he finds this graph and lears that there are currently 188,300electrical engineers in the usa how many electrical engineers are at least 55 years old

To find out how many electrical engineers in the USA are at least 55 years old, we can calculate 22% of the total number of electrical engineers.

Given that there are currently 188,300 electrical engineers in the USA:

\[ \text{Number of engineers aged 55 and older} = 188,300 \times 0.22 \]

Calculating this:

\[ 188,300 \times 0.22 = 41,426 \]

Thus, there are approximately 41,426 electrical engineers who are at least 55 years old in the USA.
