Answer:

1/5.

Step-by-step explanation:

First you have to add up all of the numbers: 12+12+4+6+26. Then you have to find how many red marbles there are, which this case there are 12, so you get your fraction of 12/60 which can be reduced to 1/5.

The exponential model indicates that hydropower energy generation has increased by 2.3% (0.023).

<h3>What is an exponential function?</h3>

An exponential function can be defined as a type of mathematical equation whose numerals are generated by a constant that's raised to the power of an argument.

Based on an exponential model for this data, we can deduce the following:

Mathematically, the exponential function for the given data is given by $y = 1276.6e^{0.023x}$

The exponential model indicates that hydropower energy generation has increased by 2.3% (0.023).

Hydropower energy generation in 25 years after 1970 was closest to 2270 TWh.

Because the correlation coefficient indicates a strong correlation between the model and the data, this prediction can be accepted with confidence interval of 98.7%.
