Thats just asking the perimeter... 120 + 120 + 53 + 53 = 346 yards
Answer:
d=8.0 meters
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h
We are given the volume and the height
117.23 and the height 7
117.23 = 1/3 *3.14 *r^2 * 7
117.23 = 7.3266666666 *r^2
Divide each side by 7.3266666666
117.23/7.3266666666 = 7.3266666666 *r^2/7.3266666666
16.00045496 = r^2
Take the square root of each side
sqrt(16.00045496) =sqrt( r^2)
4.000 = r
We found the radius but it wants the diameter
d = 2*r
d =2*4.0
d=8.0 meters
248 divided by 8 gives you 31.
So it takes him 1 hour to read 31 pages.
Divide 310 by 31 and you’ll get 10.
It takes him 10 hours to read 310 pages.
Hope this helps:)
Answer:
1.07^(-2)
Step-by-step explanation:
First, figure out what 10 to the fourth power is. This will give us 10,000.
Now, divide 107 by 10,000. That gives us 0.0107. Now put this in exponential.
In expoential, we get 1.07^(-2)
Answer: (53.49%, 62.51%)
Step-by-step explanation:
Given : A poll found that 58% of U.S. adult Twitter users get at least some news on Twitter.
i.e. p= 0.58
The standard error for this estimate was 2.3%
i.e. S.E.=0.023
Critical value for 95% confidence : 
Confidence interval : 
i.e. 
Conclusion : We are 95% confident that the true population proportion of U.S. adult Twitter users who get some news on Twitter falls in interval (53.49%, 62.51%)
