Answer:
Then the probability that exactly 6 bridges in the sample are structurally deficient is 0.1063 or 10.63%
Step-by-step explanation:
Let X the random variable of interest "number of bridges in the sample are structurally deficient", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:
And if we use the probability mass function and we replace we got:
Then the probability that exactly 6 bridges in the sample are structurally deficient is 0.1063 or 10.63%
Answer:
D.
Step-by-step explanation:
in order to choose the correct answer, it is enough to substitute the given coordinates [(-3;-1) and (-6;8)] into the equations:
A. -1-8=3(-3+6); ⇔ -9≠9; wrong
B. -1+8=-3(-3+6); ⇔ 7≠-9; wrong
C. -1+8=3(-3-6); ⇔ 7≠-27; wrong
D. (-3;-1): -1-8=-3(-3+6); ⇔ -9=-9
(-6;8): 8-8=-3(-6+6); ⇔ 0=0 - correct.
Note, the suggested way is not the only one.
PS. the given points are (-3;-1) and (<u>-6;</u>8).
Answer:
Step-by-step explanation:
Prime numbers are numbers that are divisible by itself and '1'. This means prime numbers are numbers with just two factors while composite numbers are numbers that are divisible by more than two numbers, that is they have more than 2 factors.
Example of prime numbers are 5,7,11 etc. We see that these numbers are only divisible by themselves and by '1' while examples of composite numbers are 10, 15, 20, etc. We clearly see that these numbers have more than 2factors.
Box A is the plot that represents the data set hope this helps:)
Answer:
v = 340 cm³
Step-by-step explanation:
base area = 12 x 10 x 0.5 = 60 cm²
v = 60 x 17 x 1/3 = 340 cm³
