Step-by-step explanation:
8(9x-11)
72x-88
<span>First you need to find the mean on these numbers that is step one in finding standard deviation. so this is 44.2. now you need to subtract the mean from each number and square the result. after that step you now have these numbers.... 3.24, 139.24, .64, .4,.64,282.24,116.64,77.44,27.04. now the next step is to find the mean of these numbers. you get 71.9 appx.. now all you do is square root this number you get 8.5 when you round to the nearest thenth</span>
RST is not a right triangle.
<h3>What is a Triangle ?</h3>
A Triangle is a polygon with three sides , three angles and three vertices.
It is given in the question that
triangle RST with coordinates R(2, 3), S(4, 4), and T(5, 0)
It has to be determined that if the triangle is a right angled triangle ,
If we plot the triangle on the coordinate plane , it can be easily seen that the triangle is not a right angled triangle ,
It can also be proved by measuring the length of the sides that if the sum of the squares of the sides is equal to the square of the largest side , then it will be a right triangle or not .
