Answer:

Step-by-step explanation:

Because 17 is greater than 5 + 9.

To form a triangle, no side can be equal or greater than the sum of the other 2 sides.

The notation f:S→T denotes that f is a function, also called a map , defined on all of a set S and whose outputs lie in a set T

AnnyKZ [126]

Answer:

There are many. Two examples are

$f(x) = x, \\f(x) = x^3$

Step-by-step explanation:

There are many examples. The simplest is

1 -

$f(x) = x$

It is trivial that

$\text{if \,\,\,\,} f(x) = f(y) \,\,\,\,\,\text{then} \,\,\,\,\, x=y$

2 -

$f(x) = x^3$

That function is injective as well.

$\text{if \,\,\,\,} x^3 = y^3 \,\,\,\,\,\text{then} \,\,\,\,\, x=y$

An example of a function that is NOT injective is

$f(x) = x^2$

Notice that

$f(-2) = (-2)^2 = 2^2 = 4$

Suppose that the probabilities that an answer can be found on Google is .95, on Answers is .92, and on both Web sites is .874. A

Assoli18 [71]

Answer:

The correct option is

a) Yes, because (0.95)(0.92) = 0.874

Step-by-step explanation:

An event is independent if the following condition is satisfied

$P(A\bigcap B)= P(A)P(B)$

Therefore, since the the probability that the answer can be found in Google = 0.95 and the probability that the answer can be found in Answers = 0.92

The probability that the answer can be found on both websites,

$P(A\bigcap B)$ = 0.874

We check, P(A) × P(B) = 0.95×0.92 = 0.874 = $P(A\bigcap B)$ = 0.874

Therefore, the possibilities of finding the event on the two websites is independent.
