Answer:
r = 0.7575
Explanation:
Result Details & Calculation
This is a strong positive correlation, which means that high X variable scores go with high Y variable scores (and vice versa).
X Values
∑ = 78
Mean = 15.6
∑(X - Mx)2 = SSx = 337.2
Y Values
∑ = 428
Mean = 85.6
∑(Y - My)2 = SSy = 57.2
X and Y Combined
N = 5
∑(X - Mx)(Y - My) = 105.2
R Calculation
r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))
r = 105.2 / √((337.2)(57.2)) = 0.7575
Meta Numerics (cross-check)
r = 0.7575

Answer:
A. The combustion of fossil fuels heats water to produce steam, which then turns a turbine.
Explanation:
Most heat-based generation of electricity uses steam and steam-driven turbines to actually turn the generator. This includes coal, oil, gas, and nuclear power, and some solar power as well.
The heat source is used to heat water, turning it to steam. The steam is then directed at a turbine, turning it and the attached generator to produce electricity.
