Ray has wood blocks that are 24 centimeters tall. lora has wood blocks that are 20 centimeters tall. what is the minimum number of blocks that each must use in order to build towers of equal height? how tall will the towers be?

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.
