Please help due by 10:10!!!!!!!!!!

sertanlavr [38]

Answer:

yes

Step-by-step explanation:

distributing gets you 8x+ 12= 2x-2 +6x+14

8x+12=8x+12

when both sides are simplified, they are equal to each other. This means that there IS a value of x that would make the perimeters equal

not sure what the drop down answers are so hope this helps

Intravenous fluid bags are filled by an automated filling machine. Assume that the fill volumes of the bags are independent, nor

iren2701 [21]

Answer:

Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:

$X \sim N(\mu,0.08)$

Where $\mu$ and $\sigma=0.08$

Since the distribution for X is normal then the we know that the distribution for the sample mean $\bar X$ is given by:

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

And the standard error is given by:

$SE= \frac{0.08}{\sqrt{24}}= 0.0163$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:

$X \sim N(\mu,0.08)$

Where $\mu$ and $\sigma=0.08$

Since the distribution for X is normal then the we know that the distribution for the sample mean $\bar X$ is given by:

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

And the standard error is given by:

$SE= \frac{0.08}{\sqrt{24}}= 0.0163$

Sue invests $600 in an account at 4.5% simple interest paid annually over the term of 10 years. What is the final value?

BaLLatris [955]

Answer:

$870

Step-by-step explanation:

To figure out how much the final value here is, use the formula A = P(1 + rt). (A = total accured amount, P = principal, r = rate (%), t = time (years))

A = 600 * (1 + (10 * 9/200)) (multiply 10 by 9 and put that over 200)

A = 600 * (1 + (90/200)) (90/200 simplifies to 9/20)

A = 600 * (1 + (9/20)) (add 1 (20/20) to 9/20 to get 29/20)

A = 600 * 29/20 (Multiply 600 by 29 and put that over 20)

A = 17400/20 (Divide 17400 by 20 to get 870)

A = 870

$870 is the final value.
