Answer:
a)
x/25 = 7/2 --> x = 25 * 7/2 = 87.5 miles
b)
x = 45/75 = 0.6 = 60%
c)
x = 1/(1/24 + 1/30) = 13 1/3 minutes
d)
x/2 + x/6 = 12 --> x = 18
Answer:
Y = - |x-1| - 2
Step-by-step explanation:
Answer:
a) Binomial distribution B(n=12,p=0.01)
b) P=0.007
c) P=0.999924
d) P=0.366
Step-by-step explanation:
a) The distribution of cracked eggs per dozen should be a binomial distribution B(12,0.01), as it can model 12 independent events.
b) To calculate the probability of having a carton of dozen eggs with more than one cracked egg, we will first calculate the probabilities of having zero or one cracked egg.
Then,
c) In this case, the distribution is B(1200,0.01)
d) In this case, the distribution is B(100,0.01)
We can calculate this probability as the probability of having 0 cracked eggs in a batch of 100 eggs.
Multiply 200 by .15, since 15% is .15 as a decimal. 200 x .15 = 30. This means that his health care rate will increase by $30 next year.
