Answer: There are 14 long pieces she can cut.
Step-by-step explanation:
Since we have given that
Length of yards of ribbon is given by
Length of yards of ribbon pieces need to be cut is given by
Number of yards is given by
Hence, there are 14 long pieces she can cut.
Answer:
all...
Step-by-step explanation:
The final solutions are C1=7, C2=14
Answer:
a)
b) f(2) = 0.04462
c) f(1) = 0.01487
d)
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of successes
e = 2.71828 is the Euler number
is the mean in the given interval.
In this question:
a. Write the appropriate Poisson probability function.
Considering
b. Compute f (2).
This is P(X = 2). So
So f(2) = 0.04462
c. Compute f (1).
This is P(X = 1). So
So f(1) = 0.01487.
d. Compute P(x≥2)
This is:
In which:
Then
So
14. The answer is A; 8 is the opposite reciprocal of -1/8, which is what you need for perpendicular slope.
15. The answer is C; you can guess and check by plugging points into the equation.
