Apencil bag contains 20 red pencils. 12 pencils, and 10 green pencil, carrie randomly selects a red pencil followed by a green pencil without replacement. what is the probability that carrie selects a red pencil followed by a green pencil? write the answer as a percent rounded to the nearest tenth of a percent.

11.6%

Step-by-step explanation:

On the first selection, there are 20 red pencils out of 42 total pencils.

On the second selection, there are 10 green pencils out of 41 pencils left over.

So the probability is:

(20/42) (10/41)

100/861

≈11.6%

The number of days are independent and the total number of minutes are dependent.

The required model for the situation is

The table is shown below:

Step-by-step explanation:

Consider the provided information.

Joshua spends 25 minutes of each day reading. Let d be the number of days that he reads, and let m represent the total minutes of reading.

We need to determine which variable is independent and which is dependent.

Here, the number of days are independent and the total number of minutes are dependent.

If he spends 25 minutes each day. So the total number of minutes in d days are:

The required model for the situation is

Now make the table which showing the number of minutes spent reading over 7 days.

Substitute the value of d from 1 to 7 in

Number of days(D)        Minutes(M)

          1                                 25

          2                                 50

          3                                 75

          4                                 100

          5                                 125

          6                                 150

          7                                 175
