Let h = (v0^2)/4.9 sin(theta)cos(theta) model the horizontal distance in meters traveled by a projectile? if the initial velocity is 52 meters/second, which equation would you use to find the angle needed to travel 200 meters?
a) 275.92sin(2theta)=200
b) 551.84sin(2theta)=200
c) 200sin(2 theta)=200
d)10.61sin(2theta)=100

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
