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:
Tim has 75 pencils and 25 pens
Step-by-step explanation:
To solve this create a system of equations. To do so, first create an equation for the total number of utensils that he has. Let x equal the number of pencils and y equal the number of pens.
x+ y = 100
Now make one for the comparison of the two and solve for the constant.
x = 3y
x - 3y = 0
Now to solve the system, multiply the second equation by -1 and add them together.
x + y = 100
-x + 3y = 100
-----------------
4y = 100
y = 25
Now that we have the number of pens, find the number of pencils using an equation.
x + y = 100
x + 25 = 100
x = 75

Answers: x = 8 and x = -8</h3>
========================================================
Work Shown:
x^2 + 15 = 79
x^2 = 79-15
x^2 = 64
x = sqrt(64) or x = -sqrt(64)
x = 8 or x = -8
As the steps above show, we first subtract 15 from both sides. Then we apply the square root to get the two results. Don't forget about the plus minus.
