Answer:
Inverse of F(x)=9x = 1/9x
Step-by-step explanation:
If F(x)=9x
which of the following is the inverse of F(x)
When talking about inverse of a function, we are talking about reversal. Therefore, an inverse function is the inverse of another function. In order to get the inverse of a particular function, we reverse the denominator to become the numerator and the numerator to become the denominator.
So for the function,
F(x)=9x, the numerator is 9x and the denominator is 1
Reversing the numerator and denominator, .
Inverse of F(x)=9x = 1/9x
Answer:
<h3>In an independent groups experiment, if we must estimate the population standard deviation to determine the significance of the sample results, the appropriate inference test is the<u> t test</u></h3>
Step-by-step explanation:
In an independent groups experiment, if we must estimate the population standard deviation to determine the significance of the sample results, the appropriate inference test is the<u> </u><u>t test</u>
<h3>For :</h3>
- A t-test is one of the methods of a statistic and is used to determine if there is a significant difference between the two groups of their means based on a sample in data.
- The statistical significance is determined by the difference between the averages of group size , the sample size, and standard deviations of the groups.
<h3>Therefore option c) t test is correct</h3>
-2/3*3=-6/3=-2. That is how you do this.
The altitude is 177 feet below sea level after being lowered.
The balloon rises 120 feet after 12 seconds and then is dropped 15 feet. So 120 - 15 = 105. And 282 - 105 = 177
