Answer: The expected waiting time is
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 =
Probability that a person choose the slow elevator =
So, the expected waiting time would be
Hence, the expected waiting time is

Step-by-step explanation:
I think someone who is a isn't the only person to be there to a good guy is
Using the given function, it is found that:
a) She earns $36 after 26 years.
b) The original function was shifted 3 units to the right and 1 unit up.
<h3>What is the function?</h3>
Her profit in x years after 2015 is given by:
Item a:
She earns $36 after x years, considering that g(x) = 36, hence:
She earns $36 after 26 years.
Item b:
The new function is:
Which can be basically written as:
Hence the original function was shifted 3 units to the right and 1 unit up.

Answer:
Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself.
Step-by-step explanation:
Any line parallel to the given line will have the same slope as does the given line. Here that slope is -9.
The new line passes thru (-2,5).
Therefore, using the slope-intercept form,
5 = -9(-2) + b. Find b: 5 = 18 + b, so b = -13. The equation of the new, parallel line is then
y = -9x - 13 (answer to first question).
If you want the slope of a line perpendicular to the given line, use the "negative reciprocal" of the slope of the given line as the slope of the new, perpendicular line. Thus, the new slope will be -1/(-9), or (+1/9).
Use the slope-intercept form, with slope = (1/9), to find the line perpendicular to the given line that passes thru the given point. Share your work, please.
