Answer:
5:6 --> 10:12
Step-by-step explanation:
A good way to think of this is to provide a perspective: there are 5 boys every time there is 6 girls. So if there is 10 boys, that means there would be 12 girls (because 5 *2 = 10 and 6*2 = 12).
tl:dr: 5 *2 = 10 so 6*2 = 12
We know that
the length of a circumference=2*pi*r
for r=8 ft
the length of a circumference=2*pi*8---------> 16π ft
if 2π radians (full circle)-------------------> has a length of 16π ft
3π/4 radians-------------------------------> X
X=3π/4*16π/2π-------------> X=6π<span> ft
the answer is
6</span>π ft
Answer:
877.419 , 877.078 , 836.219
Step-by-step explanation:
Answer:
415
Step-by-step explanation:
Confidence Level = 98%
Z-value for this confidence level = z = 2.326
Margin of error = E = 0.08
Mean = u = 6.6
Standard deviation =
Required Sample Size = n = ?
The formula for margin of error is:
Re-arranging the equation for n, and using the given values we get:
Thus, the minimum sample size required to create the specified confidence interval is 415
