The amount of time, in minutes, that a woman must wait for a cab is uniformly distributed between zero and 12 minutes, inclusive

murzikaleks [220]

Answer:

$P(X\leq x) =\frac{x-a}{b-a}, a \leq x \leq b$

And using this formula we have this:

$P(X$

Then we can conclude that the probability that that a person waits fewer than 11 minutes is approximately 0.917

Step-by-step explanation:

Let X the random variable of interest that a woman must wait for a cab"the amount of time in minutes " and we know that the distribution for this random variable is given by:

$X \sim Unif (a=0, b =12)$

And we want to find the following probability:

$P(X$

And for this case we can use the cumulative distribution function given by:

$P(X\leq x) =\frac{x-a}{b-a}, a \leq x \leq b$

And using this formula we have this:

$P(X$

Then we can conclude that the probability that that a person waits fewer than 11 minutes is approximately 0.917

Answer:

We conclude that the simplified expression is:

$0.10\left(7l\:+\:2s\right)=0.7l+0.2s$

Step-by-step explanation:

Given the expression

$0.10\left(7l\:+\:2s\right)$

Apply the distributive law: a(b+c) = ab+ac

a = 0.1, b = 7l, c = 2s

$0.10\left(7l\:+\:2s\right)=0.1\cdot \:7l+0.1\cdot \:2s$

$=7\cdot \:0.1l+2\cdot \:0.1s$

$=0.7l+0.2s$

Therefore, we conclude that the simplified expression is:

$0.10\left(7l\:+\:2s\right)=0.7l+0.2s$
