Next, chad created this graph with ordered pairs that show the possible ratios of the number of damage to defense cards in his deck. what error chad make?

Rewrite 9 log, x2 in a form that does not use exponents. 9log, x = log, x

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.
