Given the data

X, ...rankX.....Y.....rankY......d=rx-ry........d²

4.........4...........-5......4................0..............0

53.......3.........-1........3................0...............0

86.......2.........13.......2................0................0

162......1..........16.......1.................0...............0

Then, using the rank correlation formula

p = 1 — 6•Σd² / n(n²—1)

p = 1 - 6• 0 / 4(4²-1)

p = 1 - 0

p = 1

So, the rank correlation is 1, this means that the two variables being compared are monotonically related, even if their relationship is not linear.

Give an example of a set of data displayed in a line graph
bazaltina [42]
Normally it’s like a ratio or starts with a graph on the side so you know what goes onto what part for example if you have a line graph you have 2 numbers.. so the y axis could be days and the x axis could be animals... so the graph would be showing how many animals per day... so it could be written out as 3:4 3,4 or how ever your teacher has you wrote them.. so then you would go on the X axis and find the 3 then go up 4 on the y axis and put a dot right at that point.

TriangleABC is a right triangle. if AC=15 and BC=17, what is AB
sergey [27]

Answer:

The answer in the procedure

Step-by-step explanation:

I will analyze two cases

see the attached figure to better understand the problem

case a) applying the Pythagoras Theorem

I assume that the hypotenuse is BC

AB^{2}=BC^{2}-AC^{2}

substitute the given values

AB^{2}=17^{2}-15^{2}

AB^{2}=64

AB=8\ units

case b) applying the Pythagoras Theorem

I assume that the hypotenuse is AB

AB^{2}=BC^{2}+AC^{2}

substitute the given values

AB^{2}=17^{2}+15^{2}

AB^{2}=514

AB=\sqrt{514}=22.67\ units
