The reading given by a thermometer calibrated in ice water (actual temperature 0°c) is a random variable with probability density function where k is a constant.
f(x) = k(1 - x^2) for -1 < x < 1
f(x) = 0 for otherwise
(a) find the value of k.
(b) what is the probability that the thermometer reads above 0°c?
(c) what is the probability that the reading is within 0.25°c of the actual temperature?
(d) what is the mean reading? what is the median reading? what is the standard deviation?

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2
