Select all of the following that are ordered pairs of the given function.

Rainbow [258]

If you plug x-coordinate in x then solve for y, and what you get for y matches t-coordinate, then this is correct ordered pair.

For explain: (-2, -1)

Plug in x-coordinate; f(-2) = 3 - 2(-2) = 3+4 = 7

-1 isn't equals to 7, so (-2, -1) is not right order pair.

Doing that thing and you should get:

Answer: (-1, 5), (0, 3), (2, -1)

Please helpppp it has to do with P(A U B)

Katyanochek1 [597]

$P(A)=0.5$ , $P(B)=0.6$ , $P(A\cup B)=0.8$

We find the probability of intersection using the inclusion/exclusion principle:

$P(A\cap B)=P(A)+P(B)-P(A\cup B)=0.3$

By definition of conditional probability,

$P(A\mid B)=\dfrac{P(A\cap B)}{P(B)}=\dfrac{0.3}{0.6}=0.5$

For $A$ and $B$ to be independent, we must have

$P(A\cap B)=P(A)\cdot P(B)$

in which case we have $0.3=0.5\cdot0.6$ , which is true, so $A$ and $B$ are indeed independent.

Or, to establish independence another way, in terms of conditional probability, we must have

$P(A\mid B)\cdot P(B)=P(A)\cdot P(B)\implies P(A\mid B)=P(A)$

which is also true.

Figure ABCD is a trapezoid. Find

Rudiy27

Answer:

x = 3

Step-by-step explanation:

The midsegment is half the sum of the parallel bases, that is

$\frac{1}{2}$ (3x + 3 + 4x + 2) = 13

$\frac{1}{2}$ (7x + 5) = 13 ( multiply both sides by 2 )

7x + 5 = 26 ( subtract 5 from both sides )

7x = 21 ( divide both sides by 7 )

x = 3
