a) Is 7.44 You would do 33.98 - 26.54 (Dish w/ Salt Water - Dish)

b) Is 2.74 You would do 29.28 - 26.54 (Dish w/ dried salt - Dish)

c) Is 4.7 You would do 7.44 - 2.74 ( Mass of salt water - Mass of dried salt)

Let me know if this helped you! Have a wonderful night and good luck tomorrow! You got this! :)

An editor has a stack of k documents to review. The order in which the documents are reviewed is random with each ordering being

ladessa [460]

Using the probability concept, it is found that there is a $\mathbf{\frac{1}{k}}$ probability that “Relaxation Through Mathematics” is first to review.

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem:

There is a total of k documents to be reviewed, hence $T = k$ .
Of those documents, 1 is named “Relaxation Through Mathematics”, hence $D = 1$

The <em>probability </em>is:

$p = \frac{D}{T} = \frac{1}{k}$

Ticket for football final selling well, on Thursday 4/7 of the tickets are sold, on Friday 1/4 of the tickets are sold, What fra

sergij07 [2.7K]

Answer:

5/28

Step-by-step explanation:

1/1 represents the whole amount of tickets.

4/7 are sold on Thursday.

an additional 1/4 are did on Friday.

fraction of available tickets on Saturday are therefore

1/1 - 4/7 - 1/4 = 4/1 - 16/7 - 1/1 = 28/1 - 16/1 - 7/1 = 5/1

that means out of 28 equal parts of the total number of tickets 16+7 = 23 parts have been sold.

so, there are only 5 out of the total 28 parts available on Saturday, and the fraction of available tickets is therefore 5/28.

we could have also tried to bring both fractions to the same denominator, and found that this is 28.

and then

4/7 + 1/4 = 4/4 × 4/7 + 7/7 × 1/4 =

= 16/28 + 7/28 = 23/28

and the whole is 28/28.

so we have 28/27 - 23/28 = 5/28 left.

surprise, surprise, it is the same result ...
