Josh draws a card randomly from a deck, records the suit, returns the card to the deck, and then shuffles the deck. He performs

500 trials. Explain how to use the probability model to predict how many times Josh can expect to draw a card that is a spade.

Answer:

125

Step-by-step explanation:

The probability of getting a spade is 14/56. We multiply 14/56 times 500 that equals 125. I think Josh will get a spade 125 times out of 500.

Two families stayed at the same hotel in identical rooms. The first family stayed for 5 nights and paid extra to use a rollaway
Vesna [10]

Part A: The system of equations that can be used is

5h + 2b = 413

3h + b = 243

Part B: The cost per night of renting a room is $73 and the cost per night using a roll away bed is $24

Step-by-step explanation:

Two families stayed at the same hotel in identical rooms

  • The first family stayed for 5 nights and paid extra to use a roll away bed for 2 of the nights.
  • Their total bill was $413
  • The second family stayed for 3 nights and used a roll away bed for 1 night.
  • Their total bill was $243

We need to write a system of equations that can be used to find, h, the cost per night of renting a room at the hotel, and b, the cost per night of using a roll away bed at the hotel and find the values of h and b using the elimination method

Part A:

∵ The first family stayed for 5 nights

∵ The cost of the renting room per night is $h

∴ The cost of the five nights = 5h

∵ The first family paid extra to use a roll away bed for 2 of the nights

∵ The cost of the roll away bed per night is $b

∴ The cost of the two nights = 2b

∵ Their total bill was $413

∴ 5h + 2b = 413 ⇒ (1)

∵ The second family stayed for 3 nights

∵ The cost of the renting room per night is $h

∴ The cost of the five nights = 3h

∵ The first family paid extra to use a roll away bed for 1 of the night

∵ The cost of the roll away bed per night is $b

∴ The cost of the two nights = b

∵ Their total bill was $243

∴ 3h + b = 243 ⇒ (2)

The system of equations that can be used is

5h + 2b = 413

3h + b = 243

Bart B:

∵ 5h + 2b = 413 ⇒ (1)

∵ 3h + b = 243 ⇒ (2)

- Multiply equation (2) by -2 to eliminate b

∴ -6h - 2b = -486 ⇒ (3)

- Add equations (1) and (3)

∴ -h = -73

- Multiply both sides by -1

∴ h = 73

Substitute the value of h in equations (1) or (2) to find b

∵ 3(73) + b = 243

∴ 219 + b = 243

- Subtract 219 from both sides

∴ b = 24

The cost per night of renting a room is $73 and the cost per night using a roll away bed is $24

 What is the distance from P(2, –5) to the line y = –8? <br>a. –6 <br>b. 3 <br>c. 5<br> d. 10
hjlf
Plotting that point puts us at a y value of -5 (the y coordinate of the point P). y=-8 is a straight horizontal line through y=-8, so the distance from -5 to -8 is 3.  Remember that distance is never negative.  Distance is measured using the absolute value of the numbers. So b is your choice.

What are the domain and ra<br> range of the function (x) = 4x+52
SOVA2 [1]

Answer:

x = all real values

y = all real values

Step-by-step explanation:

The domain is the input values

f(x) = 4x+52 which is a line

The input or x values can be any value so the domain is all real values of x

The range is the output values

f(x) = 4x+52 which is a line

The output or y values can be any value so the domain is all real values of y
