Can you find sets of positive integers that satisfy the following?

Hitman42 [59]

Answer:

{ 6 ,6 , 6, 7 , 10 } , { 5 , 6 , 6 , 8 , 10 } , { 4 , 6 , 6 , 9 , 10 } , etc. (There's a lot more)

Explanation:

Mean of a set is equal to the terms added divided by the number of terms.

Median is the middle number when you order out the terms in the set in the increasing order from left to out.

Mode is the most occurring term.

Now, since the mean of five number

{ v , w , x , y , z } is 7 , we have: v + w + x + y + z 5 = 7 => v + w + x + y + z = 35

Now, the middle term, the median, is 6.

Now we have:

{ v , w , 6 , y, z }

Since the mode is 6, there has to be at least two 6.

There isn't enough limitations to have one answer.

For example, you could have this:

{ 4 , 5 , 6 , 6 , 14 }

The values add up to 35, the middle term is 6, and 6 is the most occurring.

You will find many other sets possible.

Dafna11 [192]

Answer:

The value of account after 8 years is $8580

Step-by-step explanation:

Given in question as :

The principal that invested in an account = $6,000

The annual interest rate compounded quarterly = 4.5%

Time period = 8 years

Now from compound Interest method for quarterly .

Amount = Principal $( 1 + \frac{Rate}{4 \times 100})^{4 \times Time}$

Or,Amount = $6,000 $( 1 + \frac{4.5}{4 \times 100})^{4 \times 8}$

Or, Amount = $6,000 (1.430)

∴ Amount = $8580

Hence the value of account after 8 years is $8580 Answer
