Which value is closest to the unit length of GF in the coordinate plane below ?

Tresset [83]

Answer:

$GF=11\ units$

Step-by-step explanation:

we know that

Applying The Pythagorean Theorem in the right triangle GHF of the figure

$GF^2=GH^2+HF^2$

we have

$GH=6\ units\\HF=9\ units$

substitute

$GF^2=6^2+9^2$

$GF^2=36+81$

$GF^2=117$

$GF=10.8\ units$

Round to the nearest unit

$GF=11\ units$

Keisha wants to estimate the percentage of managers at her company that hold an MBA. She surveys 320 managers and finds that 70

Answer:

The margin of error is of 0.038 = 3.8%.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

$n = 320, \pi = \frac{70}{320} = 0.21875$

90% confidence level

So $\alpha = 0.1$ , z is the value of Z that has a pvalue of $1 - \frac{0.1}{2} = 0.95$ , so $Z = 1.645$ .

The margin of error is:

$M = z\sqrt{\frac{\pi(1-\pi)}{n}}$

$M = 1.645\sqrt{\frac{0.21875(1-0.21875)}{320}}$

$M = 0.038$

The margin of error is of 0.038 = 3.8%.

Which number is an integer? 1, 0.5, 3/2

aksik [14]

An integer is any whole number (not fractions) that can be either negative or positive.

1 is the only integer because 0.5 and 3/2 are not whole numbers and are fractions, while 1 is a whole number.

Can you please help me list the forms As_,_ and limits

Anastasy [175]

Given the function:

$f(x)=\frac{2x+1}{x}$

First, the graph of the function will be as shown in the following figure:

For the given rational function, we will find the following:

Domain = ( -∞, 0 ) ∪ ( 0, ∞ )

Range = ( -∞, 2) ∪ (2, ∞ )

Increasing = Φ

Decreasing = ( -∞, 2) ∪ (2, ∞ )

All asymptotes:

Vertical asymptote: x = 0

Horizontal Asymptote: y = 2

All limits:

$\begin{gathered} \lim _{x\rightarrow-\infty}f(x)=2 \\ \lim _{x\rightarrow\infty}f(x)=2 \\ \lim _{x\rightarrow0^-}f(x)=-\infty \\ \lim _{x\rightarrow0^+}f(x)=\infty \end{gathered}$
