PLEAS I GIVE 45 POINTS PLSSS. the figure shows the heights of a diver during a dive. The diving board is at a height of 10 feet above the surface of the water in the pool. The diver's height is 16 feet at the top of the dive and negative 8 feet at the completion of the dive. What is the meaning of zero in this situation? It is the height of the diver at his lowest point.

It is the height of the diver when he begins his dive.

It is the height of the diver when he is entering the water.

It is the height of the diver when he stops going up and starts going down.

The triangles are similar. what is the value of x? show your work.

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
