadratic x^2 -20x +64 = 0 so x = 4 or 16.

The two numbers are 4 and 16.
