Set up a ratio as a fraction:
_______________________________________________________
8/3 = 320/x ;
_______________________________________________________
Cross-multiply:
_____________________________________________________
8x = 3 * 320 ;
8x = 960 ;
Divide each side of the equation by "8" ;
to isolate "x" on one side of the equation ; and to solve for "x" ;
______________________________________________________
8x / 8 = 960 / 8 ;
to get: x = 120 .
The answer is: [A]: " 120 ft² " .

Let us calculate the median; the 6th observation is 20, so it is 20. We need the 6th observation so that out of the 11 observations we have 5 above the median and 5 below (or equal). We also have that then Q1 is the median of the lowest 5 observations, hence 19 (14,16,19,19,20, the 3rd observation is 19). Similarly, we get that the median for the upper half of the observations, Q3 namely, is 22 (21,21,22,22,23, the 3rd observation is 22). Thus, the interquartile range is 3=Q3-Q1. According to our calculations, all observations are wrong.
Answer:
2/3 + 3/4 = 1 52/125. That plus 3 is 4 / 52/125. Sorry if this isn't the right answer.
Answer:
101/3 or 33 2/3
Step-by-step explanation:
7 2/15=107/15
9 13/15=138/15
107/15+52/3+138/15
107/15+138/15+52/3
245/15+52/3
245/15+260/15
505/15
simplify,
101/3
