The answer is 
x _ 2y = 2
<span>3x + y = 6     
</span>3x _ 6y = 6 (1
<span>3x + y = 6  (2
</span>(1 - (2
-7y=0, y=0, so x - 2.0=2 implies x=2

Answer:

x=2

Step-by-step explanation:

we have

x-2y=2 ------> equation A

3x+y=6 ------> equation B

Multiply by 2 equation B

2*(3x+y)=2*6 ------> 6x+2y=12 -----> equation C

Adds equation A and equation C

x-2y=2\\6x+2y=12\\--------\\x+6x=2+12\\7x=14\\x=2

Find the value of y

x-2y=2

2-2y=2

2y=0

y=0

Sophie [7]

Answer:

answer : 164 pounds

Step-by-step explanation:

total weight of five computers

163 x 5 = 815 pounds

the weight of the fifth one = total

weight - other four

815-155-160-165-171=164 pounds

. How do these two processes, finding the expected value of a discrete random variable and finding the dot product
kozerog [31]

Answer:

We can conclude that on this case we have identical processes but excersise 17 use another way to present the probability distribution and as we can see the expected value can be viewed as a dot product of two vectors with one vector containing the outcomes and the other the probabilities for each possible outcome.

Step-by-step explanation:

Assuming this previous info:

Exercise 17. Suppose that we convert the table on the previous page displaying the discrete distribution for the number of heads  occurring when two coins are flipped to two vectors.

The volume of the slice is 40 in³. The volume of the remaining cake would be 197.014 in³.

<h3>What is a regular hexagon?</h3>

A regular hexagon can be defined as a closed shape consisting of six equal sides and six equal angles.

Here we have two regular hexagons

one top small hexagon cake with a side of length = 3 in, height = 3 in

One big hexagon cake, side of length = 4 in, Height = 4 in

A slice cut such that it removes a side segment is equivalent to an equilateral triangle with a side

length = length of hexagon side

The length of the side of the removed equilateral triangle side

Top small cake slice triangle side = 3 in.

Area of surface of small slice = 1/2 x b x h = 1/2 x 3 x 3 x sin 60

                                                = 9√3/ 4

The volume of a small slice  

=  Area of surface small slice × Height of small cake

= 9√3/ 4  x 3

= 11. 69

Big cake slice triangle side = 4 in.

Area of the surface of big slice = 1/2 x 4 x 4 x sin 60

                                                    = 4√3

The volume of big slice =  Area of the surface of big slice × Height of big slice

= 16√3

= 28

The total volume of slice = Volume of small slice + Volume of big slice

Total volume of slice = 12 in³ +28 in³ = 40 in³

For the small cake,

the remaining volume = 5 x 11.69 = 58.45

For the big cake

the remaining volume = 5 x 27.71 = 138.56

Total volume remaining cake

= 58.45 in³ + 138.56 in³ = 197.014 in³

a = Length of side

h = Height of hexagon

The volume of each slice is,

= a^2 x h x √3/4

For the small cake, we have

a = 3 in.

h = 3 in.

The volume of small slice = a^2 x h x √3/4

                                   = 9 x 3 x √3/4

                                   = 27√3/4

For the big cake, we have

a = 4 in.

h = 4 in.

Volume of big slice =  a^2 x h x √3/4

                                = 16 √3

The total volume of slice = Volume of small slice + Volume of a big slice

Total volume of slice = 27√3/4 + 16 √3

The total volume of the slice = 39404 in³.
