Answer:
18.84 feet
Step-by-step explanation:
The circumference of a circle can be found using:
c=π*d
The radius is given, but we have to find diameter. The diameter is twice the radius, or
d=2r
The radius is 3 feet. Substitute 3 in for r.
d=2*3
d=6
The diameter is 6 feet.
Now we have the diameter. We can substitute 6 in for d in the circumference formula. We can also substitute 3.14 in for pi.
c=π*d
c=3.14*6
c=18.84
The circumference is <u>18.84 feet</u>
Hope that “3/4 x 2/4” is what you are looking for. You have to multiply the numerator and the denominator of the second term by 2.
Measures of variation: <span> ways to describe measures of central tendency for a data.
<em>
</em><em>the most common measure of variation is range, so in this case, the smallest number is 1, and the largest is 17. This means the range is 16.
</em>
Interquartile Range:
<em>Lower q: {1, 2, 4}
</em><em>Upper q: {8, 12, 17}
</em>Here you have to subtract 12 from 2, which gives you 10.
Mean absolute deviation:
Alright, let's first find the mean...
(1+2+4+5+8+12+17)
---------------------------= 7
7
What is the distance of each number from 7?
1: 6 units
2: 5 units
4: 3 units
5: 2 units
8: 1 unit
12: 5 units
17: 10 units
After adding all of these together, and dividing by 7, you will get...
<em>4.571428 </em></span>≈ <em>4.6 or 5.
