Answer:
Q₂ = 78
Step-by-step explanation:
Q₂ is the median of the data set.
The median is the middle value of the data arranged in ascending order.
If there is no exact middle value then it is the average of the values either side of the middle.
48, 64, 66, 70, 72, 84, 86, 90, 92, 94 ← in ascending order
↑ middle

SOLUTION
From the question, we are told that y varies inversely as x
This is mathematically written as
Now, we will remove the proportionality sign and replace it with equal to sign =
If we do this, we will intoduce a constant k
So we have the formula
We will substitute the values of x for 10 and y for 8 into the formula to get k, we have
Now, we will substitute k for 80 back into the formula to get the inverse function, we have
Hence the answer is option C

ANSWER
• Circumference: 18.84 ft
,• Area: 28.26 ft²
EXPLANATION
The circumference of a circle of radius r is,
In this case, the radius is r = 3 ft and we have to use 3.14 for π,
Hence, the circumference of this circle is 18.84 feet.
The area of a circle of radius r is,
In this case, r = 3 ft and π = 3.14,
Hence, the area of this circle is 28.26 square feet.
