Answer:
The slope is undefined
Step-by-step explanation:
The change in x is 0. So you have change in y over 0, which is undefined.
Step-by-step explanation:
Consider a function
f
(
x
)
which is twice differentiable. The graph of such a function will be concave upwards in the intervals where the second derivative is positive and the graph will be concave downwards in the intervals where the second derivative is negative. To find these intervals we need to find the inflection points i.e. the x-values where the second derivative is 0.
Asserting a <em>cause - and - effect </em><em>relation</em><em>ship</em> with highly correlated variables may sometimes be misleading due to the presence of a possible lurking or confounding variable.
Lurking variables cause unintended or spurious association between correlated variables. In the scenario described, a possible confounding variable may be weariness or Fatigue which whereby the mother finds it easier to bottle feed as they have become psychologically disturbed and are prone to be more receptive during these period.
Hence, fatigue is a possible lurking variable in this scenario.
