A rectangular hotel room is 4 yards by 5 yards. The owner of the hotel wants to recarpet the room with carpet that costs $51.92
Sphinxa [80]

Answer:

it will cost him $2204 to recarpet the room.

Step-by-step explanation:

The floor of the room is rectangular. The formula for determining the area of a rectangle is expressed as

Area = length × width

The rectangular hotel room is 4 yards by 7 yards. It means that the area of the rectangular floor would be

Area = 4 × 7 = 28 square yard.

If the cost of the carpet $58.00 per square yard, the total that it will cost to recarpet the room would be

38 × 58.00 = $2204

Tessa is cooking steak for her family. She wants to be sure the steak has an internal temperature of at least 160 degrees Fahren
Over [174]

Answer:

<u>Population : all the steaks Tessa can cook</u>

<u>Parameter : minimum internal temperature of 160 degrees Fahrenheit</u>

<u>Sample : two random thermometer readings</u>

<u>Statistic : minimum sample reading of 165 degrees Fahrenheit</u>

Step-by-step explanation:

Let's recall the definitions of these statistical concepts and match it with the information that were provided to us:

  • Populations can be the complete set of all similar items that exist, in our case, all the steaks that Tessa can cook.
  • Parameter is is a value that describes a characteristic of an entire population, such as the minimum temperature of the steaks Tessa is cooking in Fahrenheit degrees.
  • Sample is a subset of the population, in our case, the two random readings of the thermometer Tessa did.
  • Statistic is a characteristic of a sample, for our problem, it's the minimum reading of 165 degrees Fahrenheit.

Find the probability that you throw a dart and land in the region labeled G.
Alexandra [31]
1. Check the picture attached. We can calculate the area of the orange region G by dividing it into right triangles with both legs equal to 1.

Area of one triangle is 1/2*1*1=1/2 units square. 
There are 9 in total, so area G = 9/2 units square.

2. The square has side length equal to 10, so the square area is 100 units square.

3. P(landing in G)=Area of G/total area= (9/2)/100=9/200= 0.045

A boat is traveling at 43.2 m/s. It then goes down a faster part of the river and is now going 144
Marina86 [1]

Answer:

Step-by-step explanation:

boat was at 43.2 m/s   speed increase to 144 m/s

if the boat was moving 0 m/s and increased to 144 m/s - 43.2 m/s accelerating at 25.2 m/s²,  it would take the same amount of time

25.2 m/s² × x seconds = (144 - 43.2) m/s      solve for x in seconds

x seconds = 100.8 m/s   /  25.2 m/s²

x seconds = 4 (m/s /ms²)  = 4 (m/s × s²/m)  = 4 seconds   the  units match

x = 4 seconds
