What is 5.56666666667 as a fraction?

To write 5.56666666667 as a fraction you have to write 5.56666666667 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

5.56666666667 = 5.56666666667/1 = 55.6666666667/10 = 556.666666667/100 = 5566.66666667/1000 = 55666.6666667/10000 = 556666.666667/100000 = 5566666.66667/1000000 = 55666666.6667/10000000 = 556666666.667/100000000 = 5566666666.67/1000000000 = 55666666666.7/10000000000 = 556666666667/100000000000

And finally we have:

5.56666666667 as a fraction equals 556666666667/100000000000

Complete Question

The data for this question is shown on the first uploaded image

Answer:

The 95% confidence interval estimate of the population percentage is  

   [tex] 33.2\% <  p < 76.8 \% [/tex]

Step-by-step explanation:

On the data the first value is the height of the president while the other value is the height of his opponent

    The sample size is  n  =  20  

Looking at the data we see that out of the 20  presidents that only 11 is taller than their opponent

 So the proportion of presidents that are taller than their opponents is  

      [tex]\^ p = \frac{11}{20}[/tex]  

=>   [tex]\^ p = 0.55[/tex]

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of   is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

   [tex]E = Z_{\frac{\alpha }{2} } *  \sqrt{\frac{\^ p (1- \^ p) }{n}} [/tex]

  [tex]E = 1.96 *  \sqrt{\frac{0.55 (1- 0.55) }{20}} [/tex]

   [tex]E = 0.218[/tex]

Generally 95% confidence interval is mathematically represented as  

      [tex]\r p -E <  p <  \r p +E[/tex]

=>    [tex]0.55-0.218 <  p < 0.55+ 0.218 [/tex]

=>    [tex]0.332 <  p < 0.768 [/tex]

Converting to percentage

        [tex](0.332*100)\% <  p < (0.768 *100) \% [/tex]

=>    [tex] 33.2\% <  p < 76.8 \% [/tex]

Answer:

Ok so right now that is in standard form (Ax+by=C) and we want to get this into y=mx+b form so that we can easily identify the slope. To do that we need to get y alone by folowing these steps:

9x-3y=81

9x-9x-3y=81-9x (in this step we are just getting rid of the x's from the left side so we can get y alone but since we subtract x from that side we need to subtract the same amount of x's on the other)

-3y=81-9x

-3y/-3=81-9x/-3 (finally to get y alone we need to divide by a -3. This is because any negative number multiplied or divided by another negative will give us a positive. If we divide by 3 then y will be negative which is incorrect. We have to divide by -3 on each side)\

y=81-9x/-3 -----> y=-27+3x ( in this part we have to divide everything on the right side of the equation by -3 as we did on the left side. 81/-3 = -27 and -9x/-3 = +3x.

our new equation is y=-27+3x although the proper form is y=mx+b.

all we need to do now is flip the 3x and -27 for this equation to match y-mx+b form. M in the equation represents the slope of an equation.

y=-27+3x---> y=3x-27

in this equation 3 is m and m represents the slope. For an line to be parralel to one another they must have the same slope. Therefore the slope of a line parallel to that equation is 3.

Step-by-step explanation:

The Slope of a line parallel to the line whose equation is 9x – 3y = 81 is 3.

A slope of a line is the change in y coordinate with respect to the change in x coordinate.

Given that the slope of a line parallel to the line whose equation is

9x – 3y = 81

Reducing the Equation in form of y = mx + c, where m is the slope,

9x - 3y = 81

3y = 9x - 81

y = 3x - 27

Since, two line when parallel have equal slope, so the slope of the given line is 3.

Hence, The Slope of a line parallel to the line whose equation is

9x – 3y = 81 is 3.

Answer:

The direction matters  , but only in sign... so from A to A'  is what i'm guessing is the direction of translation

Step-by-step explanation:

find the vector from A to A'  or any of the other non prime to prime points.. the vector will be the same...  soooo

take the origin point as P1 , then take the destination point a P2

and subtract P2-P1

P2 = A' = (6,-2)

P1 = A = (2, 1)

(6-2, -2-1) = (4,-3)

your vector can be place at the origin.. and go 4 in the x direction and -3 in the y direction and you get that translation.. make sense?

Answer: 4 more wrenches than screwdrivers.

Step-by-step explanation: 6 + 8 = 14. 14 > 10 by 4.

The correct option is A. Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

There are four types of rigid motions that we will consider translation , rotation, reflection, and glide reflection.

Here we have to rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

Hence option A is correct that is Rotate GHJ using center G until GH is lined up with ST and then reflect over a line halfway between G'H'J' and STU.

Answer:

864 inches

Step-by-step explanation:

12*3=36

36*24=864

A sewing kit includes a spool that holds 864 inches of thread.

Given that,
A sewing kit includes a spool that holds 24 yards of thread, how many inches of thread does the spool hold is to be determined.

All over the world, most things are in use as of common quantity, so people all over the world agree that they have to follow a common system of measurement and that the common system of measurement is called standard measurement.

here,
1 yard = 3, 1 foot = 12 inches
So,
24 yard = 24 [3] feets
24 [3] feet = 24 [3] [12] inches = 864 inches

Thus, A sewing kit includes a spool that holds 864 inches of thread.

Step-by-step explanation:

Six

6

Times the quantity of four

(4)

Plus a number

+n

The phrase that best represents six times the quantity of four plus a number is 6(4) + n.

A numerical expression is a form where we express a statement by number and their operations.

According to the given phrase six times the quantity four which is 6(4) plus a number.

6(4) + n.

What we have done here is we formed a numerical expression from a given statement.

Suppose we have given sum of 4 and thrice of a number is 10.

So, 4 + 3n = 10

3n = 10 - 4

3n = 6

n = 2.

So the number is 2.
