according to the video, how does \mainstream culture\ relate to a societys dominant values and norms?
mainstream culture changes every decade based on trends in consumer spending and the preferences of the largest demographic cohort.
mainstream culture is determined through democratic voting processes where citizens collectively decide which traditions should be considered normal.
mainstream culture represents the cultural patterns and practices that are most widely accepted and reflect the values of the societys most powerful groups.
mainstream culture consists exclusively of practices that have existed for at least three generations and have been formally codified into law.

Explanation:

Mainstream culture is defined as the shared cultural patterns, values, and norms that are most widely accepted within a society, and these typically align with the values and influence of the society's most powerful groups.

Answer:

Mainstream culture represents the cultural patterns and practices that are most widely accepted and reflect the values of the society's most powerful groups.
