Answer:

0.3

Step-by-step explanation:

Given: The odds of winning a contest are 3:7

To find: probability of winning the contest

Solution:

Probability refers to chances of occurrence of an event.

Odds are defined as (chances for success) : (chances against success)

Probability of winning = (chances for success) : (chances for success + chances against success)

As odds of winning a contest are 3:7,

(chances for success) : (chances against success) = 3:7

So,

Probability of winning the contest = $\frac{3}{3+7} =\frac{3}{10}=0.3$

$\frac{1}{8} \times \frac{2}{5} = \frac{1 \times 2}{8 \times 5} = \frac{2}{40} = \frac{2 \div 2}{40 \div 2} = \frac{1}{20}$
The answer is
$\frac{1}{20}$

I need help with the photo below.

PSYCHO15rus [73]

Here, 30/360 * 2πr = 10
1/12 * 2 * 3.14 * r = 10
r = 10*12 / 6.28
r = 19.11

Now, Area = 1/12 * 3.14 * (19.11)²
= 3.14/12 * 365.16
= 95.5 Ft²

In short, Your Answer would be Option C

Hope this helps!

AB = 10 in; AD = 6 in A= 30sqrt3 in2 30 in2 60 in2

Ratling [72]

Answer: 30

Step-by-step explanation:

If we were to draw diagonal BD, then we would create two congruent triangles, and we could find the area of each using the formula $A=\frac{1}{2} ab \sin C$ .

However, since there are two triangles, we can double this, giving us $A=ab \sin C$ .

So, the area is $A=(10)(6)(\sin 30^{\circ})=\boxed{30}$
