It would be choice b.
The domain is the range of x values which in this case is from -5 to 3.
How do people......I just don't understand this
In the binomial expansion of (0.30+0.70)²⁰ the coefficient is ²⁰C₁₀=184756 for x=10 and we have 0.30¹⁰×0.70¹⁰ for the pq values where q=1-p. This comes to about 0.03. So the statement p(x=10)=0.50 is false, answer b.
209 is the answer to you problem hope it helps
B.
X-17=-5
Add 17 to both sides
-5+17=12
