The following rational equation has denominators that contain variables. for this equation, A. write the value or values of the

dsp73

Answer:

A. -4 and 4

B. No solution.

Step-by-step explanation:

The given equation is

$\dfrac{3}{x+4}+\dfrac{2}{x-4}=\dfrac{16}{(x+4)(x-4)}$

A.

Equate the denominators equal to 0 to find the restrictions on the variable.

$x+4=0\Rightarrow x=-4$

$x-4=0\Rightarrow x=4$

Therefore, $x\neq -4,4$ .

B.

We have,

$\dfrac{3}{x+4}+\dfrac{2}{x-4}=\dfrac{16}{(x+4)(x-4)}$

$\dfrac{3(x-4)+2(x+4)}{(x+4)(x-4)}=\dfrac{16}{(x+4)(x-4)}$

Multiply both sides by (x-4)(x+4).

$3x-12+2x+8=16$

$5x-4=16$

Add 4 on both sides.

$5x=16+4$

$5x=20$

Divide both sides by 5.

$x=4$

Here the solution is x=4 but it is the restricted value.

Therefore, the given equation has no solution.

If x=4,y=2,z=1,p=3,q=0 then find value of 4qy ÷ 8px + yz<br><br> plz answer correctly

german

X = 4 , y = 2 , z=1 ,p=3 ,q=0

4qy / 8qx + yz = (4*0*2) / (8*3*4) + (2*1)
= (0) / (96) + (2) = 0 / 98 = 0

Q6.4☆ Points: 2 Suppose that Angela wants to use her sample to create a 68% confidence interval for the true population median o

Andrei [34K]

Answer:

She needs a sample size of 25.

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1 - 0.68}{2} = 0.16$

Now, we have to find z in the Ztable as such z has a pvalue of $1 - \alpha$ .

That is z with a pvalue of $1 - 0.16 = 0.84$ , so Z = 0.995.

Now, find the margin of error M as such

$M = z\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

The population SD is 2 grams.

This means that $\sigma = 2$

What is the minimum sample size she needs to create a confidence interval that has a width of 0.4 grams?

She needs a sample size of n.

n is found when M = 0.4. So

$M = z\frac{\sigma}{\sqrt{n}}$

$0.4 = 0.995\frac{2}{\sqrt{n}}$

$\sqrt{n} = \frac{0.995*2}{0.4}$

$(\sqrt{n})^2 = (\frac{0.995*2}{0.4})^2$

$n = 24.8$

Rounding up:

She needs a sample size of 25.
