Answer:
87.29%
Step-by-step explanation:
Given: Mean= 68.8 inches
Standard deviation= 2.8 inches
Now, finding the percent of the men in the sample were greater than 72 inches.
We know, z-score=
z-score=
⇒ z-score=
∴ z-score= 1.14
Next, using normal distribution table to find percentage.
Coverting 0.8729 into percentage=
We get the percentage as 87.29%
Hence, 87.29% of the men in the sample were greater than 72 inches.
Answer:
The volume of the cylinder shown in the figure is 628 cube meters
Step-by-step explanation:
Given figure is about cylinder
The height of the cylinder = h = 8 meters
The radius of the base of cylinder = r = 5 meters
Now, let The volume of cylinder = V m³
So, The volume of cylinder is given as V = ×r²×h
where r is the radius of its base
And h is the height of cylinder
The value of = 3.14
So, V = × r² × h
Or, V = 3.14 × (5)² × 8
Or, V = 3.14 × 25 × 8
or, V = 628 m³
So, The volume of cylinder = V = 628 m³
Hence The volume of the cylinder shown in the figure is 628 cube meters Answer
