Which sample has a greater variability, or spread?

Mathematics
2 answers:
avanturin [10]3 years ago

Answer:

The orange sample

Step-by-step explanation:

The higher the interquartile range the bigger the variance as it the difference between the 0.25 and 0.75 quantiles which basically means if the difference between the 25 percent and 75 percent is higher then there is more variety as they are further away

Would be amazing if you marked brainliest and feel free to comment any follow up questions :)

I =  / r            where I = current and r = resistance

80 = k / 50 so
k = 400

so we have I = 400/r

when r = 40  
I = 400/40 = 10 amps
