There are 2 formulas for Circumference in common use.  One, which is more useful here, is C = pi d, where d is the diameter.  So, the C here is pi times 20 cm.
The other formula is C =2 pi r.  This makes sense, since 2r=d.

What is the value of the 30th percentile for the data set 6283, 5700, 6381, 6274, 5700, 5896, 5972, 6075, 5993, 5581?
sineoko [7]

To solve this problem, we should remember that the percentile rank of a single value is the rank of that value in the series of data set when that data set is arranged in ascending order.

Therefore arranging the data set, gives the sequence:

5581, 5700, 5700, 5896, 5972, 5993, 6075, 6274, 6283, 6381

<span>Since we are to find the 30th percentile (30 %) and there are a total of 10 values, therefore the 30th percentile is:</span>

10 * 30% = 3

<span>This means we look for the 3rd number in the ordered sequence.</span>

<span>
</span>

<span>Answer: 5700 is the 30th percentile of the series</span>

May I please receive help?

Answer:

9.2 ft

Step-by-step explanation:

The shape is a triangle, the 11 ft is your hypotenuse

You need to use the Pythagorean Theorem!

a^2 + b^2 = c^2 (solve for a, the missing length that they ask for)

so --->

a^2 + (6^2) = 11^2

      a^2 + 36 = 121

             ~subtract 36 to the right side~

               a^2 = 85

now find the square root of 85:

               a = 9.21954

        round it to the nearest tenth:

                   a = 9.2

final answer: 9.2 ft

hope this helpsss
