Example #step 1

Vivek and you may Rupal try sisters, and you can Rupal is actually older than Vivek by the three-years. Sanjeev, the dad, is actually an excellent statistician, in which he was interested in evaluating new linear matchmaking Linear Relationships Good linear relationships identifies the new family members between several distinctive line of details – x and y – in the form of a straight line on the a chart. Whenever presenting an excellent linear relationship through an equation, the value of y is derived through the worth of x, highlighting their correlation. read more between peak and weight.

Hence, as Tom helps make a whole lot more sandwiches, the purchase price increases, and it also seems to be good much more new sandwich, the greater produce are expected, thereby because the cash could be needed.
