You and two friends rent a hotel room that costs $30 so you both put in $10 each later that night the owner of the hotel realize

s he has overcharged you so he sends the bellhop with $5 the bellhop steals $2 and returns $1 to each of you you each paid $9.$9 times $3 =$27 the bellhop has stole $2 that equals $29 what happened to the last dollar

They paid $30, but the owner returned $5, which means the cost is only $25. The bellhop knows this, so he take $2 of the $5 leaving $1 to be return to each person. That means that they each paid $9 making it a total of $27, more than the cost of the room. You don't need to add $2 to the $27, because that wasn't the cost of the room. The cost was only $25, so +$5 =30. So no money is actually missing, they just added incorrectly.

The dollar didn't go anywhere! The question isn't correct because the money the bellhop stole is supposed to be subtracted, not added. So if we subtract $2 we have $25, and that's how much money the owner got, the men got $3 back and the bellboy got $2.

So the owner gets $25, the men get $3 and the bellboy gets $2, and that equals 30.

Question 2:
Ugo [173]

With the frequecy distribution shown in the 50 cities of pakistan,

  • range = 18
  • mean = 18.1
  • median = 19.8333
  • mode = 19.125
  • kurtosis = 2.7508
  • Standard deviation = 3.75

<h3>How to find the Range</h3>

= highest value - lowest value

= 26.5 - 8.5

= 18

<h3>How to find the mean</h3>

= ∑ f x / ∑ f

= ∑ f x / N

= 905 / 50

= 18.1

median

= lower limit + ( N/2 - C ) * h / ( frequency of the class interval )

C = cumulative frequency preceeding to the median class frequency

h = class interval

= 18.5 + ( 50 / 2 - ( 5 + 12 ) ) * 3 / 18

= 18.5 + 1.3333

= 19.8333

<h3>How to find the mode</h3>

The mode is the value with the highest frequency occurence. This is under class 18 - 20

mode = lower limit + ( ( f1 - f0 ) / (2*f1 - f0 - f2 ) ) * h

f1 = fequency of the modal class

f0 = freqency of the preceeding modal class

f2 = frequency of the next modal class

h = class interval

= 18.5 + ( ( 18 - 12 ) / (2 * 18 - 12 - 8 )  ) * 3

= 18 + ( 0.375 ) * 3

= 19.125

<h3>How to find the standard deviation </h3>

= sqrt ( 1 / N ∑ f ( x - x' )^2 )

= sqrt (1  / 50 * 706.5

= 3.7589

<h3>How to solve for relative dispersion </h3>

=  standard deviation / mean

= 3.7589 / 3

= 1.2530

<h3>What is the variance? </h3>

= ( standard deviation )^2

= ( 3.7589 )^2

= 14.1293

<h3>How to solve for kurtosis</h3>

=  ∑ f ( x - x' )^4 / ( N * ( standard deviation )^4 )

= 27459.405 / ( 50 * 3.7589^4 )

= 2.7509

Round 75 to the nearest hundredth
djverab [1.8K]

Answer:

Hundredth? Hundredth is for decimals. If you meant to the nearest Hundred, then it's 100.

Step-by-step explanation:

If you actually meant hundredths though, then it would be 75, because 75 doesn't have any decimals

The value of a car decreases linearly with time. The car was bought new for $62,000 and had a value of $41,000 after 6 years.
guapka [62]
62000-41000=21000
21000/6=3500
3500= 5.64516129% of 62000

Work our the surface area of this cylinder?
tankabanditka [31]

Answer:

A=522.97\ \text{cm}^2

Step-by-step explanation:

Given that,

The diameter of the cylinder, d = 8 cm

Radius, r = 4 cm

Height of the cylinder, h = 16.8 cm

We need to find the surface area of this cylinder. The formula for the surface area of the cylinder is given by :

A=2\pi r^2+2\pi rh\\\\=2\pi r(r+h)\\\\=2\times \dfrac{22}{7}\times 4\times (4+16.8)\\\\=522.97\ \text{cm}^2

So, the surface area of the cylinder is 522.97\ \text{cm}^2
