B I think I’m not sure because you did not include the type of prism... rectangular triangular? Also if your talking about lateral surface area! so 400mm squared b I think
The range of any graph are the set of all the y-values of the graph. For this graph, it goes all the way from 0 to about 3.5. I'd say the range of this graph was {0, 3.5}. Hope I could help!
Ok so basically I dunno all the corr. coefict stuff, but...
in 10 sec it went for 4 to 8, that's doubled
then from 8 to 12 is, +4, 4×3
A. Just during these two intervals we have, y/x: 4/10, then 8/20, then 12/30
0.4, 0.4, 0.4, but then it goes 15/30 = 0.5
so it's not a perfect 100% (1.00) correlation, but it would be very close [I'd choose b) 0.99]
B. from 10-30mins, it went from 4 to 8 to 12
m = change in y ÷ change in x
m = (12-4)/(30-10) = 8/20 = 0.40
C. means that the rate there is 0.40 miles per min. steady, which is 0.40 miles/min × 60min/hr = 24mi/hr steadily without increase or decrease, but a slight decrease from 30-40
RARELY say Causation, Ehr on the side of caution... correlation when in doubt
I hate school guys that's all I want to say
