Given: 76,45,64,80,92
Required: Determine the standard deviation
We start by calculating the mean
Where x-> 76,45,64,80,92 and n = 5
Subtract Mean (71.4) from each of the given data
Determine the absolute value of the above result
Square Individual Result
Calculate the mean of the above result to give the variance
Hence, Variance = 255.298
Standard Deviation is calculated by
Answer:
Please check the explanation.
Step-by-step explanation:
Given
- The length of rectangular field = l = 240m
- The breadth of rectangular field = w = 200m
We can determine the area of the rectangular field using the equation
where
is the length
is the width
substituting l = 240m, and w = 200m in the formula
A = 240 × 200
A = 48000 m²
Given that the cost of digging the field at Rs 10 per m².
Thus,
The cost of digging the field of the area 48000 m² = 10 × 48000
= 480000 Rs
Therefore, the total cost of digging = 480000 Rs
