Answer:

(A) 6/20 = x/2000

Step-by-step explanation:

To complete your questions, the missing parts are shown below

                   Sample 1                  Sample 2        total

Country            5                               3                 8  

Pop                  4                                3                 7

Classical          3                                5                 8

Jazz                 2                                4                  6

Rock                6                                5                11

Total                20                               20             40

The proportion that would predict the number of jazz songs that Mr. McElroy has stored on his MP3 player is given by 6/20

Hence, our required proportion would be

6/20 =x/2000

We cross multiply  

20x = 2000 x 6

20x = 12000

Divide both sides by 20

X = 12000/20

X = 600

Hence, our required proportion would be

6/20 = x/2000

Please help!!
damaskus [11]

Answer:

6a) 1

6b) 11

7a) 4

7b) 10

8a) 6

8b) 14

9a) 11

9b) 13

Step-by-step explanation:

In order to make a triangle, we need to follow this property:

a <= b + c

(Known as "triangle inequality")

Where 'a' is the bigger side and 'b' and 'c' are the other two sides.

So, using this property, we can solve the following problems:

6a) Maximum side will be 6:

6 <= 5 + c

c = 1

6b) Minimum sides will be 5 and 6:

a <= 5 + 6

a = 11

7a) Maximum side will be 7:

7 <= 3 + c

c = 4

7b) Minimum sides will be 3 and 7:

a <= 3 + 7

a = 10

8a) Maximum side will be 10:

10 <= 4 + c

c = 6

8b) Minimum sides will be 4 and 10:

a <= 4 + 10

a = 14

9a) Maximum side will be 12:

12 <= 1 + c

c = 11

9b) Minimum sides will be 1 and 12:

a <= 1 + 12

a = 13

Find the next two numbers in the pattern.
RSB [31]
Let u_n be the n' th term of the sequence.


u_1=7\\\\u_2=-28=-7\cdot4\\\\u_3=112=7 \cdot4^2\\\\u_4=-448=-7\cdot 64=-7\cdot 4^3\\\\u_5=1792=7 \cdot 4^4

thus it is clear that:

u_6=-7 \cdot 4^5=7168\\\\u_7=7\cdot 4^6=28,672
