Answer:

  x = 500 g

Step-by-step explanation:

You want the value of x, given that the median of the histogram shown is 175 g.

Median

The median of the set of data is the value that separates the upper half from the lower half of the data set.

Here, there are as many colored squares (14) above the 4th bar as there are below the 4th bar. That means the median can be estimated as being in the middle of the 4th bar, at bar 3.5.

Maximum

If bar 3.5 corresponds to 175 g, then the upper end of bar 10 will correspond to ...

  (10/3.5)(175 g) = 500 g

The value of x is 500 g.
