Use newton raphson method to Find an approximate root of x3
-5x+3 = 0 that lies in
[0,1]. Find the approximation to three decimal places.
- Two given lines are either parallel, skew or intersecting. (6 marks)
- Determine, if there is one, the point of intersection of the lines given by the equations
x−1/−3=y−8/6=z−3/−2 and x−8/4=y+3/−5=z−7/2
b. Give the equations of two lines that meet at the point (–1 5, 2) and which meet at right angles, but do not use that point in either of the equations. Explain your reasoning
The Malayo Colleges Mindanao recently conducted a study analyzing the privacy management habits of teen internet users. In a group of 192 teens, 68 reported having more than 100 followers on Twitter. Find the upper bound of a 90% confidence interval for the true proportion of teens who would report having more than 100 followers on Twitter.
