Question

amount of fossil fuels produced in the united states from 1957 to present quadrillions of btus, or british thermal units, which are used for energy. calculate the total amount of fossil fuels produced in each year and enter the values in the table. then answer the questions on a separate sheet of paper. fossil fuel production u.s. fossil fuel production (in quadrillions of btus) year coal oil natural gas total produced 1957 13.1 15.2 10.6 1967 13.8 18.7 17.9 1977 15.8 17.5 19.6 1987 20.1 17.7 17.1 1997 23.2 13.6 19.5 2007 23.5 10.8 19.8 2017 15 19 27 source is from 2016: https://www.eia.gov/energyexplained/?page=us_energy_home. data is recorded as 2017 because the latest data is not yet available. analyze and interpret data 1. construct graphs use your totals to construct a bar graph.

Explanation:

Step1: Calculate 1957 Total

Sum Coal, Oil, Natural Gas: \( 13.1 + 15.2 + 10.6 \)
\( 13.1 + 15.2 = 28.3 \); \( 28.3 + 10.6 = 38.9 \)

Step2: Calculate 1967 Total

\( 13.8 + 18.7 + 17.9 \)
\( 13.8 + 18.7 = 32.5 \); \( 32.5 + 17.9 = 50.4 \)

Step3: Calculate 1977 Total

\( 15.8 + 17.5 + 19.6 \)
\( 15.8 + 17.5 = 33.3 \); \( 33.3 + 19.6 = 52.9 \)

Step4: Calculate 1987 Total

\( 20.1 + 17.7 + 17.1 \)
\( 20.1 + 17.7 = 37.8 \); \( 37.8 + 17.1 = 54.9 \)

Step5: Calculate 1997 Total

\( 23.2 + 13.6 + 19.5 \)
\( 23.2 + 13.6 = 36.8 \); \( 36.8 + 19.5 = 56.3 \)

Step6: Calculate 2007 Total

\( 23.5 + 10.8 + 19.8 \)
\( 23.5 + 10.8 = 34.3 \); \( 34.3 + 19.8 = 54.1 \)

Step7: Calculate 2017 Total

\( 15 + 19 + 27 \)
\( 15 + 19 = 34 \); \( 34 + 27 = 61 \)

To construct the bar graph:

• X - axis: Years (1957, 1967, 1977, 1987, 1997, 2007, 2017)
• Y - axis: Total Production (in quadrillions of BTUs)
• For each year, draw a bar with height equal to the total calculated (e.g., 1957 bar height = 38.9, 1967 = 50.4, etc.). Ensure bars are evenly spaced, labeled, and axes have titles.

Answer:

Total productions: 1957: 38.9, 1967: 50.4, 1977: 52.9, 1987: 54.9, 1997: 56.3, 2007: 54.1, 2017: 61. Bar graph constructed with these values (axes: Years vs. Total Production, bars for each year’s total).
