What is the area of the red region?

Mathematics
1 answer:
Nitella [24]3 years ago
3 0

Answer:

≈ 57.13cm^{2}

Step-by-step explanation:

Area of Circle:

A = π r^{2}

π (4)^{2}

π (16)

≈ 50.27cm^{2}

Area of Square:

A = l(w)

8(8) = 64 cm^{2}

Area of each corner:

64 - 50.27 = 13.73cm^{2}

13.73 ÷ 4 ≈ 3.43cm^{2}

Area of Red:

50.27 + (3.43(2)) ≈ 57.13cm^{2}

You throw two four-sided dice. Let the random variable X represent the maximum value of the two dice. Compute E(X). Round your a
Troyanec [42]

Answer:

E(X)=3.125

Step-by-step explanation:

We are given that two four sided dice.

Then , the sample space

{(1,1),(1,2),(1,3),(1,4),(2,1),(2,2),(2,3),(2,4),(3,1),(3,2),(3,3),(3,4),(4,1),(4,2),(4,3),(4,4)}

Total number of outcomes=16

Let the random variable X represent the maximum value of the two dice

Outcomes                            X                                 P(X)

(1,1)                                          1                                 1/16

(1,2),(2,1),(2,2)                                   2                        3/16

(1,3),(2,3),(3,1),(3,2),(3,3)                    3                           5/16  

(1,4),(3,4) ,(2,4),(4,1),(4,2),(4,3),(4,4)    4                            7/16

Using the probability formula

P(E)=\frac{Favorable\;outcomes}{Total\;number\;of\;outcomes}

Now,

E(X)=\sum_{i=1}^{n}x_iP(x_i)

E(x)=1(1/16)+2(3/16)+3(5/16)+4(7/16)

E(x)=\frac{1+6+15+28}{16}

E(x)=\frac{50}{16}=3.125
