Answer:
- ∞ < y < ∞
Step-by-step explanation:
The given function is, .
Now, the origin function of this above function is, which has real y-values as output for all real x-values input.
Hence, the function will ba valid for all real values of x and will have real y-value corresponding to each x-value.
Therefore, the range of this function i.e. the y-value of this function will be
- ∞ < y < ∞. (Answer)
Answer:
Step-by-step explanation:
Let
x------> the length of the original play space
y-----> the width of the original play space
we know that
The area of the original play space is equal to
The area of the new play space is equal to
Find the difference
Answer:
Step-by-step explanation:
Since a Binomial is an algebraic expression of the sum or the difference of two terms.
Therefore, For a binomial an expression must contain exactly two terms.
In a) there is only one term therefore it is not the Binomial.
In a) , there is only one term therefore it is not the Binomial.
In a) there is exactly two terms therefore it is a Binomial.
In a) there are three terms therefore it is not the Binomial.
Answer:
3.93% probability that both say service is poor
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The customers are chosen without replacement, and the order in which they are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
What is the probability that both say service is poor?
Desired outcomes:
Two saying it is poor, from a set of 66. So
Total outcomes:
Two customers from a set of 331. So
Probability:
3.93% probability that both say service is poor
