On a single roll of two number cubes, what is the probability of rolling doubles given that the sum is 6
dexar [7]

Answer:

1/6

Step-by-step explanation:

We can make a Punnett square to find number of favourable outcome

so

            cube1

         +

cube2    1          2          3        4          5         6

1            2         3           4        5          6        7      

2            3         4           5        6          7         8    

3            4          5         6        7         8         9

4           5          6          7         8         9         10

5         6           7          8         9        10         11

6           7           8          9         10        11         12

The probability of rolling doubles given that the sum is 6

<h3> favourable outcome / number of outcome</h3>

 6 / 36

  1 / 6

Convert the rectangular coordinates (4√3,−4) to polar form. Let r&gt;0 and 0≤θ&lt;2π.
spayn [35]

Answer:

(8,150)

Step-by-step explanation:

Polar form is in,

(r,theta).

To find r, apply pythagorean theorem using both coordinates to find r.

(4 \sqrt{3} ) {}^{2}  + ( - 4 {}^{2} ) =  {r}^{2}

48 + 16 =  {r}^{2}

r = 8

To find theta, since we know the opposite and adjacent side, apply the tangent function.

\tan(x)  =  \frac{ - 4}{4 \sqrt{3} }

Apply inverse tan function

\tan {}^{ - 1} ( \frac{ - 4}{4 \sqrt{3} } )  =  - 30

Since the degrees have to be in between 0 and 360. Add 180 to -30.

- 30 + 180 = 150

So the answer is

(8,150).
