Answer: 1/4+3/8+1/2+5/8+7/8
= 21/8
Hope this helps :)))
Step-by-step explanation:
The data is already in ascending order.
The lower half of the data (120, 140, 160)
has the median 140.
180 is the median of the entire data.
The upper half of the data (200, 220, 240)
has the median 220.
Interquartile Range = 220 - 140 = 80.
Answer:
(i) 22.5
(ii) 7.2
Step-by-step explanation:
(i)
AB:PQ = 2:5 = 1:2.5
So PQ is 2.5 times longer than AB.
PQ=2.5AB=(2.5)9=22.5
(ii):
Since the triangles are similar, their sides are in ratio to each other. So if PQ was 2.5 times longer than AB, QR must also be 2.5 times longer than BC:
QR=2.5BC
BC=QR/2.5=18/2.5=7.2
Answer:
Step-by-step explanation:
The area of a parallelogram is base times height.
Multiply 16ft by 18ft.
(16)(18) = 288
The parallelogram is 288 ft².
