Answer:

It should be 5:10 or 5 people not wearing sneakers and 10 not wearing a blue shirt

Step-by-step explanation:

Well it quite simple 1st you have the total which is 40

next you look at the rest, 15 people wearing sneakers plus the 5 waering sneakers and blue shirt. now you have 15.

next you have 10 people wearing but shirts. if you add the numbers you have now you get this: 15+10=25.

Now that you have 25 you can just add numbers to get 25(in that case 10 and 5). whats how you get 5:10

hope this helps (barry_ary)

Answer:

B or 3.5 if you meant 1/2 as many small wreaths as medium wreaths

Step-by-step explanation:

(Keep in mind you wouldn't write 1x where I wrote it, but just x instead, I just wrote 1x to make it easier to understand)

You have 1x medium wreaths to start with.

You have twice as many large wreaths as medium wreaths.

1x ⋅ 2 = 2x

So you have 1x medium wreaths and 2x large wreaths.

Lastly, it says you have 1/2 as many small wreaths as medium wreaths.

1x ⋅ 1/2 = 1/2x

So you have

1x + 2x + 1/2x = 3 1/2x wreaths, which is answer B.

Let us denote by P the set of all people, by S the set of people who are single, by C the set of people who have children, by W

natita [175]

Solution :

Given :

The events are as follows :

P : Set of all the people

S : Set of people those who are single

C : Set of people having children

W : Set of women

M : Set of men

a). Now set of married women having children is given by :

$\left( (P-S)-M \right) \cap C$

And set of single women who do not have any children : (S -C) - M

Thus the set of women those who are either married and have children or they are single and they do not have any children is represented by :

$\left( (S-C)-M\right) \cup \left( ((P-S)-M) \cap C \right)$

b). Set of Married men : $\left( (P-S) \cap M$

Set of Married men : $\left( (P-S) \cap W$

Set of all possible married who are heterosexual couples, that is, all possible pairings of the married men and the married women is represented by :

$((P-S) \cap M) \cap ((P-S) \cap W )$

c). The number of all the possible married heterosexual couples will be represented by the cardinality of the above set, which represents the number of the elements in the set.

Thus the number of the married heterosexual couples is given by :

$n[((P-S) \cap M) \cap ((P-S) \cap W)]$

If f(x) = 5x + 40, what is f(x) when x = –5? –9 –8 7 15

Gnoma [55]

Hi,

$f(x)=5x+40\\\\f(-5)=5\times(-5)+40=-25+40=15\\f(-9)=5\times(-9)+40=-45+40=-5\\f(-8)=5\times(-8)+40=-40+40=0\\f(7)=5\times7+40=35+40=75\\f(15)=5\times15+40=75+40=115$
