Answer: The answer is C- 30cm
Step-by-step explanation:
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%
The answer is 39.470 because 39.472 is far from 39.450 and it’s 2 numbers passed 39.470.
Formula: a^2+b^2=c^2
Plug in: 24^2+18^2=c^2
Exponents: 576+324=c^2
Add: 900=c^2
Square root: c=30
So the answer is 30 inches
