Suppose a man is heterozygous for heterochromia, an autosomal dominant disorder which causes two different‑colored eyes in an individual, produced 25‑offspring with his normal‑eyed wife. of their children, 15 were heterochromatic and 10 were‑normal. calculate the chi‑square value for this observation.

Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)
