Let A = {\bullet ,\square, \bigotimes} and B = {\square,\ominus, \bullet}.
lisov135 [29]

(a) With <em>A</em> = {•, □, ⊗} and <em>B</em> = {□, ⊖, •}, we have

<em>A</em> × <em>B</em> = {(•, □), (•, ⊖), (•, •), (□, □), (□, ⊖), (□, •), (⊗, □), (⊗, ⊖), (⊗, •)}

and

<em>B</em> × <em>A</em> = {(□, •), (□, □), (□, ⊗), (⊖, •), (⊖, □), (⊖, ⊗), (•, •), (•, □), (•, ⊗)}

(b) The intersection of the two sets above is

(<em>A</em> × <em>B</em>) ∩ (<em>B</em> × <em>A</em>) = {(•, •), (•, □), (□, •), (□, □)}

Not sure what µ is supposed to represent, but I suppose you meant to again write × as in the Cartesian product. By definition, for any two sets <em>A</em> and <em>B</em>, we have

<em>A</em> × <em>B</em> = {(<em>a</em>, <em>b</em>) | <em>a</em> ∈ <em>A</em> and <em>b</em> ∈ <em>B</em>}

Then

(<em>A</em> × <em>B</em>) ∩ (<em>B</em> × <em>A</em>) = {(<em>a</em>, <em>b</em>) | <em>a</em> ∈ <em>A</em> ∩ <em>B</em> and <em>b</em> ∈ <em>A</em> ∩ <em>B</em>}

In the product found above, notice that • and □ are both elements of <em>A</em> and <em>B</em>, while ⊗ and ⊖ are exclusive to either set.

Please answer In(5x-3)=4
Goshia [24]

Answer:

\huge\boxed{Answer\hookleftarrow}

(5x - 3) = 4 \\ 5x - 3 = 4 \\ 5x = 4 + 3 \\ 5x = 7 \\ x =  \frac{7}{5}  \\ x = 1.4

<h3>⎆ The answer will be, <u>x = 7/5 (in fraction form) & x = 1.4 (in standard form)</u><u>.</u></h3>

Zielflug [23.3K]
Answer:  The mode is: 3 .  The range is:  6 .
___________________________________
Explanation:
___________________________________
  It would be best to list this values in the data set given, from least to greatest:
________________________________________________
  { 3, 3, 3, 3, 4, 5, 5, 6, 9 } .
________________________________________________
  The mode is the number that occurs most frequently in the data set, which is: "3".
_________________________________________________________
{The number, "3", occurs FOUR (4) times.  The number, "4", occurs ONE (1) time.  The number, "5", occurs TWO (2) times.  The number, "6", occurs ONE (1) time.  The number, "9", occurs ONE (1) time.}.
___________________________________________________
The range is calculated from subtracting the LOWEST value in the data set FROM the HIGHEST value in the data set.
____________________________________________________
 The lowest values in the data set is: "3" .
 
 The highest value in the data set is: "9" .
________________________________________________
 To calculate the range:  9 <span>− 3  = 6 .  The range is:  "6".
</span>________________________________________________
  Answer:  The mode is:  3 .  The range is:  6 .

You start at (5, 3). You move down 3 units and left 6 units. Where do you end?
raketka [301]

Answer:

(-1, 0)

Step-by-step explanation:

5 is the x value which is left and right, so you said u move left 6 units. Since the 5 is positive and left is negative; 5-6= -1. 3 is the y value which is up and down (vertical), so you said u move down 3 units, since the 3 is positive, when you move down that is negative; so 3-3=0.
