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
Answer:36cm
Step-by-step explanation:
If the radius is HALF of the diameter, then the expression would be 1/2r=d or d/2=r.

Answer:
Required output = 14
Step-by-step explanation:
Sum of the input 3 and 4 = 3 + 4
Twice the sum means two times.
So, to find twice the sum of the input 3 and 4, we need to multiply the sum by 2.
2(3 + 4)
Perform the addition inside the parentheses.
2(3 + 4) = 2(7)
Now, multiply.
2(3 + 4) = 14
Hence, required output = 14
