the answer is c: .... 72+8w
Your answer is D. Hope this helps!
Let list the data in ascending order 100, 100, 105, 113, 129, 132, 146, 152, 176, 200
There are ten numbers so the thirtieth percentile would be the .3 * 10
= 3rd number, ordered from smallest to largest.
so the third number, the thirtieth percentile, is 105
{ x + 4y = 22 ( + x - x = 0 )
{ - x + 5y = 23
4y + 5y = 22 + 23
9y = 45
y =<u> 45 </u>
9
y = 5
x + 4y = 22
x + 4 . 5 = 22
x + 20 = 22
x = 22 - 20
x = 2
S = { 2 , 5 }
