At the district competition for 5th grade jump-roper of the year, the following number of jumps without stopping were recorded per student:

203,245,237,233,90,100,100,277,265, 264,265,285,288,291,
291,290,300,224,200,257,290,279,266 ,288
find the median and mean

There actually is a mean, you take the two middle numbers, add them together then divide by two.

mean=242.83
median=265

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
