Answer:

or

Step-by-step explanation:
The expression
can be simplified by first writing the fraction under one single radical instead of two.

5/15 simplifies because both share the same factor 5.
It becomes 
This can simplify further by breaking apart the radical.

A radical cannot be left in the denominator, so rationalize it by multiplying by √3 to numerator and denominator.

Joint Frequency because of the fact that it "joins" one number from the column(up and down) and one from the row(side-by-side), hence the two-way table.
They take about 5,000 to 10,000 steps each day.

I had to look for the figure and here is my answer:
Given the circle attached to this question, the area of the sector AOB is the 60 of the fractional part of the area of the circle O. Since the whole circle is 360, this would be 60/360. To simplify this, we would arrive to the final answer of 1/6. Hope this helps.
