Using<u> rounding concepts</u>, it is found that the error interval for n is:
The number is rounded to two decimal places, hence:
From this, we have that values between 3.865(inclusive) and 3.875(exclusive) are rounded to 3.87, which means that the error interval is:

Answer:
Step-by-step explanation:
The zeros of the polynomial are all the values of x for which the function
In this case we know that the zeros are:
,
Now we can write the polynomial as a product of its factors
Note that the polynomial is of degree 3 because the greatest exponent of the variable x that results from multiplying the factors of f (x) is 3
Answer: The maximum number of people who could answer yes for both cat and dog is 7.
Step-by-step explanation: Given that a survey of 100 people asked if they have a dog or a cat.
Out of those 100 people, 56 people answered yes for dog and 51 people answered yes for cat. Some people may own neither and some people may own both animals.
We are to find the maximum number of people that could answer yes for both cat and dog.
Let A and B represents the set of people that answered Yes for dog and Yes for cat respectively.
Then, according to the given information, we have
From Set Theory, we have
Since the total number of people is 100, so we get
Therefore, from equation (i), we get
Thus, the maximum number of people who could answer yes for both cat and dog is 7.
