Answer:

B) Jill omitted a factor pair, which affected the GCF and factored expression.

Step-by-step explanation:

Jill is factoring the expression 13xy-52y. Her work is shown below.

Factors of 13xy: 1, 13, x, y

Factors of 52y: 1, 2, 26, 52, y OOPSIE she forgot 4,13

GCF: y

Factored expression: y(13x-52) 13y (x-4)

Answer:

It doesn't seem like we're given quite the whole problem here but I think we're given enough to do it.

Presumably Jill's problem is GCF(13xy, 52y) which equals 13y not y.

52=4(13) so Jill omitted a factor pair, which affected the GCF and factored expression

The temperature of a chemical compound, in degrees Celsius, changes when the compound is exposed to UV light. The table below sh

sertanlavr [38]

The temperature of the compound will follow this function: 1/8x^2+15 ( I could be wrong).

But how did I come up with this function ??

The standard of a quadratic equation is given...the x is given...the f(x) is given. Now plug these in correspondence to find the constants. The rest is algebra. If you are not getting this answer, let me see your work

Change the line 3x − 8y = 5 into slope-intercept form.

Nimfa-mama [501]

Slope is y=mx+b
m=slope
b=y intercept

solve for y basically

3x-8y=5
minus 3x both sides
-8y=-3x+5
divide both sides by -8
$y=\frac{3}{8}x-\frac{5}{8}$

Bones Brothers & Associates prepare individual tax returns. Over prior years, Bones Brothers have maintained careful records

madreJ [45]

Answer:

For this case we have the following info related to the time to prepare a return

$\mu =90 , \sigma =14$

And we select a sample size =49>30 and we are interested in determine the standard deviation for the sample mean. From the central limit theorem 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 deviation would be:

$\sigma_{\bar X} =\frac{14}{\sqrt{49}}= 2$

And the best answer would be

b. 2 minutes

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 central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".

Solution to the problem

For this case we have the following info related to the time to prepare a return

$\mu =90 , \sigma =14$

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

And the standard deviation would be:

$\sigma_{\bar X} =\frac{14}{\sqrt{49}}= 2$

And the best answer would be

Convert 5.764764764 … to a rational expression in the form of a over b, where b ≠ 0

zubka84 [21]

I just learned a short time ago how to convert a repeating decimal to a fraction.

-- Take the repeating part of the decimal. In this one, it's '764' .

-- Make a fraction out of it by writing it over the same number of 9s.

   The fraction here is 764/999 .

-- Simplify it if possible and if you feel like it.

   764/999 can't be simplified. (I think.)

So the rational expressions for this decimal are

   (5 and 764/999)   or   5759/999   .
