You can easily keep simplifying this fraction by 2 until you can't simplify it anymore, because they're both even.

\frac{28}{36} =  \frac{14}{18} =  \frac{7}{9}

It can be faster this way for most people, but you can also just find what number goes into both numbers evenly.
4 goes into both numbers.

28\div4=7\\36\div4=9\\\\ \frac{7}{9}

28/4 = 7,
36/4 = 9,
Place the 7 over the 9 and you get 7/9!

avanturin [10]

Answer:

The correct answer is "1668". A further solution is provided below.

Step-by-step explanation:

According to the question,

Estimated proportion,

\hat{p} = \frac{574}{1007}

  =0.57

Margin of error,

E = 0.02

Level of confidence,

= 90%

= 0.90

Critical value,

Z_{0.10}=1.65

Now,

⇒  0.02=1.65\times \sqrt{\frac{0.57\times 0.43}{n} }

 0.0004=2.7225\times \frac{0.2451}{n}

         n=\frac{2.7225\times 0.2451}{0.0004}

             =1668.21

or,

         n \simeq 1668

On the line you created from part A, mark a point D that is distinct from point C. Then, use the slope formula along with the co
ad-work [718]

The slope of AB and the slope of DC based on the information about the coordinate will be -2 and -2 respectively.

<h3>How to illustrate the information?</h3>

From the information given, we are told to use the slope formula along with the coordinates of points A, B, C, and D to find the slope.

The slope of AB based on the information will be:

= (-1 -3)/(-1 --3)

= -4/2

= 2

The slope of DC will be:

= 2-6/(1 --1)

= -4/2

= -2

Therefore, the slope of AB and the slope of DC based on the information about the coordinate will be -2 and -2 respectively.

Answer:

(a) x = -2y

(c) 3x - 2y = 0

Step-by-step explanation:

You can tell if an equation is a direct variation equation if it can be written in the format y = kx.

Note that there is no addition and subtraction in this equation.

Let's put these equations in the form y = kx.

(a) x = -2y

  • y = x/-2 → y = -1/2x
  • This is equivalent to multiplying x by -1/2, so this is an example of direct variation.

(b) x + 2y = 12

  • 2y = 12 - x
  • y = 6 - 1/2x
  • This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is <u>NOT</u> an example of direct variation.

(c) 3x - 2y = 0

  • -2y = -3x
  • y = 3/2x
  • This follows the format of y = kx, so it is an example of direct variation.

(d) 5x² + y = 0

  • y = -5x²
  • This is not in the form of y = kx, so it is <u>NOT</u> an example of direct variation.

(e) y = 0.3x + 1.6

  • 1.6 is being added to 0.3x, so it is <u>NOT</u> an example of direct variation.

(f) y - 2 = x

  • y = x + 2
  • 2 is being added to x, so it is <u>NOT</u> an example of direct variation.

The following equations are examples of direct variation:

  • x = -2y
  • 3x - 2y = 0
