Serggg [28]

Answer:

E(x) = 21834

Step-by-step explanation:

Given

The above data

Required

Determine the expected value E(x)

E(x) is calculated as thus;

E(x) = \sum xf(x)

Where f(x) represents the total sale of each outcome;

For A:

f(x) = 295 *34

f(x) = 10030

For B:

f(x) =510 *49

f(x) =24990

For C:

f(x) = 790 *59

f(x) = 46610

Hence, E(x):

E(x) = 0.5 * 10030 + 0.30 * 24990 + 0.20 * 46610

E(x) = 21834

The base of a regular pyramid is a hexagon.
Leona [35]

ANSWER

96 \sqrt{3}  {cm}^{2}

EXPLANATION

The area of a regular polygon is

Area= \frac{1}{2} ap

where 'a' is the apothem of the polygon and 'p' is the perimeter of the polygon.

From the diagram,

\sin(60)  =  \frac{a}{8}

a=8sin(60)

a = 4 \sqrt{3}

\cos(60)  =  \frac{l}{8}

l = 8 \cos(60)

l = 4

The length of one side of the hexagon is 2×4=8.

The perimeter of the hexagon is

p=6×8=48

The area of the hexagon is

=  \frac{1}{2}  \times 4 \sqrt{3}  \times 48

= 96 \sqrt{3}  {cm}^{2}

What do i do ???????
slamgirl [31]

Answer:

move each point of the triangle 5 units to the right and one unit up.

G is at -3,-1

-3+5 = 2

-1+1 = 0

2,0 is the coordinates of G' or the new G

T is at -1,-1

-1+5 = 4

-1+1 = 0

4,0 is the coordinates of T' or the new T

Last of all, B is at -3,-5

-3+5 = 2

-5+1 = -4

2,-4 is the coordinates of the B' or the new B.

12!/3!13! What does this mean?
AfilCa [17]
12! = 12x11x10x9x8x7x6x5x4x3x2x1 =479,001,600

3! = 3x2x1 =6
13! = 6,227,020,800

6,227,020,800 x 6 = 37,362,124,800

479,001,600/37,362,124,800=0.0128
