Much like sound bites of news​ stories, statistical studies are often reduced to​ one- or​ two-sentence "stat-bites." For the​st
Ira Lisetskai [31]

Answer:

Step-by-step explanation:

Given that According to a video streaming​ service, 48% of American couples are​ "cheaters", that is—they promise each other to watch a film​together, but one of them first watches it alone.

Here if this is binomial with two outcomes we can easily say that the other 52% couples go together movies.

But here there are not only two outcomes.

The other possibilities are:

i) Either both do not go to movies

ii) Both cheat and go to movies separately

Thus since there are not exactly two outcomes, we cannot say the other 52% go to movies together.

As much as say that 52% of couples are not cheating in this way.

How many different triangles can be constructed using angle measurements 81 52 and 47? I need the answer really fast and like ri
solniwko [45]
The options are:
A) exactly one triangle;
B) no triangles;
<span>C) more than one triangle.</span>

First thing, let's see if these angles can make a triangle:
(81 + 52 + 47) = 180

We know that the sum of the inner angles of a triangle must equal 180°, therefore yes, they can be angles of a triangle.

With only the measure of the angles and nothing about the sides, we can construct as many triangles as we want: try, indeed, to construct a triangle with given angles bus sides of your choice; then, double the sides. You will get a triangle that is twice the size, but the angles remained the same.

Hence, the correct answer is C) more than one triangle.
