Answer:

$P(Green\ and\ Green) = \frac{25}{144}$

Step-by-step explanation:

Given

$Green=5$

$Blue = 7$

Required

$P(Green\ and\ Green)$

This is calculated as:

$P(Green\ and\ Green) = P(Green) * P(Green)$

Since, it is a probability with replacement, we have:

$P(Green\ and\ Green) = \frac{Green}{Total} * \frac{Green}{Total}$

So, we have:

$P(Green\ and\ Green) = \frac{5}{12} * \frac{5}{12}$

$P(Green\ and\ Green) = \frac{25}{144}$

Rounded to the nearest hundredth, what is the positive solution to the quadratic equation 0 = 2x2 + 3x – 8?

zmey [24]

2x² + 3x -8 = 0

a = 2 , b = 3 , c = -8
So..
D = b²-4ac = 9 + 64 = 73

for bigger solution , use x = -b + √D / 2a
For smaller solution, use x = -b - √D / 2a

So
= -3 + √73 / 2. 2
= 1/4 (√73 -3)

Hopefully helpfull.. ^_^
