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

Step-by-step explanation:
Answer:
SMA= 24 degrees
Step-by-step explanation:
add the other given angles together: 66 + 90= 156
subtract 158 from 180 (every triangle has a total of 180 degrees): 180-156 = 24
Answer:
Step-by-step explanation:
slant height is given. Using Pythagorean theorem to find height.
h² = 10² - 5²
= 100 - 25
h² = 75
h = √75
h = 8.66 cm
Volume =(1/3)πr²h
= 226.62 cubic cm
54,273 = A * 1.70^6 where A is the initial number
A = 54273/1.70^6 = 2248
