Answer:
0.3165
Step-by-step explanation:
This is a binomial distribution problem
Binomial distribution function is represented by
P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ
n = total number of sample spaces = number of adults sampled = 9
x = Number of successes required = number of selected adults that say they were too young to get tattoos = 0
p = probability of success = probability of an adult that regrets getting a tattoo saying they were too young to get the tattoo = 12% = 0.12
q = probability of failure = 1 - p = 1 - 0.12 = 0.88
P(X=0) = ⁹C₀ (0.12)⁰ (0.88)⁹⁻⁰
P(X=0) = 0.31647838183 = 0.3165
Hope this Helps!!!
23.75 = 24 I'm pretty sure what you're doing here is rounding/simplifying to the next number.
Answer:
22
Step-by-step explanation:
first find the square root of all the sides then add them up and divide by two and your answer should be 22 hope this helps
Answer: the equation is zero in the middle. The rest of your numbers are around the graph.
