Answer: The data are quantitative because they consist of counts or measurements.
Step-by-step explanation:
The definition of quantitative data says that if we can count or measure some thing in our data such as number of apples on each bag , length, width, etc then the data is said to be quantitative.
On the other hand in qualitative data we can obverse characteristics and features but can't be counted or measured such as honesty , color, tastes etc.
Given : In studying different societies, an archaeologist measures head circumferences of skulls.
Since here we are measuring circumferences of skulls, therefor it comes under quantitative data.
Hence, the correct answer is : The data are quantitative because they consist of counts or measurements.

Answer:
Approximately 7.8 units
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
From the graph, we can see that A is (0,0). Let's let this be x₁ and y₁.
B is (-5,6). Let's let this be x₂ and y₂. So, substitute:
Simplify:
Square:
Add:
Take the square root. Use a calculator:
So, the distance between them is about 7.8 units.
And we're done!
The diagram included should explain this.
