Invested at 7%: s
Invested at 5.5%: f
Then s+f=$15000, or f= $15000-s
Then add together the 2 interest amounts:
i = s(0.07) at 7%
i = f(0.055) at 5.5%
Then 0.07s + (15000-s)(0.055) = $952.50
Solve this for s, the amt. invested at 7%:
0.07s + 15000(0.055) - 0.055s = 952.50
Combining the s terms,
0.015s = 952.50-825
952.50-825
Then s = ------------------- = 8500
0.015
Ruth invests $8500 at 7% and $6500 at 5.5%.

The type of statistical technique that is employed in future predictions of outcomes based on presented data is: C. linear regression.
<h3>What is a Linear Regression?</h3>
Linear regression can be described as a statistical technique that is used to make future predictions using the regression equation of a line of best fit that models the relationship between variables Y and X.
Through the regression equation, outcomes of the future can be predicted. This statistical technique is known as: C. linear regression
