Answer: 17.5 or 35/2
Step-by-step explanation:
(If you change 4/5 to a decimal, it makes this easier. 4/5 would be 0.8.)
23.6 = (12 + x)*0.8
23.6 = 9.6 + 0.8x
14 = 0.8x
17.5 = x
17.5 as an improper fraction would be 35/2.
Answer:
B and D.
You still need to take square roots the normal way, so square root of 4 and 36 is 2 and 6. 2/6 simplified is 1/3. Thus, the answers are B and D
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%
