This is found using the binomial distribution with P(H) = 1/2 and P(T) = 1/2 n = 15 and r = 10
= nCr(0.5)^(15-10)(0.5)^10
= 15C10 * 0.5^15 = 0.0916 or 9.16%
I believe the correct answer is the last number line
Answer:
D. subtract 31 from both sides
you cant combine cuz theyre not like terms and you have to undo the constant number before you undo the second term in the equation so you will end up needing to do letter choice D first.
Step-by-step explanation:
hope this helped a little bit :)
It should be letter D positive 1
