Answer:

yes, its linear and proportional .

Step-by-step explanation:

In mathematics, two varying quantities are said to be in a relation of proportionality, if they are multiplicatively connected to a constant, that is, when either their ratio or their product yields a constant. The value of this constant is called the coefficient of proportionality or proportionality constant.

you just have to graph it .

hope i helped :) !!! brainliest ??

Jalen is buying a new car. Model: compact, luxury, sport Transmisión: automatic, manual Color: red, blue, black, yellow Jalen de

Gwar [14]

<h3>Jalen can decide a yellow car in 6 possible ways.</h3>

Step-by-step explanation:

The total number of options in Model = 3

{Compact, Luxury, Sport}

The total number of options in Transmission = 2

{Automatic, Manual }

The total number of options in color = 4

{Red, Blue, Black, Yellow }

The color he has decided is <u>YELLOW.</u>

<u></u>

So, the total number of options in model is 3 and transmission is 2.

⇒ The number of ways that can be decided = 3 x 2 = 6 ways

So Jalen can decide a yellow car in 6 possible ways.

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.
