1 answer:

6 0

_______________________________________________________
The greatest common factor (GCF) of "20x and 35y" is: " 5 " .
_______________________________________________________
The answer is: " 5 " .
_______________________________________________________

Consider: "20x" and "35y" ;

Each of the TWO (2) terms contains "ONE" (1) [single] variable. The variable within EACH term differs from each other.

As such: "The greatest common factor (GCF) of "20x" and "35y" is the:
"greatest common factor (GCF) of "20" and "35" ;
_______________________________________________________
List the factors for each number:
_______________________________________________________
20: 1, 2, 4, 5, 10, 20 .

35: 1, 5, 7 , 35.
_______________________________________________________
The greatest common factor (GCF) of "20x and 35y" is: " 5 " .
_______________________________________________________
The answer is: " 5 " .

Your gym membership costs $33 per month after an initial membership fee . you paid a total of $228 after 6 months.

Lubov Fominskaja [6]

So, what I did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a 9 month total cost of $327. Hope from here you are able to set up your equation now you have all the information needed :)

Tanya [424]

Answer:

$ME= 2.33*\sqrt{\frac{0.096*(1-0.096)}{250}}= 0.0434$

Step-by-step explanation:

For this case we have a sample size of n = 250 units and in this sample they found that 24 units failed one or more of the tests.

We are interested in the proportion of units that fail to meet the company's specifications, and we can estimate this with:

$\hat p = \frac{24}{250}= 0.096$

The margin of error is the range of values below and above the sample statistic in a confidence interval.

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 confidence interval for a proportion is given by this formula

$\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}$

For the 98% confidence interval the value of $\alpha=1-0.98=0.02$ and $\alpha/2=0.01$ , with that value we can find the quantile required for the interval in the normal standard distribution.

$z_{\alpha/2}=2.33$

And the margin of error would be:

$ME= 2.33*\sqrt{\frac{0.096*(1-0.096)}{250}}= 0.0434$

I need help I<br> don’t understand what the answer is!

Answer:

x = -4

Step-by-step explanation:

You kind of didn't capture the directions in your image, but it looks like maybe they want you to write the equation of the line.

So this is what you need to know: the equation of a vertical (up and down) line is

x = anumber

For future reference on the next question, the equation of a horizontal (flat, left and right) line is

y = anumber

For this question, though, it's vertical.

so x = -4

You can check by picking as many points as you like and find that they ALL have -4 as the x value. Also, you will find the slope formula gives you an answer that is undefined. That's why you can't write an equation using y=mx+b. Hope this helps! I can edit if the question is something wildly different for real.

A farmer has 220 bushels of apples to sell at roadside stand. She sells an average of 14 3/5 each day. Represent the total chang

Lyrx [107]

Answer:

Step-by-step explanation:

He has sold (16+1/4) bushels/day x 5 days = (16 x 5) + (1/4 x 5) = 80 + 5/4 = 81 + 1/4 = 81.25

The change in the number of bushels is 140 - 81.25 = 58.75 or 58 and 3/4 bushels

In other words, he has 58.75 (or 18 and 3/4) bushels remaining and has sold 81.25 (or 81 and 1/4) bushels
