The average composition of magma in a composite volcano is andesitic. Composite volcanoes are highly variable though. They can erupt anything from basalt to rhyolite.
Between 1910 and 1913, Ty Cobb's composite average was .402. Between 1921 and 1925, Rogers Hornsby's composite average was also .402.

Yes, it is a 'stratovolcano' During the last 10,000 years Shasta has erupted an average of every 800 years but in the past 4,500 years the volcano has erupted an average of every 600 years. The last significant eruption on Shasta may have occurred 200 years ago
The average composition of rocks comprising a large composite cone or stratovolcano is the same with an andesitic magma. It has an intermediate composition, with aphanitic to porphyritic texture.
The average composition of rocks comprising a large composite cone or stratovolcano is andesitic magma. It is the intermediate type between basaltic and dacitic magma.
