A uniform beam of weight 245 N, and length L, sticks out from a vertical wall. A lightweight cable connects the end of the beam to the wall, making an angle of 65.0° between the beam and the cable. What is the tension in the cable?
P(x) = (2x^3+x^2-18x-9)/(x^2-x-6) 1.Find any holes in the graph of P(x) 2.Find any horizontal or oblique asymptote 3.Determine where it crosses the horizontal/oblique asymptote (if it does)
I think I have it...nevermind .94 on z chart =1.55...then multiply 1.55 times error (10) then time 60=75.5?
Typing speeds among college students are normally distributed with a mean of 60 words, and a standard deviation of 10 words. determine the typing speed that separates the top 6% typists from the rest.
142 out of 507 people were right. Calculate a 95% confidence interval for the proportion of the entire population that could be right. I did some of the work Please help. I am getting .0199 SD =sqt(.28(1-.28)/506 = .0119 so .28 +/- .0119 so I could say that with 95% conf...
I get it now...I was missing a step too! Thanks Much!
you know I am getting .0199 SD =srt(.28(1-.28)/506 = .0119? Please check for me again?
so I could say that with 95% confidence, between 24.1% and 31.9% of the entire population could be right?
142 out of 507 people were right. Calculate a 95% confidence interval for the proportion of the entire population that could be right. I did some of the work and got .72...don't know what to do with this? Please help.
