Many electronics follow a failure rate described by an exponential probability density function (PDF). Solar panels are advertis

Answer:

The right answer is "0.3193".

Step-by-step explanation:

According to the question,

Mean,

$\frac{1}{\lambda} = 13$

$\lambda = \frac{1}{13}$

As we know,

The cumulative distributive function will be:

⇒ $1-e^{-\lambda x}$

hence,

In the first 5 years, the probability of failure will be:

⇒ $P(X$

$=1-e^{-(\frac{1}{13} )\times 5}$

$=1-e^(-\frac{5}{13})$

$=1-0.6807$

$=0.3193$

Of the 1,640 students enrolled at a school, 50% come to school by bus, 35% come by car, and the rest of the students walk home.

ehidna [41]

So first we need to find what percent of the students walk to school.

50 + 35 = 85% don't walk leaving only 15% that walk to school,

To find the 15% percent that DO walk we multiply .15 by the total number of people.

.15 x 1640 = 246 people walk to school
