Convert 2.3 * 10^-4 and 4.6 * 10^-5 into decimals, obtain your solution; and finally, convert that number into scientific notation.

2.3 * (10^-4) = .00023
6 * 10^-5 = .00006

.00023 - .00006 = .00017

and finally, .00017 = 1.7 * 10^-4

Your answer is 1.7*10^-4

Hope this helps!

a box contains 4 yellow, 5 green and 3 blue balls. find the probability of obtaining a yellow ball in a single random draw.

Alex

Notice that the box has a total os 4 + 5 + 3 = 12 balls, since there are 4 that are yellow, then, the probability to randomly obtaining a yellow ball in a single draw is:

$P(Yellow)=\frac{\text{ number of yellow balls}}{\text{total number of balls}}=\frac{4}{12}=0.33$

therefore, the probability is 0.33 = 33%

Which, if any, of

You need to convert the cartesian coordinates to polar: This means we need to go from (x, y) --> (r, angle)

We can covert, using the following formulas:

Find r:

$(x, y) --> (2, 2\sqrt{3})$

$r^2 = \sqrt{x^2 + y^2}$

$r^2 = \sqrt{2^2 + (2\sqrt{3})^2}$

r = 4

Now, find our angle:

Use the inverse of tan

$\tan^{-1} \frac{2}{2\sqrt{3}} = 30\deg$

Turn 30 degrees to radian

$\frac{\pi}{180} * 30 = \frac{1}{6}\pi$

Answer = $(4, \frac{1}{6}\pi)$ = C
