find the set of five items of data that has a range of 9, a mean of 11, a meadian of 12, and a mode of 15.

1 answer:

3 0

Here's what I've done:

Represent the set of 5 items by {a,b,c,d,e}. Assume that these items have already been arranged in ascending order.

The middle item, c, has the value 12.

Since "mode" means "most frequently appearing item," let's assume that d and e are both 15.

If the range is 9, we could then write 15-9 = 6, meaning that a = 6.

Then we have {6,b,12,15,15}

To find b, sum up {6,b,12,15,15}, equate the result to 11, and solve for b.

The difference between 48 and 13 algebra numeral expression.

Sphinxa [80]

Numerical expressions contain numbers, while algebraic expressions contain variables and numbers.

<u>Numerical Expression</u>

"Difference" indicates that we'll be subtracting 13 from 48.

48 - 13 = 35

<u>Algebraic Expression</u>

Variables represent the unknown number, in this case the difference between 48 and 13. Let d represent the difference between the two.

48 - 13 = d

35 = d
