The values of x and y are 8 and 10, respectively

<h3>How to determine the values of x and y?</h3>

The list of the numbers is given as:

4, 7, x, y, 11

The mean and median of the five numbers are the same.

The median is the middle number.

So, we have

Median = x

This means that

Mean = Median = x

The mean is calculated as:

Mean = Sum/Count

This gives

(4+ 7+ x+ y+ 11)/5 = x

Evaluate the sum

(22 + x + y)/5 = x

This gives

22 + x + y = 5x

Evaluate the like terms

4x = 22 + y

Based on the order of the list, we have:

7 < x < y < 11

Assume y = 10

4x = 22 + 10

This gives

x = 32/4

x = 8

Recall that:

7 < x < y < 11

This means that

7 < 8 < 10 < 11

The above is true

Hence, the values of x and y are 8 and 10, respectively

Okay so sorry I’m not very smart when it comes to math but how do I write 2.3181818181818 (it’s a repeating decimal) as a mixed
Alex_Xolod [135]
It is a mixed repeating decimal bc no 3 is not repeating It start at 18
To convert into fraction you take all the decimals (318) then you subtract the non repeating decimal (318-3=315
315 is the nominator
For the denominator you count how many repeating decimal(2) then you put 2 nines For every non repeating decimal you add a zero
315/990. =7/22
2.3181818....= 2(7/22)

Can some1 pls explain to me how to do this??! Katrina is building a deck. She cuts 3 lengths of wood from a 72-inch board. The f
uysha [10]
Rewriting the question, the given lengths that were cut from the board were 30 3/4 inches, 12 1/4 inches, and 16 1/4 inches. To obtain the remaining length of the board, all of the measurements cut are to be added and subtracted from 72 inches. This is shown below:

30 3/4 + 12 1/4 + 16 1/4 = 237/4 = 59.25 inches.

Remaining length of board = 72 - 59.25 = 12.75 inches.

Therefore, there will be 12.75 inches remaining of the board.
