y = -x

Step-by-step explanation:

(0, 0) and ( -100, 100)

m= (y2-y1)/(x2-x1)

m=(100-0)/( -100 -0)

m = 100/ -100

m = -1

y - y1 = m(x - x1)

y - 0 = -1(x - 0)

y - 0 = -x + 0

y = -x

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

Answers

Answer:

6 classes

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:

2^5 = 32 < 502^6 = 64 > 50

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

So 6 classes should be used.
