In a normal distribution, 95% of the data falls within 2 standard deviations of the mean

Suppose that x and y are both differentiable functions of t and are related by the given equation. use implicit differentiation with respect to t to determine startfraction dy over dt endfraction in terms of x, y, and startfraction dx over dt endfraction .

Atransformation t : (x, y) (x-5,y +3) the image of a(2,-1) is
