Answer:
Step-by-step explanation:
d₁ = 6 inches
r₁ = 3 inches
area = πr₁² = 9π in²
d₂ = 24 inches
r₂ = 12 inches
area = πr₂² = 144π in²
ratio of areas = (9π)/(144π) = 9/144 = 1/16
Answer:
a) 2 + 1 = 3
4 + 2 = 6
6 + 3 = 9
b) Yes
c) Yes, since you are adding b to two b, which results in 3b

Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The low yield rate is
The sample size n = 80
Hence the probability that the bottle is bad
=>
=>
Generally the distribution of yield follows a binomial distribution
i.e
and the probability distribution function for binomial distribution is
Here C stands for combination hence we are going to be making use of the combination function in our calculators
Generally the probability less than three bottles are bad is mathematically represented as
=>
=>
=>
