Amanda surveyed 20 juniors and seniors at delamar high school to find the number of hours per week they spend working at part-time jobs. Her results are shown below. Look at picture

The range of hours worked is the same for juniors and seniors

Step-by-step explanation:

Here, we are interested in selecting which of the options are true

Now the best way to answer this is to look at the options and check for the most probable answer

Let’s look at the option that contains ranges

Range means the difference between the lowest and the highest value

In both cases of data, the lowest value is 0 while the highest is 20

So the range in both cases is 20-0 = 20

This makes the option true

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
