Box plot allows us to determine the mean, the largest or the lowest number in the data set as well as the quartiles in the data. In this case, from the given figure, median is equal to 18, the range is equal to 21-15 equal to 6. The 25th percentile is equal to17 while the 75th is equal to 20. IQR then is equal to 20-17 equal to 3.
79.30 ---- 100%
The while store is discounted by 12% So subract 12 from 100
100-12 = 98
We have to figure out what 88% is
79.30 ---- 100%
X ------------ 88%
Cross Multiply
79.3× 88 = 100x
6978.4 = 100X
69.784 is without taxes
69.784 = 100% {100% because it is the total price.}
69.784 = 100%
X --------- 6.25%
Cross Multiply
69.784 × 6.25 = 100X
436.15 = 100 X
X = 4.3615
69.784 + 4.3615
74.15 is the answer

Step-by-step explanation:
Answer:
31.5
Step-by-step explanation:
Area of a rectangle = lw
Substitute: 7*3 = 21
Area of a Triangle = 1/2*bh
Substitute: 1/2*(3)(7) = 10.5
Area = 21 + 10.5 = 31.5
Answer:
33
Step-by-step explanation:
area of large triangle = 117
117-(30)-(12*5/2)-(8*6/2)
= 33
