lidiya [134]

Answer:

<u>All the four statements are true , which are -</u>

(A) The subset contains contains of all the outfits that have grey slacks .

(B)  The subset contains contains of all the outfits that have grey slacks and red tie .

(C) The subset contains contains of all the outfits that have grey slacks and blue shirt .

(D)  The subset contains contains of all the outfits that do not have black slacks .

Step-by-step explanation:

<u>We are given with Outfit 2 , 4 and 6</u>

Outfit 2 -   Blue     grey     red

Outfit 4 -   White    grey     red

Outfit 6   - Black     grey    red

(A) Since only 2,4, and 6 contain grey slacks, and no other outfit contains grey slacks, those are the subsets that contain grey slacks. Thus , this statement is true .

(B) Just outfits 2, 4, and 6 have grey slacks and a red tie, proving the statement. Other clothes do not include grey slacks and a red tie; they may include a red tie but not both grey slacks and a red tie. Hence , the statement is true .

(C) Since the outfit 2 has grey slacks and a blue shirt, the statement is correct; no other outfit has both grey slacks and a blue shirt. Therefore , this statement is also correct .

(D) The argument is correct since all of the subsets contain grey slacks and no black slacks.

Hence , all the options A , B , C , D are correct and describes the subset .

IrinaK [193]

Answer:


Step-by-step explanation:

1. The given equation is:

\frac{3}{5}{\times}\frac{4}{5}

Multiplying both the terms, we get

\frac{12}{25}

Option A is correct.

2. The given equation is:

2\frac{1}{3}{\times}\frac{3}{4}

Converting the improper fraction into the mixed fraction,

\frac{7}{3}{\times}\frac{3}{4}

=\frac{7}{4}

Option C is correct.

3. The given equation is:

\frac{3}{16}{\times}\frac{4}{21}

Multiplying both the terms, we get

=\frac{1}{28}

4. The given equation is:

3\frac{8}{9}{\times}4\frac{4}{5}

Converting the improper fraction into the mixed fraction,

\frac{35}{9}{\times}\frac{24}{5}

=\frac{56}{3}

5. One package contains= 5\frac{1}{4}=\frac{21}{4} pounds of raisins.

4\frac{2}{3} packages contains=4\frac{2}{3}{\times}5\frac{1}{4} pounds of raisins.

=\frac{14}{3}{\times}\frac{21}{4}

=\frac{49}{2}

Therefore, the baker used \frac{49}{2} pounds of raisins.
