you cannot get that answer.... when you divide. Put the number into a fraction first so, it makes it easier to see what you are doing. So,
.Now simplify the cross off the zero from the top and the bottom to get
. So,
will give you 0.83333333333...3.
First, I'd like to say that this question is flawed because the diameter of the spool changes as you pull the line out. Some would argue it's negligible I suppose.
At any rate, assuming there's a magic spool where the diameter doesn't change, let's find the cicumference so we can find the length of one wrap around the spool.
circumference = 2*pi*r = 2 * pi * 4cm = about 25.133 cm
Now if it turns 16 times we'll have 16 times the circumference.
16 * (25.133 cm)
= 402.128 cm
Answers:
Mean - 85.2
Median - 85
Mode - 85
Explanation:
Mean - 77+85+85+86+93=426/5 (the amount of data points given) = 85.2
Median - Organize the data points from least to greatest and eliminate the outermost numbers two at a time (one from both side) until you’re left with one.
Mode - The number that appears the most often in a given data set
