There are 11 full tables, because when you divide 138 by 12 you get 11 remainder 6. So there is 11, because 12 people are at 11 tables and 6 at one!

True or false the difference of two numbers is less than either of those two numbers
Kisachek [45]
The difference of two numbers is not always less at either of the two numbers. (especially for negative numbers)

Take fo example, 40 - 30 = 10.
Here the difference is less than both two numbers.

But in 40 - 15 = 25
Here the difference is less than one of the numbers but greater than the other number.

Now consider, -3 and -5, their difference is given by (-3) - (-5) = -3 + 5 = 2.
Here, 2 is greater than both -3 and -5.

Therefore, The difference of two numbers is not always less than either of those two numbers.

Your answer is False.

If the following data were transformed, and points with the coordinates
Lilit [14]

Answer:

The points are: <u>( 3 , 0.903) ,  ( 4 , 1.204) and ( 5 , 1.505)</u>

Step-by-step explanation:

The question is as following:

If the following data were transformed and points with coordinates (x,log(y)) were plotted what points would be plotted? Round log Y to three decimal places

<u>From the table:</u>

  • At x = 3 and y = 8 ⇒ (x,log(y)) = ( 3 , log 8 ) = ( 3 , 0.903)
  • At x = 4 and y = 16 ⇒(x,log(y)) = ( 4 , log 16) = ( 4 , 1.204)
  • At x = 5 and y = 32 ⇒(x,log(y)) = ( 5 , log 32) = ( 5 , 1.505)

<u>The points that would be plotted are:</u>

( 3 , 0.903) ,  ( 4 , 1.204) and ( 5 , 1.505)
