Answer:
The distributive property states that multiply the term outside of the parenthesis by each term in that parenthesis. i.e,
As per the given statement:
Take RHS:
Apply the distributive property; we have;
= LHS
Therefore, the property that justifies the sentence is Distributive property
Answer:
Is there a picture to go along with this question
Step-by-step explanation:
Answer:
0.8743 = 87.43% probability that more than one accident occurs per year
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 sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
Buchtal, a manufacturer of ceramic tiles, reports on average 3.1 job-related accidents per year.
This means that
What is the probability that more than one accident occurs per year?
This is:
In which
Then
0.8743 = 87.43% probability that more than one accident occurs per year
Answer:
The standard error of the mean is 0.85.
Step-by-step explanation:
The given standard deviation of a population (σ) = 7.8
sample size (N) = 85
We have to find standard error of the mean.
The formula to find standard error of the mean
= (standard deviation of the distribution) / (square root of sample size)
= (σ) / (√N)
= 7.8 / (√85)
= 7.8 / 9.219544457
= 0.8460
= 0.85 (approximately taken to two decimal places)
We have got the required answer.
The standard error of the mean is 0.85.
