The ratio (red to blue) of the perimeters of the similar triangles is 12:7
Assuming that the similar triangles are equilateral triangles, then all their sides will be equal.
Perimeter of a triangle = s1 + s2 + s3
For the red triangle;
Perimeter of the red triangle = 12 + 12 + 12
Perimeter of the red triangle = 36
For the blue triangle:
Perimeter of the blue triangle = 7 + 7 + 7
Perimeter of the blue triangle = 21
Taking the ratio of their perimeters;
Ratio of red to blue = 36:21 = 12:7
Hence the ratio (red to blue) of the perimeters of the similar triangles is 12:7

An activity made by the school with the school in the school, but is not graded and doesn’t take any part during the grading process
Answer:
The correct answer is to compare.
For a reader to compare two or more things, the reader must consider how things are different.
Another option for the sentence could be to contrast. Compare or contrast are equally right,
A good reader needs to understand the different concepts contained in a text. If the reader does not understand the differences it would be difficult for it to have a clear idea and reach a valid conclusion. So, in order to do this, the reader has to compare ideas, propositions, theories or any other element that helps him recognize the differences.
Using the hypergeometric distribution, it is found that the probability is 0.845 = 84.5%.
--------------------
- The patients are chosen from the sample without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x successes is given by:

The parameters are:
- x is the number of successes.
- N is the size of the population.
- n is the size of the sample.
- k is the total number of desired outcomes.
Combination formula:
is the number of different combinations of x objects from a set of n elements, given as:

--------------------
- 56074 patients, thus

- Sample of 40, thus,

- 235 left against medical advice, thus,
.
The probability that none left against medical advice is P(X = 0), so:


The probability is 0.845 = 84.5%.
