A hotel has a total of 172 rooms. About 58% of the hotel rooms have 2 queen beds in each room and the rest of the rooms have 1 king bed. How many rooms have queen beds?

Answers

Answer:

99.76 = 100

Step-by-step explanation:

Answer:

Queen rooms: 99.76 but since it is a real world problem round it to the nearest tenth

king rooms: 72

Step-by-step explanation:

172 x 58% or 172 x 0.58= 99.67.

rounded = 100.00

172 - 100 = 72

100= queen rooms

72= king rooms

(-15,-6), (8,3) Find the slope of the line through each pair of points?

Answers

Slope is equal to the change in

y

over the change in

x

, or rise over run.

m = change in y / change in x

The change in

x

is equal to the difference in x-coordinates (also called run), and the change in

y

is equal to the difference in y-coordinates (also called rise).

m = y^2 - y^1 / x^2 x^1

Substitute in the values of

x

In a laboratory experiment, two mice will be placed in a simple maze with one decision point where a mouse can turn either left (L) or right (R). When the first mouse arrives at the decision point, the direction it chooses is recorded. Then, the process is repeated for the second mouse.

The tree diagram should be drawn where the first stage represents the decision made by the first mouse and the second stage represents the decision made by the second mouse.

Determine all four possible decision outcomes for the two mice.


Using the information from the previous problem, answer the following question.

If the probability of turning left is 0.5 and the probability of turning right is 0.5 for each mouse, what is the probability that only one of the two mice will turn left?

13) A football team completed three passes for 18 yards each and two runs for 12 yards each, but was also assessed four penalties which cost them 5 yards each. Write a numerical expression which would determine how many yards they have gained or lost.

Answers

Answer

18(2)+12(2)-4(5)

36+24-20

60-20

40

Step-by-step explanation:

since they had two-18 yard passes and two 12 yard runs, that's the first part of the expression, and then they had four penalties that cost them 5 yards, and that was the last term. When you simplify, you end up with 40 yards gained.

In math

Passes: 18(2)

Runs: 12(2)

Penalties:4(5)

equation

18(2)*12(2)-4(5)
