Answer:
option (D) 16.5
Step-by-step explanation:
Data provided:
Sleep time of , X = 15.9 is at the 10th percentile
Standard deviation, σ = 0.5 hour
also,
10th percentile of normal distribution is
Z = F⁻¹(0.10)
or
Z = - 1.28 (Using Standard Normal distribution)
Now,

or
X = μ + ( σ × Z )
or
μ = X - ( σ × Z )
on substituting the respective values, we get
μ = 15.9 - 0.5 × (-1.28)
or
μ = 16.5
Hence, the correct answer is option (D) 16.5
Answer:
68cm^2
Step-by-step explanation:
<h2>A trapezium is a type of quadrilateral with the two opposite sides parallel.</h2>
Area of a trapezium= 1/2(sum of parallel sides)×height
Area of the trapezium= 1/2(5+3)×17
Area of the trapezium= 1/2(8)×17
Area of the trapezium=4×17= 68cm^2
