We cannot calculate the mean without knowing the values of x. Therefore, we must use the given information to calculate the mean. Using the formula for mean (sum of all values divided by the number of values), we get:

mean = (3.5x + 1.2 + 0.4 + 4.1x + 0.3x) / 6
mean = (8.9x + 1.6) / 6
mean = 1.48x + 0.27

Now, if we substitute x = 1 into this formula, we get:

mean = 1.48(1) + 0.27
mean = 1.75

Therefore, the mean value of x is 1.75, which is closest to choice D, 2.16.
