17 multiplied by 8 is 136.
Just count how many times a given age appears in the data. If my eyes aren't deceiving me, I count
• 26: 3
• 27: 5
• 28: 5
• 29: 5
• 30: 2
• 31: 1
• 33: 4
Then the second most frequent age in the data is 33, and the least frequent is 31.
Since both objects are assumed to have the same volume, matching the formulas we'll get:
π

h =

π

h
Having both <span>π and h at both sides of the equation, we can ignore them, so:
</span><span>

=


</span>
And clearing R, according to the equation rules, we'll get:
= R
Answer:
BC ≈ 1.71
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos70° =
=
= 
Multiply both sides by 5
5 × cos70° = BC , thus
BC ≈ 1.71 ( to the nearest hundredth )
