Answer: The median score will remain the same at 91.

Step-by-step explanation: The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. Write all of the numbers and cross out a even amount of numbers on both sides. Image 1 shows the problem with original numbers. Image 2 shows problem with new numbers

Can someone pls help ASAP

Vera_Pavlovna [14]

Answer:

89.44

Step-by-step explanation:

using the Pythagorean Theorem: $a^{2} +b^{2}=c^{2}$

$80^{2} +b^{2} =120^{2} \\6400+b^{2} =14400\\b^{2} = 8000\\b = 40\sqrt{5}$

120 is the hypotenuse so it would be c in the equation.

To solve, I simplified and isolated the variable. I got the square root of 8000 simplified (but idk how to write that out lol)

This answer is closest to 89.44

*Hope this helped! Have a great day/ night wherever you are! : )*
