The scatter diagram shows information about 10 cars. The 10 cars are the same type and make. Another car is 4 years old and has been valued at £2600.
A)Show this information on the graph.

B) describe the relationship between the age and the value of the cars.

A car of the same type and make is 3 1/2 years old
C) estimate the value of the car

a) you need to plot a cross on the graph (with the pencil) in the right place:

(x-axis: 4, y-axis: 2600)

b) the older the car is, the lower its value. there is a negative correlation between the cars age and its value.

c) you need to draw a line of best fit on the graph. where the line is at 3 1/2 years, that is its estimated value. (my guess is around £3000)

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
