Sorry I also need help with this question

Tomtit [17]

Answer: B

Step-by-step explanation:

(f/g) means to divide f(x) by g(x).

$(f/g)(x)=\frac{3x+2}{3x-5}$

To find the domain, you set the domain equal to zero and solve for x.

3x-5=0 [add both sides by 5]

3x=5 [divide both sides by 3]

x=5/3

Now, we know that B is the correct answer.

the standard deviation of 100 random samples of the same size is approximated to be 0.98. what is the margin of error

pogonyaev

Answer:

MOE= ± 0.098

Step-by-step explanation:

-The margin of error is calculated using the formula:

$MOE=\pm \frac{\sigma}{\sqrt{n}}$

#Substitute to solve for MOE:

$MOE=\pm \frac{\sigma}{\sqrt{n}}\\\\=\frac{0.98}{\sqrt{100}}\\\\=\pm 0.098$

Hence, the margin of error is ± 0.098
