Jillian is using integer tiles to add 7 + (negative 2). She uses the steps below. Step 1 7 positive tiles. Step 2 7 positive til
raketka [301]

Answer:

<h3>Step 4</h3>

Step-by-step explanation:

Given the expression 7+(-2)

Let 7 be 7 positive tiles since it is a positive number

Let -2 be 2 negative tiles being a negative number

7+(-2) = 7 positive tiles <em>and</em> 2 negative tiles

note that + * - will give minus sigh (-), the expression will become:

7+(-2) = 7-2

7-2 = 5

Hence the expression gives 5 positive tiles not 2 positive tiles according to Jillian calculations in step 4.

Hence Jillian made an error in step 4

A Venn diagram is used to present the relationship between sets in a logical form

Please find attached the completed Venn diagrams for the questions with the contents outlined as follows;

1. The set of whole numbers 1 to 15 = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}

Set A = All even numbers in this set

Set A = {2, 4, 6, 8, 10, 12}

2. The set of whole numbers from 1 to 20

Set C = All even numbers = {2, 4,  6, 8, 10, 12, 14, 16, 18, 20}

Set D = All multiples of 4 = {4, 8, 12, 16, 20}

3. The set of all whole numbers from 1 to 20

Set E = {2, 4, 6, 7, 9, 10}

Se F = {3, 4, 5, 9, 10, 13, 15, 16, 19,20}

Leona [35]

Answer:

The right answer is "0.70".

Step-by-step explanation:

The given query seems to be incomplete. Please find below the attachment of the full query.

By using the Bayes' theorem, we get

⇒  P[(X

By putting the values, we get

                                     =\frac{[P(2)+P(3)]}{[1-P(0)-P(1)]}

                                     =\frac{(0.20+0.15)}{1-0.20-0.30}

                                     =\frac{0.35}{0.5}

                                     =0.70
