Find the mode of the following data set.

a. 31
b. 3 and 4
c. 1

31

Step-by-step explanation:

the mode is the number that appears the most, in that case it would be 31. i also just did this in a quiz 2 seconds ago and was right.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
