We can analyze each of the statements. Responses of tourist who wish to visit these beaches: this is a biased sample, because they already want to go there so they have a positive opinion which may o may not be a direct perception. Responses from government officials of the countries where the beaches are located: not reliable because they have an interest to promote tourism toward their countries. Responses from tourists who have visited the beaches: this seems an appropiate group because they are the persons who have a real experience as tourist of those beaches and shoulb be more objective that the others. Responses from you friendes and family: hard to believe that they know most of the best beaches of the world to give a response bases on facts. <span>Then, the answer is the option Responses from tourists who have visited the beaches.</span>

Ven Diagrams with union and intersection problems shading in diagram
Anika [276]

Answer:

4 types of questions one will be to read, 2nd will be to subtract, one will be to add, the next will be to find missing numbers each are expressed below.

Step-by-step explanation:

This is a two-circle Venn diagram. The 1st circle is A, and the 2nd circle is B. The complete Venn diagram represents the union of A and B, or A ∪ B.

Just intersect is A ∩ B

Just intersect B ∩ A

A∩B=   A∩B={2}  differs significantly from below.

A  small ∁

 (sometimes denoted as ~A or ¬A)

is pronounced as: "A complement" (or "not A", for the other notations)

means: the new set gets everything that is in the universe but is outside of A; it's okay if the element is in B, just so long as it is not also in A

in terms of the elements: {1, 2, 3, 4} – {1, 2}

my answer:  = A ∁ ={3,4}

A – B (or A \ B)in terms of the elements: {1, 2} – {2, 3}

A – B = {1}

A∪B)=¬(A∪B)in terms of the elements: = {1, 2, 3, 4} – {2}

in terms of the elements: {1, 2, 3, 4} – ({1, 2} ∪ {2, 3}) = {1, 2, 3, 4} – {1, 2, 3}

(4) elements here are just the remainder my answer: my answer:(A∪B)={4}

8% of a number is 20
Gnoma [55]
To find what the number is, we need to set up proportional fractions.
Currently, we have 8% of a number is 20.
To set up our fractions, put 100% under 8% as a fraction first.

It should look like this: 8/100 (hint: per-cent means per-hundred).

Now, we have 20 out of a number, x. This is because we are claiming that 20 is 8% of a number (if we just reword the question without changing the concept).
It should look like this: 20/x.

Our proportional fractions are:
20/x = 8/100.

To solve for this, we need to cross-multiply the denominator of 8/100 (bottom number, 100) with the numerator of 20/x (top number, 20).

This product equation should look like this:
20 x 100 (when simplified, we get 2000).

Now, we need to cross multiply the numerator of 8/100 (top number, 8) with the denominator of 20/x (bottom number, x).

This product equation should look like this:
8x.

Now that we've cross-multiplied, set our two products as an equation.

8x = 2000.

To solve for x, divide both sides by 8 (remember, what you do to one side of an equation, you must do it to the other).

8x / 8 = x
2000 / 8 = 250.

x = 250

Your final answer is:

8% of 250 is 20.

I hope this helps!
