Answer:
C
Step-by-step explanation:
180-33-88 equals 59 and in order for the two triangles to be congruent it would need to be 58, which is present as an angle in the other triangle
Answer:
sam 30, Bethan 24
Step-by-step explanation:
54/9 = 6
sam = 5 * 6 = 30
Bethan = 4 * 6 = 24
First you multiply 3 by 2.5 by 5 which should give you 37.5. For the other one you do the same but you multiply 4 by 3.5 by 4.5, it would be 63.So the second one has more volume
Answer:
A) probability of failure in next 100 hours given that it has been tested for 500 hours without failure is 0.181
B) probability that exactly two have the metabolic defect is 0.03
Step-by-step explanation:
Part A)
Let X be a exponentially random variable with mean = μ = 500 hrs
For exponential distribution:
λ = 1/μ
λ = 0.002
We have to find the probability of failure in the next 100 hours given that assembly has been tested for 500 hours without a failure.
Using memory less property of exponential distribution:
using
<h3>Part B)</h3>
Chances of occurrence of metabolic defect = 5%
P(C) = .05
No. of randomly selected infants = n =6
We have to find the probability that exactly two have the metabolic defect
⇒x = 2
Using binomial probability density function:
P =
probability that exactly two have the metabolic defect is 0.03
