Answer:
6
Step-by-step explanation:
The measure of angle theta is 30 degrees.
This is a 30-60-90 triangle where the short leg is half that of the hypotenuse. The short leg is opposite the smallest angle 30 degrees.
You can use trig to find that
sin(angle) = opposite/hypotenuse
sin(theta) = 5/10
sin(theta) = 0.5
theta = arcsin(0.5)
theta = 30 degrees
<span>The volume of the cylinder will be 2</span>π
As shown in figure, R is the base
radius of the cylinder.
H is the height of the cylinder.
Given: H = diameter of the base of
cylinder.
Now, diameter of the base = 2R
So, H = 2R
<span>Volume of cylinder = π×</span>×H
<span> = π×</span>×(2R)
<span> = 2 π </span> cubic units.
im not sure if it is right but i got 920 cm2. is that one of ur answers?
Answer:
n=3.8416≅4
So Minimum Sample Size is 4
Step-by-step explanation:
In order to find the minimum sample size, the formula we use will be:
Where:
n is sample size
Z is the distribution
S is the standard deviation
E is the Margin of error
S=3 ,E=3
For Z:
Alpha=1-0.95=0.05
Alpha/2=0.025=2.5%
From Cumulative Standard Distribution Table:
Z at Alpha/2 = 1.960
n=3.8416≅4
So Minimum Sample Size is 4
