Answer:
(d)
Step-by-step explanation:
When the data is put in order, the values are ...
24, 28, 32, 34, 40, 44, 49
The middle value is 34. This is the median, where the line in the middle of the box plot is located. Only one answer choice has this correctly placed.
__
When the median is removed, the data set is divided into two parts:
24, 28, 38 and 40, 44, 49
The middle value of each of these will be the lower and upper quartiles, the ends of the box in the box plot. Those are 28 and 44.
So, the box plot has whiskers that extend to the extreme data points of 24 and 49, box ends at 28 and 44, and a median line at 34. The last choice matches this description.
Answer:
The Area of the base is 16 cm² .
Step-by-step explanation:
Given as :
The surface area of the cuboid = x = 95 cm²
The lateral surface area of the cuboid = y = 63 cm²
Let The Area of the base = z cm²
Now, Let The length of cuboid = l cm
The breadth of cuboid = b cm
The height of cuboid = h cm
<u>According to question</u>
∵ The surface area of the cuboid = 2 ×(length × breadth + breadth × height + height × length)
Or, x = 2 ×(l × b + b × h + h × l)
Or, 95 = 2 ×(l × b + b × h + h × l)
Or, (l × b + b × h + h × l) = ....1
<u>Similarly</u>
∵lateral surface area of the cuboid = 2 ×(breadth × height + length × height)
Or, y = 2 ×(b × h + l × h)
Or, 2 ×(b × h + l × h) = 63
Or, (b × h + l × h) = ......2
Putting value of eq 2 into eq 1
so, (l × b + ) =
Or, l × b = -
Or, l × b =
i.e l × b =
so, l × b = 16
<u>Now, Again</u>
∵The Area of the base = ( length × breadth ) cm²
So, z = l × b
i.e z = 16 cm²
So, The Area of the base = z = 16 cm²
Hence,The Area of the base is 16 cm² . Answer
