The length of time (in years) until a particular radioactive particle decays is a random variable t with the probability density function by: f(t) = 0.03e^(-0.03t); for t in [0, infinity]find the mean of the distribution, the standard deviation of the distribution, and the probability that the random variable is between the mean and one standard deviation above the mean

there is nothing below so i cannot

step-by-step explanation:

its a, i had the same answer, its from study island right

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
