Mathematics
1 answer:
egoroff_w [7]3 years ago
5 0

Answer:

The answer is x = 5.

Step-by-step explanation:

hyp=leg√2

10=a√2

both sides divided by √2

10 over √2 = a

multiply top and bottom by √2 and you will get 10√2 over 2

simplify and get 5√2

now to get x

5√2=x√2

both sides divided by √2 will get you

5√2 over √2 = x

simplify to get 5 times 1 which is 5 = x

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
