the width of Yun's area model is 7x units or ( x-2 )units .

<u>Step-by-step explanation:</u>

Here we have , Yun was trying to factor 7x^2-14x.  He found that the greatest common factor of these terms was 7x and made an area model:  What is the width of Yun's area model. Let's find out:

We know that area of rectangle :

⇒ Area = length(width)  .........(1)

Now , According to question we have

⇒ Area = 7x^2-14x

⇒ Area = 7x(x-2)

Comparing this equation to equation (1) we get that :

⇒ width = 7x or , width =x -2

Therefore , the width of Yun's area model is 7x units or ( x-2 )units .

Answer:

C. P- value < 0.04 0.05

Step-by-step explanation:

hello,

we were given the sample size, n = 200

also the probability that the psychic correctly identifies the symbol on the 200 card is

p=\frac{50}{200}= 0.25

using the large sample Z- statistic, we have

Z=\frac{p- 0.20}{\sqrt{0.2(1-0.2)/200} }

   = \frac{0.25-0.20}{\sqrt{0.16/200}}

    = 1.7678

thus the P - value for the hypothesis test is P(Z > 1.7678) = 0.039.

from the above, we conclude that the P- value < 0.04, 0.05

Answer:

See below ↓

Step-by-step explanation:

19.

  • \frac{x-1}{2} - \frac{x-3}{5} - \frac{x-7}{10} + \frac{x-2}{5}
  • \frac{5(x-1)-2(x-3)-(x-7)+2(x-2)}{10}
  • \frac{5x-5-2x+6-x+7+2x-4}{10}
  • \frac{4x+4}{10}
  • \frac{2x+2}{5}

20.

  • \frac{2x+3}{2x} + \frac{x+3}{4x} - \frac{18x+6}{8x^{2} }
  • \frac{4x(2x+3)+2x(x+3)-(18x+6)}{8x^{2} }
  • \frac{8x^{2} +12x+2x^{2} +6x-18x-6}{8x^{2} }
  • \frac{10x^{2}-6}{8x^{2} }
  • \frac{5x^{2}-3}{4x^{2} }
