McMahon Hall on UW’s North Campus has 11 floors. You observe 7 people entering the elevator on the ground floor. In the absence of additional information, you assume that every person is equally likely to leave the elevator on any floor. What is the probability that on each floor at most 1 person leaves the elevator?

Answers

Answer 1

The probability that on each floor at most 1 person leaves the elevator is approximately 0.00048828125 or 0.0488%.

To determine the probability that on each floor at most 1 person leaves the elevator, we can approach this problem using the concept of independent events.

Let's consider each floor as an independent event where a person can either leave the elevator (event A) or not leave the elevator (event B). We want to find the probability that on each floor, at most 1 person leaves the elevator.

For each floor, there are two possibilities: either 0 person leaves (event B) or 1 person leaves (event A). Since we assume that each person is equally likely to leave the elevator on any floor, the probability of event A (one person leaving) is 1/2, and the probability of event B (no person leaving) is also 1/2.

Since there are 11 floors in total, and each floor's event is independent, we can use the multiplication rule for independent events to find the overall probability.

The probability that on each floor at most 1 person leaves the elevator is:

[tex](1/2)^11[/tex]

This can be calculated as (1/2) multiplied by itself 11 times.

Therefore, the probability is approximately:

0.00048828125

So, the probability that on each floor at most 1 person leaves the elevator is approximately 0.00048828125 or 0.0488%.

Jen weighs 100 pounds, Jack weighs 120 pounds, and Billy weighs 80 pounds. What is their average weight?

Answers

Answer:

100 pounds

Step-by-step explanation:

To find their average weight, add all of their weights together then divide it by 3

(100 + 120 + 80) / 3

300 / 3

= 100

So, their average weight is 100 pounds

100 + 120 + 80 = 300

What is the height and area of the polygon?

Answers

Answer:

Below in bold.

Step-by-step explanation:

If we draw a line  from top right vertex perpendicular to the  bottom line we get a right triangle.

Height of this triangle = sqrt(5^2 - 3^2) = 4.

This is also the height of the polygon.

The polygon is a trapezium so:

Area of the polygon = 1/2(5 + 8) * 4

= 6/5 * 4

= 26 m^2.

Mr. Hartman, the school librarian, is ordering new keyboards and mice for all of the school's computer labs. Each keyboard costs $13.50, and each mouse costs $6.50. There are 3 computer labs in the school, and each computer lab has s computer stations. Pick all the expressions that represent how much Mr. Hartman will spend on new keyboards and mice.

Answers

Answer:

3 * 20s

Step-by-step explanation:

In order to find out how much Mr. Hartman will spend in total we first need to multiply the price of the keyboard and mouse by the number of computers in a single computer station. Once we have these products we add them together. Finally, we multiply this new value by 3 since there are a total of 3 computer stations. If we turn this into an expression it would be the following...

3 * (13.50s + 6.50s)

We can even simplify this by first adding the cost of the keyboard and mouse and then multiplying by s

3 * 20s

the sum of 8 and B is greater than 22

Answers

Given:

The sum of 8 and B is greater than 22.

To find:

The inequality for the given statement and its solution.

Solution:

We know that, sum of two number is the addition of two numbers.

Sum of 8 and B = 8+B

It is given that, the sum of 8 and B is greater than 22.

[tex]8+B>22[/tex]

Subtracting 8 from both sides, we get

[tex]8+B-8>22-8[/tex]

[tex]B>14[/tex]

Therefore, the required inequality for the given statement is [tex]8+B>22[/tex] and the solution is [tex]B>14[/tex].
