A marble is drawn at random from a bag containing 2 blue

1 answer:

6 0

7/12
So we first need to add up all the marbles so there are 12 marbles to pick from so we know that there is 7 orange marbles and since there are only three colors and two of them we don’t want pick there is a 7/12 chance of getting a marble that isn’t yellow or blue and since we can’t simplify any further that’s the answer

The point P = (x, - 2/7) lies on the unit circle shown below. What is the value of x in simplest form?

miskamm [114]

Answer: $x = \frac{3\sqrt{5}}{7}\\\\$

Explanation:

The equation of the unit circle is $x^2+y^2 = 1\\\\$

Plug in y = -2/7 and solve for x

$x^2+y^2 = 1\\\\x^2+\left(-\frac{2}{7}\right) = 1\\\\x^2+\frac{4}{49} = 1\\\\x^2 = 1-\frac{4}{49}\\\\x^2 = \frac{49}{49}-\frac{4}{49}\\\\x^2 = \frac{45}{49}\\\\x = \sqrt{\frac{45}{49}} \ \ \text{ ... x is positive}\\\\x = \frac{\sqrt{45}}{\sqrt{49}}\\\\x = \frac{\sqrt{9*5}}{7}\\\\x = \frac{\sqrt{9}*\sqrt{5}}{7}\\\\x = \frac{3\sqrt{5}}{7}\\\\$
