3. Pop CDs = 100 Jazz CDs = 40 Classical CDs = 30 Rock CDs = 60  100 + 40 + 30 + 60 = 230

Answer 2

Answer:

a) There is no mode.

b) 30 CDs

c) 230 CDs

Explanation:

a) No number of CDs is repeated, so there is no mode.

b) Number of Rock CDs = 60 (20 × 3)

Number of Classical CDs= 30 (20 × 1.5)

$60 - 30 = 30 CDs$

c) Pop = 100 CDs (20 × 5)

Jazz = 40 CDs (20 × 2)

Classical = 30 CDs (20 × 1.5)

Rock = 60 CDs (20 × 3)

$100 + 40 + 30 + 60 = 230 CDs$
