<h2>Answer:</h2>

<u>Total price = Mean price × No. of books</u>

<u>Total price = Mean price × No. of books= $10 × 5 = $50</u>.

<u>Now, we will find the cost of other 3books except expensive price and cheapest price</u>.

$50 - ( $15 + $6)

$50 - $21 = $29.

<u>Cost of the 2 books except middle one</u>,

$29 - $8

= $21.

<u>Now, we need a price which is lower than middle one but higher than cheapest price i.e, 7 so</u>

$21 - $7

= $14.

<u>So, the price of remaining two books are $7 and $14 respectively</u>.

Mean is average. Multiply total books by the mean to find the total cost:

5x 10 = $50 total.

Subtract the highest and lowest prices to find the total of the remaining 3 books.

50 - 15-6 = 29

The median price was 8, this is the middle number, subtract 8 from 29 to get the cost of the last 2 books:

29-8 =21

Now you need a price lower than the median but higher than the lowest cost so that has to be 7

Subtract 7 from 21 to get the cost of the last book 21-7 = 14

The price of the remaining books is $7 and $14

Alejandra's Tapas Bar offers a menu consisting of $9$ savory and $5$ sweet dishes. You can also get a mix-and-match plate consis
Mariana [72]

Answer:

45

Step-by-step explanation:

Given that the number of savory dishes is 9 and the number of sweet dished is 5.

Denoting all the 9 savory dishes by p_1, p_2,...,p_9, and all the sweet dishes by q_1,q_2,...,q_5.

The possible different mix-and-match plates consisting of two savory dishes are as follows:

There are 9 plates with q_1 from sweet plates which are (q_1, p_1), (q_1, p_2), ..., (q_1,p_9).

There are 9 plates with q_2 from sweet plates which are  (q_2, p_1), (q_2, p_2), ..., (q_2,p_9).

Similarly, there are 9 plated for each q_3, q_4 and q_5.

Hence, the total number of the different mix-and-match plates consisting of two savory dishes

= 9+9+9+9+9= 9\times5=45

yuradex [85]

You found $5, so it's positive. You don't put anything in the negative, because you aren't losing anything.
