Answer:

y=-4x-2

Step-by-step explanation:

linear function, y = mx+c

the y intercept of the graph,c, is -2

thus y = mx - 2

substitute a point on the graph into the equation, (2,-1)

2 = m(-1) -2

m = - 4

thus equation of graph is y = -4x-2

A bag contains eight yellow marbles, nine green marbles, three purple marbles, and five red marbles. Two marbles are chosen from

Kryger [21]

Answer:

The expression would give the probability that one marble is yellow and the other marble is red is,

$P(Y\cdot R\ And\ R\cdot Y)=P(Y)P(R)+P(R)P(Y)$

Step-by-step explanation:

A bag contains eight yellow marbles, nine green marbles, three purple marbles, and five red marbles. So in total there are 25 marbles.

Hence,

Probability of getting yellow ball = $P(Y)=\dfrac{8}{25}$

Probability of getting red ball = $P(R)=\dfrac{5}{25}$

Probability that one marble is yellow and the other marble is red is,

$P(Y\cdot R\ And\ R\cdot Y)=P(Y)P(R)+P(R)P(Y)=\dfrac{8}{25}\cdot \dfrac{5}{25}+\dfrac{5}{25}\cdot \dfrac{8}{25}=0.128$

Plz help me solve it the question is below

AlladinOne [14]

Answer:

$\frac{1024}{2025}$

Step-by-step explanation:

$\frac{3}{4}^{-4} = \frac{1}{\frac{3}{4}^{4} }$

(3/4)^4 = 81/256

1 ÷ 81/256 = 256/81

So;

$\frac{256}{81} * \frac{4}{9} = \frac{1024}{729}$

$\frac{1024}{729} / n = \frac{1}{9/25}$

$\frac{1024}{729n} = \frac{25}{9} \\\\n = \frac{1024 *9 }{25 * 729} = \frac{1024}{2025}$
