Consider various ways of ordering the letters in the word TENNESSEE. TENENESES, EESSENNET, TNNEESSEE, and so on. (a) How many di

scoundrel [369]

Answer:

3780.

Step-by-step explanation:

To solve this we will start by just considering the number of ways to arrange 9 objects. We can do this in 9! ways.

However since we have 3 reoccurring letters in Tennessee namely n,s and e we need to remove the times these form the same arrangement. Let me give an example to show what this means. Lets say we have the arrangement:

ennetssee

Now what happens if we exchange the places of the letters n for example? Of course we get the same arrangement of letters. We don’t want to count these as 2 different arrangements since for our interests they are the same. We therefore divide 9! by the number of times this type of double counting occurs.

Since the word has the letter n occurring twice we will start by diving by 2! .

The letter s occurs 2 times as well so we will have to divide by 2! again.

Finally the letter e occurs 4 times and so we will have to divide by 4! here.

Now we get the following result:

9/(2 x 2 x 4)=3780.

So in conclusion there are 3780 different ways to arrange the letters in Tennessee.

During a week-long dry spell, the water level in a pond decreased by 4 in. Per day, except for two days when it decreased by hal

Helga [31]

Answer:

24 inches.

Step-by-step explanation:

Given:

During a week the water level in a pond decreased by 4 in. Per day,

For two days, it decreased by half that amount = $4\times\frac{1}{2}=2\ inches\ per\ day$

Question asked:

How much did the water level decrease in the pond in one week?

Solution:

As we know, there are 7 days in a week.

For 5 days,

Each day water level decreased by = 4 inches

In 5 days, water level decreased by = $4\times5=20\ inches$

For exceptional 2 days:

Each day water level decreased by = 2 inches

In 2 days, water level decreased by = $2\times2=4\ inches$

Water level decreased in whole week = 20 + 4 = 24 inches

Therefore, water level decreased 24 inches in the pond in one week.
