Given the exponential model y= 200(.80)^x, tell whether the model represents exponential growth or decay. Then, tell what the gr

BaLLatris [955]

This function represents exponential decay.

We know it's exponential because the value the base (200) is being multiplied by is being raised to the power of x.

In this case, the multiplication value is 0.8, which is less than 1.

If the multiplication value is less than 1, than the function will decay, rather than grow.

In this case, the factor is 0.8, or 80%.

Two students, A and B, are working independently on homework (not necessarily for the same class). Student A takes X = Exp(1) ho

OleMash [197]

Answer:

a) The CDF of X/Y is calculated as:

$F_{z} (\zeta) = \frac{\zeta}{\zeta + 2}$ for $0 < \zeta < \infty$

$F_{z} (\zeta) = 0$ for $\zeta \leq 0$

Note: Z = X/Y

b) Probability that A finishes before B = 1/3
