Are total emissions or per-capita emissions a better gauge when comparing the CO2 emissions of various countries? Why? Emissions per capita is a better gauge because countries with higher populations would be expected to have higher CO2 emissions. Total emissions are a better gauge because they let you see how much each country is producing. Emissions per capita is a better gauge because it shows the number of people divided by the emissions per country. Total emissions are a better gauge because it doesn't use the population.

add an image, and i will answer

step-by-step explanation:

i dont have an answer

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

i believe that the answer is

b. y-1=-2(x-4)

hope this !
