Question 1
An eagle is flying from point A to B in order to catch a sparrow. Its flight path is a parabola that can be modeled by an equation y= -5(x-6)^2+30, where x is the horizontal and y is the height of the eagle in meters.
If the eagle starts and ends at a height of 20 meters, how far away are points from one another? Round to the nearest whole number.
Question 2
The graph of the line x+y=b is a perpendicular bisector of the line segment from (1,3) to (5,7). What is the value of b?

Acell phone company offers two plans to its subscribers. at the time new subscribers sign up, they are asked to provide some demographic information. the mean yearly income for a sample of 40 subscribers to plan a is $45,000 with a standard deviation of $9,200. for a sample of 25 subscribers to plan b, the mean income is $64,300 with a standard deviation of $7,100. at the 0.025 significance level, is it reasonable to conclude the mean income of those selecting plan b is larger? assume unequal population standard deviations. hint: for the calculations, assume the plan a as the first sample. what is the decision rule? (negative amount should be indicated by a minus sign. round your answer to 3 decimal places.) compute the value of the test statistic. (negative amount should be indicated by a minus sign. round your answer to 2 decimal places.) what is your decision regarding h0 ? reject h0 fail to reject h0 compute the p-value. less than 0.01 between 0.01 and 0.025 between 0.025 and 0.05 between 0.05 and 0.10 greater than 0.10
