Final answer:
Without additional context or the value for x3, the task is to solve for x4 in the incomplete equation: ____ + x4 * 2 = 29.5. The formula for x4 is (29.5 - x3) / 2, but we cannot provide a numerical answer without knowing x3.
Step-by-step explanation:
It appears that the original question is not complete, and the context of x3 and x4 in statistics is not fully provided. However, if x4 is being sought in an equation like _____ + x4 * 2 = 29.5, we can solve for x4. Assuming the blank represents an unknown value x3 that we may or may not need to solve for, and focusing on finding x4, here's the solution:
- x3 + x4 * 2 = 29.5
- 2x4 = 29.5 - x3
- x4 = (29.5 - x3) / 2
Without the value of x3, we cannot provide a numerical answer for x4. The value of x4 is dependent on the unknown value x3.
