A global energy council forecasted the expected worldwide wind-turbine electricity generation capacity, in gigawatts (GW), for each of six consecutive upcoming years (Y1 – Y6). For each year, the graph shows the expected  installed  wind capacity (i.e., capacity that will be newly installed during that year) and expected  cumulative  wind capacity (i.e., total existing capacity at the end of that year). The graph also shows, for each of installed and cumulative capacity, the percent rate of growth for each year over the previous year.

From each drop-down menu, select the option that creates the most accurate statement according to the information provided.

From Y1 to Y6 the graph indicates that the expected annual percent rate of growth for cumulative wind capacity will  GRAPH_1_PLACEHOLDER .

To the nearest 50 GW, the median of the expected cumulative wind capacities from Y1 to Y6 is  GRAPH_2_PLACEHOLDER .

Black line graph is slightly reducing.

first box : attention to "growth for cumulative in percentage", it means line black dot with the number of right side, which decreased

second box : atention to "expected cumulative", it means blue graph with the number of left side, which the middle of it is approximately reach number 520 and 480, and avarage of them (since there is not only one number as median) is 500.

Hey  Bunuel   MartyMurray   chetan2u   KarishmaB !

Can you help with the 2nd drop-down cause I believe the answer should be 550.

Y1 - 380
Y2 - 410
Y3 - 480
 Y4 - 530 
Y5 - 600
Y6 - 670

With calculation we can see that Y4 will be the median and it seems closer to 550 than 500 to me.
Please lmk where I'm wrong.

Thanks in advance!

Theres an even number of years. So you must split the middle 2 years - (530+480)/2 is closer to 500
