The answer is
C.
Adding any positive value to
won't really make
into a rational number, so the way you have to do it add the negative self, -
to make it into 0. Any number plus its negative value would result in 0, which is a rational number.
The Domain and Range of tan(x) are mathematically given as
Domain
Range: all Real numbers
<h3>What is The Domain and Range of
tan(x)?</h3>
All real numbers are in the domain of the function "y=tan (x)," with the exception of the value "" for all integers n, which is the case when cos(x) = 0.
It follows that "" is not in the domain of "tan (x)" among the possible values.
In conclusion,
Domain
Range: all Real numbers

Answer:
5.579 * or 0.00005579 %
Step-by-step explanation:
In this question, you select 11 random adults, so the order is not important and we should use combination instead of permutation. There are two different probability here
A= chance that the adults need correction= 0.81
B= chance that the adult doesn't need correction = 0.19
The case that can fulfill the condition of no more than 1 of 11 adults need correction is:
1. 0 adult need correction = 0C11 *
2. 1 adult need correction = 1C11 * *
Then the probability will be:
0C11 * +1C11 * * =
* + * *0.81 =
5.579 * = 0.00005579 %
The threshold for a significant value that widely used is 5% and the chance is lower than 5%, so no more than 1 adult need correction is a significantly low number of adults requiring eyesight correction?
Answer:
the answer is the last one.
Step-by-step explanation:
First we multiply both sides of the inequality by -24 to isolate the variable.
Then, since we are multiplying with a negative number, the inequality sign flips.
All we do next is calculate.
Step by step we have
