The predicted strength is an illustration of linear regression.
The predicted strength of a weld with a diameter of 51 is -503.2.
<h3>What is linear regression?</h3>
Linear regression strives to show the relationship between two variables by applying a linear equation to observed data.
The equation of the predicted strength is given as:
Strength = -941.6992 + 8.5988 × Diameter
Substitute 51 for diameter
Strength = -941.6992 + 8.5988 × 51
Strength = -941.6992 + 438.5898
Strength = -503.1604
Strength = -503.2
Hence, the predicted strength of a weld with a diameter of 51 is -503.2.
