Atriangle has verticies a(-2, 3), b(0,0), and c (1,1).
find the coordiates of the triangle if it is reflected over the x-axis, then dilated by a scale factor of 3.
after that find the coordinates if the original triangle is dilated by a scale factor of 3, then reflected over the x-axis.

The random variable x has probability density function f (x) = k(−x²+5x−4) 1 ≤ x ≤ 4 or =0 1 show that k = 2/9 find 2 e(x), 3 the mode of x, 4 the cumulative distribution function f(x) for all x. 5 evaluate p(x ≤ 2.5). 6 deduce the value of the median and comment on the shape of the distribution.
