Deanna's scores for a computer game are 18, 20, 22, 25, 12, and 20. lilly's scores are 20, 20, 21, 21, 16, and 16. who has the higher mean score? by how much?

Deanna has the higher mean score by .5

Step-by-step explanation: The important piece of information to remember here is that the mean is the average. In order to solve the question, the first thing that you need to do is calculate the average of each of their scores.

Deanna = 18+20+22+25+12+20 = 117

The mean = 117/6 = 19.5

Lilly = 20+20+21+21+16+16 = 114

The mean - 114/6 = 19

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
