3 0

Answer:

(0,5)

Step-by-step explanation:

Just plug them in:

2x - y = 10

- 2 (0) - (5) = 10?

no because 2 x 0 is 0. That would mean -5 = 10. which isn't true

- 2 (10) - (10)?

yes because 2 x 10 is 20. Subtract 10 from that and you get 10. so 10 =10

- 2 (5) - (0)?

yes because 2 x 5 is 10. There is nothing to subtract from 10 so you get 10. 10 =10.

If the data for the heights of players on a basketball team is skewed right, which statistical measure represents the spread of

mestny [16]

Answer:

Median

Step-by-step explanation:

I know that you can't do Range, since it's skewed right.

The mean can't be it since it's also not representative when it's skewed right.

I'd say Median, or IQR at first glance but if you look at a graph, the IQR might follow with the skewed and move over a bit.

That leaves Median.
