D a quadrilateral with one pair of parallel sides
10.5 is the standard deviation for the data set to the nearest tenth hope this helps;)
Answer:
1.625
Step-by-step explanation:
First we need to find the mean of this data set
29+32+33+28+30+30+29+33=244
Then we divide 244 by the amount of numbers in the set
244/8=30.5
Then we need to find the deviation of each number
29 | 32 | 33 | 28 | 30 | 30 | 29 | 33
1.5 | 1.5 | 2.5 | 2.5 | 0.5 | 0.5 | 1.5 | 2.5
Then we take the mean from this set of data
1.5+1.5+2.5+2.5+0.5+0.5+1.5+2.5=13
Then divide
13/8=1.625
I hope this helps :)
