Factorize 9/16 x2 + xy + 4/9 y2

miskamm [114]

$\frac{9}{16} x^2 + xy + \frac{4}{9} y^2 = (\frac{3}{4} x)^{2} + xy + (\frac{2}{3}y)^{2} = (\frac{3}{4} x)^{2} + 2* \frac{3}{4} x * \frac{2}{3}y + (\frac{2}{3}y)^{2}$ $= ( \frac{3}{4}x + \frac{2}{3} y)^{2}$

5) You randomly choose a marble from a jar. The jar contains 4 red

Dmitry [639]

the probability of the event choosing a yellow marble is 2/9 .

<u>Step-by-step explanation:</u>

Here we have , to choose a marble from a jar. The jar contains 4 red

marbles, 10 blue marbles, 7 green marbles, and 6 yellow marbles. We need to Find the probability of the event choosing a yellow marble . Let's find out:

According to question question we have following parameters as :

Red marbles = 4

Blue marbles =10

Green marbles = 7

Yellow marbles = 6

Now , Probability to chose a yellow marble is :

Favorable outcomes = 6(Number of yellow marbles )

Total outcomes = 4+10+7+6 = 27( Total marbles )

Hence ,

⇒ $Probability = \frac{6}{27}$

⇒ $Probability = \frac{2}{9}$

Therefore , the probability of the event choosing a yellow marble is 2/9 .
