Probability of pulling a green marble out of a bag of coloured marble is 2:5 if you were to pull coloured marbles out of the bag

Slav-nsk [51]

Answer: 171 green marbles

Step-by-step explanation: There are 7 total marbles so 100/7 equals 14.28

Then there is a 2 out of 7 total tries so 14.28 * 2 equals 28.57% chance to get a green marble.

600 * 0.2857 = 171.41 marbles but you cant get half a marble so 171 green marbles.

(PLEASE HELP 15 POINTS I HAVE 7 MINS) explain your awnser what are the x- and the y-interceptions of 3x - 2y = 18

S_A_V [24]

The given equation is

$3x-2y=18$

x intercept

To find the x intercept, we have to plug 0 for y and solve for x.That is

$3x-2(0)=18
\\
3x=18
\\
x=6$

So x intercept is (6,0) .

y intercept

To find the y intercept , we have to plug 0 for x and solve for y. That is

$3(0)-2y=18
\\
-2y=18
\\
y=-9$

So the y intercept is (0,-9) .

The expression cosine of pi over 2 times cosine of pi over 3 plus sine of pi over 2 times sine of pi over 3 can be rewritten as

9966 [12]

Solution:

Given;

$\cos\frac{\pi}{2}\cos\frac{\pi}{3}+\sin\frac{\pi}{2}\sin\frac{\pi}{3}$

Using the identities;

Thus;

$\begin{gathered} \cos\frac{\pi}{2}\cos\frac{\pi}{3}+\sin\frac{\pi}{2}\sin\frac{\pi}{3}=\cos(\frac{\pi}{2}-\frac{\pi}{3}) \\ \\ \cos\frac{\pi}{2}\cos\frac{\pi}{3}+\sin\frac{\pi}{2}\sin\frac{\pi}{3}=\cos(\frac{\pi}{6}) \end{gathered}$

CORRECT OPTION: A
