Jill's tomato plant is growing. Five days after she planted it, it was 4 cm tall. Thirty days after she planted it, it was 16.5 cm tall. Determine and interpret the rate of change and initial value. Show all work

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.
