Now that you have a mean value for each treatment, it’s important to examine the variation around that mean. To do so, calculate the standard deviation for each treatment using the following formula: s=1n−1Σ(xi−x¯)2−−−−−−−−−−−√.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other
