Answer: she baked 1225 muffins.

Step-by-step explanation:

Let x represent the number of muffins that she baked.

She gave 4/11 of the muffins to her friends. This means that the number of muffins that she gave to her friends is 4x/11. The number of muffins remaining is

x - 4x/7 = 3x/7

She gave 4/7 of the remainder to the guests at the event. This means that the number of muffins that she gave to the guests at the event is

4/7 × 3x/7 = 12x/49

The number of muffins remaining would be

3x/7 - 12x/49 = 9x/49

She had 225 muffins left. It means that

9x/49 = 225

9x = 225 × 49 = 11025

x = 11025/9

x = 1225

The lifetime of two light bulbs are modeled as independent and exponential random variables X and Y, with parameters lambda and
Scorpion4ik [409]

Answer:

\bf h(x)=max(\lambda,\mu) e^{-max(\lambda,\mu) x}\;(x\geq0)

Step-by-step explanation:

The PDF of X is

\bf f(x)=\lambda e^{-\lambda x}\;(x\geq0)

The PDF of Y is

\bf g(x)=\mu e^{-\mu x}\;(x\geq0)

The means of X and Y are respectively,

\bf \displaystyle\frac{1}{\lambda}\;,\displaystyle\frac{1}{\mu}

so we can see that the larger the parameter, the smaller the mean. Hence the PDF of Z = min(X, Y) is an exponential with the largest parameter of the two.

Therefore, the PDF of Z is

\bf h(x)=max(\lambda,\mu) e^{-max(\lambda,\mu) x}\;(x\geq0)
