What is the proportion method formula?

Answers

Answer 1

Two ratios are referred to as being in proportion if they are the same. If the four elements are a, b, c, and d in that order, then a : b :: c : d = a/b = c/d.

Describe the method of proportion?When two ratios are equal, they are in proportion, based on the definition of proportion. When determining if two ratios and fractions are equivalent, this proportion formula is performed.

The following formulas also relate to proportion:

a : b :: c : d = a/b = c/d

In which,

a, d = Extreme termsb, c = Mean terms

The ratio of averages to extremes is 1:1. You can write this as ad = bc.

Two additional proportional formulas that depend on either direct or indirect variation are available. If two numbers x and y are all in direct proportion, y = kx, and when they are in indirect proportion, y = k/x, with k serving as the proportionality constant in both cases.

A quadrilateral has vertices at (1.4).
(7,3), (3, -5), and (8,4). The
quadrilateral is dilated by a scale
factor of 3.5 with the origin as its
center. What are the coordinates of
the vertices of the image of the
quadrilateral?

Answers

Given:

A quadrilateral has vertices at (1,4), (7,3), (3, -5), and (8,4).

The quadrilateral is dilated by a scale factor of 3.5 with the origin as its center.

To find:

The coordinates of the vertices of the image of the quadrilateral.

Solution:

If a figure is dilated by a scale factor k with origin as it center, then

[tex](x,y)\to (kx,ky)[/tex]

It is given that the quadrilateral is dilated by a scale factor of 3.5 with the origin as its center. So, the rule of dilation is

[tex](x,y)\to (3.5x,3.5y)[/tex]

Using this rule, we get

[tex](1,4)\to (3.5(1),3.5(4))[/tex]

[tex](1,4)\to (3.5,14)[/tex]

Similarly,

[tex](7,3)\to (3.5(7),3.5(3))[/tex]

[tex](7,3)\to (24.5,10.5)[/tex]

[tex](3,-5)\to (3.5(3),3.5(-5))[/tex]

[tex](3,-5)\to (10.5,-17.5)[/tex]

And,

[tex](8,4)\to (3.5(8),3.5(4))[/tex]

[tex](8,4)\to (28,14)[/tex]

Therefore, the coordinates of the vertices of the image of the quadrilateral are (3.5,14), (24.5,10.5), (10.5,-17.5), (28,14).

Answer:

actual area = 900 square feet

ratio = 1cm2 : 36ft2

Step-by-step explanation:

square room

area = 25cm2

1 side =  √ 25

         =  5cm

1cm = 6ft

5cm = 5 x 6

      = 30ft = 1 side

actual area = 30 x 30 = 900ft

ratio = square cm : square feet

       = 25     :     900  ( simplify both ratio )

The triangle in the given image is a right angled triangle.

By Pythagoras theorem,

x² + 12² = ( x + 6 )²

x² + 144 = x² + 36 + 12x

x² - x² = 36 - 144 + 12x

0 = - 108 + 12x

12x = 108

x = 108 / 12

x = 9

Supposed B is the midpoint of line AC. Use the given information to find the missing measure. AB = 6Y -14, BC = 10-2Y 2Y, what is AC

Answers

Given:

B is the midpoint of line AC.

[tex]AB=6Y-14[/tex]

[tex]BC=10-2Y[/tex]

To find:

The length of AC.

Solution:

It is given that B is the midpoint of line AC. So,

[tex]AB=BC[/tex]

[tex]6Y-14=10-2Y[/tex]

[tex]6Y+2Y=10+14[/tex]

[tex]8Y=24[/tex]

Divide both sides by 8.

[tex]Y=\dfrac{24}{8}[/tex]

[tex]Y=3[/tex]

The value of Y is 3.

Now,

[tex]AC=AB+BC[/tex]

[tex]AC=6Y-14+10-2Y[/tex]

[tex]AC=4Y-4[/tex]

Putting [tex]Y=3[/tex], we get

[tex]AC=4(3)-4[/tex]

[tex]AC=12-4[/tex]

[tex]AC=8[/tex]

Therefore, the length of AC is 8 units.

0.73 plus-or-minus 2.58 StartRoot StartFraction 0.73 (1 minus 0.73) Over 45 EndFraction EndRoot

Answers

Answer: Option #1

Step-by-step explanation:

99 % confidence level - so it has to be 2.58 not 2.33 ( thats 98% confidence level )

then 12times facing u out of 45 times .... 12/45= .27

Option #1 :  0.27 +/- 2.58 StartRoot StartFraction 0.27 (1 minus 0.27) Over 45 EndFraction EndRoot

The 99% confidence interval for the true proportion of times the number cube would land with a six facing up is 0.27 plus-or-minus 2.58 StartRoot StartFraction 0.27 (1 minus 0.27) Over 45 EndFraction EndRoot.

What is Confidence Interval?

This is an operation which is used to measure probability that a parameter will fall between a pair of values around the mean

99 % confidence level is closer to 2.58 and 12 times facing up out of 45 times which is 12/45= .27

Hence the reason why option  A was chosen as the most appropriate choice.
