d(-3 + x) = kx + 9

Distribute d inside the parentheses.

-3d + dx = kx + 9

Subtract kx from both sides.

-3d + dx - kx = 9

Add 3d to both sides.

dx - kx = 9 + 3d

Factor x out of dx - kx.

x(d - k) = 9 + 3d

Divide both sides by d - k.

x = $\frac{9+3d}{d-k}$

If you want to simplify this even more, factor 3 out of the numerator.

All of the following are equivalent except _____. A:5 over 4. B:1.25. C:12.5%. D:125%.

earnstyle [38]

Hello, there!

5/4 = 1.25

So, we know that the answer is not A or B.

1.25 = 125%

Now, we know that the answer is not D ether.

So, the answer must be C.

I hope I helped!

Let me know if you need anything else!

Suppose babies born in a large hospital have a mean weight of 4095 grams, and a standard deviation of 569 grams. If 130 babies a

Butoxors [25]

Answer:

$P =0.3998$

Step-by-step explanation:

Let ${\overline{x}}$ be the average of the sample, and the population mean will be $\mu$

We know that:

$\mu = 4095$ gr

Let $\sigma$ be the standard deviation and n the sample size, then we know that the standard error of the sample is:

$E=\frac{\sigma}{\sqrt{n}}$

Where

$\sigma=569$

$n=130$

In this case we are looking for:

$P(|{\displaystyle{\overline{x}}}- \mu|>42)$

This is:

${\displaystyle{\overline{x}}}- \mu>42$ or ${\displaystyle{\overline{x}}}- \mu$

$P=P({\displaystyle{\overline{x}}}- \mu>42)+ P({\displaystyle{\overline{x}}}- \mu$

Now we get the z score

$Z=\frac{{\displaystyle{\overline{x}}}-\mu}{\frac{\sigma}{\sqrt{n}}}$

$P=P(z>\frac{42}{\frac{569}{\sqrt{130}}}) + P(z$

$P=P(z>0.8416) + P(z$

Looking at the tables for the standard nominal distribution we get

$P =0.1999+0.1999$

$P =0.3998$
