Answer:
0.8
Step-by-step explanation:
We can solve P(A or B) by using the following:

Since we know P(A) = 0.6, P(B) = 0.3 and P(A and B) = 0.1 we obtain:

Answer:
V = 267.9 in^3
Step-by-step explanation:
V = 4/3 * (pi) * r^3
V = 4/3 * 3.14 * 4^3
V = 4/3 * 3.14 * 64
V = 256/3 * 3.14
V = 803.84/3
By scientific notation I am assuming you mean standard form, as that is used primarily in scientific calculations. The answer in standard form would be

I hope this helps!
Step-by-step explanation:
"congruent" for lines simply means they are equally long.
