A building contains two elevators, one fast and one slow. The average waiting time for the slow elevator is 3 min. and the avera

cupoosta [38]

Answer: The expected waiting time is $1\dfrac{2}{3}\ min$

Step-by-step explanation:

Since we have given that

Average waiting time for slow elevator = 3 min

Average waiting time for fast elevator = 1 min

probability that a person choose the fast elevator = $\dfrac{2}{3}$

Probability that a person choose the slow elevator = $\dfrac{1}{3}$

So, the expected waiting time would be

$E[x]=\sum xp(x)=3\times \dfrac{1}{3}+1\times \dfrac{2}{3}\\\\=1+\dfrac{2}{3}\\\\=\dfrac{3+2}{3}\\\\=\dfrac{5}{3}\\\\=1\dfrac{2}{3}\ min$

Hence, the expected waiting time is $1\dfrac{2}{3}\ min$

What is the value of –4.00 –0.25 1.51 2.41

soldier1979 [14.2K]

For this case we must resolve the following expression: $log_ {0.5} (16)$

We have to:

$log_ {a} (x) = \frac {log_ {b} (x)} {log_ {b} (a)}$

The base change rule can be used if a and b are greater than 1 and are not equal to x.

We substitute the values in the base change formula, using $b = 10$

$\frac {log (16)} {log (0.5)} = - 4$

Answer:

-4

What are the coefficients for the binomial expansion of (p+q)^6

seropon [69]

Answer:

1 6 15 20 15 6 1

Step-by-step explanation:

To figure this out, we need to look at Pascal's Triangle, which is a tricky little way to find the coefficients for any binomial expression like this! Check the attached photo.

Because this is to the sixth, we need the 6th row, which is 1 6 15 20 15 6 1. From this, we know that those numbers are the coefficients!
