A set of data has 50 observations. How many classes would you recommend?​

Step-by-step explanation:

If k is the number of classes and n is the number of observations, then for number of classes we should select the smallest k such that 2^k > n.

We have n = 50 and:

As per above described 2 to k rule, we are taking k = 6.

So 6 classes should be used.

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
