Identify the restrictions on the domain of f(x) = quantity x plus 5 over quantity x minus 2. x ≠ 5 x ≠ −5 x ≠ 2 x ≠ −2
horsena [70]

Answer: Third option.

Step-by-step explanation:

By definition, Rational Functions have the following form:

f(x)=\frac{P(x)}{Q(x)}

Where P(x) and Q(x) are polynomials.

The Restrictions of the Domain of Rational Functions are those Real numbers that make the denominator equal to zero, because the division by zero is not defined.

 In this case, you have the following Rational Function:

f(x)=\frac{x+5}{x-2}

The Restrictions of the Domain can be found applying this steps:

- Make the denominator equal to 0:

x-2=0

- Solve for "x":

x=2

Then, the Domain of this function includes all "x" not equal to 2.

Therefore,  the answer is:

x\neq 2

zhenek [66]

Answer:

s= \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}

And replacing we got:

s= 0.286

And then the estimator for the standard error is given by:

SE= \frac{0.286}{\sqrt{4}}= 0.143

Step-by-step explanation:

For this case we have the following dataset given:

20.05, 20.56, 20.72, and 20.43

We can assume that the distribution for the sample mean is given by:

\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})

And the standard error for this case would be:

SE= \frac{\sigma}{\sqrt{n}}

And we can estimate the deviation with the sample deviation:

s= \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}

And replacing we got:

s= 0.286

And then the estimator for the standard error is given by:

SE= \frac{0.286}{\sqrt{4}}= 0.143

10 POINTS + BRAINLIEST TO FIRST CORRECT ANSWER!!! THANK YOU!
Fofino [41]

Answer:

The answer is A (Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit rate)

Step-by-step explanation:

Because the proportional relation is defined by k = \frac{y}{x}. If ratio is \frac{units}{1unit} then it is a rate. Unit rate means per 1 unit such as \frac{amountofmoney}{1kg} or \frac{km}{1hour} thus the correct answer is A.
