Write an equation for a line parallel to y= 1/2x +4 that goes through the point (3, 5)

a) y-3 = -2(x-5)

b) y-5 = -2(x-3)

c) y-3 = 1/2(x-5)

d) y-5 = 1/2(x-3)

Suppose a ball is dropped fromca height of 6ft. it bounces back up but time it bounces, it reaches only 7/10 of its pervious height. what is the total of each height that the ball reaches after 5 bounces

Yvaries directly as x. y =90 when x=6. find y when x=13

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?
