Answer:

[tex]N:D = 1: 2[/tex]

Step-by-step explanation:

Given

Represent Nickels with N and Dimes with D

[tex]N=25[/tex]

[tex]D=25[/tex]

Required

Write as a ratio to lowest term

Ratio of Nickels to Dime is represented as N:D

[tex]N:D = 25\ nickels : 25\ dimes[/tex]

Convert nickels to dollar

[tex]N:D = 25\ * \$0.05. : 25\ * \$0.10[/tex]

[tex]N:D = 1.25 : 2.5[/tex]

Divide through by 1.25

[tex]N:D = 1.25/2.25 : 2.5/1.25[/tex]

[tex]N:D = 1: 2[/tex]

Hence, the ratio to lowest term is 1:2

If you think about it it's basically a addition problem.

Answer:

The difference between 4 is –92 is 132

Answer:

Given - The difference between two- third of a no. and 4 is (-92)

Let the no. be X

TO Find - The no.

Solution -

Let the no. be X

Two - third of a no. = 3/2x

according to the question equation made is-

2/3x - 4 = (-92)

2/3x = (-92)+ (4)

2/3x = ( -88)

X = (-88) × 3/2

X= ( -264/2)

X = (-132)

Problem 1

Answers:

------------------------

Explanation:

Imagine a fan blade rotating. As it rotates really quickly, it occupies a 3D space. Or perhaps imagining rotating eggbeaters is a better thing to have in mind. Those blades spin really fast to form a 3D shape. So that's what's going on with this problem. If you spin a triangle around an axis, a cone will form. The base of the triangle forms the base of the cone. Half the base of the triangle is the radius of the cone. The height of the triangle is the height of the cone.

Similarly, a rectangle rotated around its center axis forms a cylinder. Think of a revolving door. That's often a classic example. Finally, a circle spun around any of its diameters will form a sphere.

========================================================

Problem 2

Answers:

-------------------------------

Explanation:

Pick objects around your house that are fairly simple in design and resemble either a cylinder, sphere, or cone. A cup resembles a cylinder just it doesn't have a top to it. A ball is a 3D sphere that has an interior to it, unless the ball is filled with air. A funnel resembles a cone due to its triangular shape of sorts. A paper towel roll (the card board piece or the cardboard plus the actual paper towels) resemble a cylinder as well. You can pick any four other objects you have around your house such as a cylindrical speaker, batteries (shaped as a cylinder), soup cans (also cylinders), and so on.

========================================================

Problem 3

Answers:

-------------------------------

Explanation:

These formulas are what you should memorize or have handy on a flashcard. It is possible to derive them, but it would require calculus to do so. Also, such a process is quite length. So memorization or flashcards are the better way to go.

For the cylinder and cone, r is the radius and h is the height. Note how the formulas are nearly identical except the cone has the (1/3) term. This shows that the cone's volume is 1/3 that of the cylinder's volume where they both have the same radius r and height h.

The sphere also deals with the radius r, but we don't have to worry about the height of the sphere (it's really just 2r).

For the pyramid, L,W,H represent the length width and height respectively. The length and width form the base of the pyramid. Recall that L*W*H is the volume of a rectangular block. The volume of a pyramid is 1/3 of that rectangular block's volume.

If all of a 2D object's sides and angles have different lengths, such shape is said to be irregular.

In geometry, a form or figure having length and breadth is referred to as a "2D shape." Due to the lack of a thickness, a third dimension, such as the case of a prism or a cube, two-dimensional or 2D objects are often measured in terms of their two faces.

'2D' refers for 2-dimensional. A 2D shape is any form that has two dimensions. Consider for a moment what it means to have two dimensions. We could only move backwards or forwards in a straight line if we only had one dimension to work with. One dimension is a line.

Cone: Triangle

Cylinder: Rectangle

Sphere: Circle

Therefore, if all of a 2D object's sides and angles have different lengths, such shape is said to be irregular.

Answer:

The man in the goose cross the river, with the fox and the beans together, he leaves the goose on the other side and goes back across.

The man then takes the fox across the river, and since he can’t leave the fox in the goose together, he brings that goose back.

Again, since the goose and the beans can’t be left together, he leaves the goose and he takes the beans across and leaves with the fox.

He returns to pick up the goose and heads back across the river one last time.

Answer:

  9 square units

Step-by-step explanation:

The base JL is a horizontal line. Its length is 5-(-1) = 6.

The height is the difference between the y-coordinate of K and the y-coordinate of the horizontal line: 4 -1 = 3.

The formula for the area of a triangle is ...

  A = (1/2)bh

  A = (1/2)(6)(3) = 9 . . . square units

The area of ∆JKL is 9 square units.

Answer:

a

The 95% confidence interval is

   [tex] 0.7811 <  p <  0.9529 [/tex]

Generally the interval above can interpreted as

    There is 95% confidence that the true proportion of Wal-Mart stores that have more than 2 items priced inaccurately per 100 items scanned lie within the interval  

b

  Generally  99% is outside the interval obtained in a  above then the claim of Wal-mart is not believable  

c

 [tex] n =  125  \  stores [/tex]  

Step-by-step explanation:

From the question we are told that

    The sample size is  n =  60  

    The number of stores that had more than 2 items price incorrectly is  k =  52  

Generally the sample proportion is mathematically represented as  

             [tex]\^ p = \frac{ k }{ n }[/tex]

=>          [tex]\^ p = \frac{ 52 }{ 60 }[/tex]

=>          [tex]\^ p = 0.867[/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  [tex]\frac{\alpha }{2}[/tex] 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{ 0.867  (1- 0.867)}{60} } [/tex]

=>   [tex]E =  0.0859  [/tex]

Generally 95% confidence interval is mathematically represented as  

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

=>    [tex] 0.867  - 0.0859  <  p <  0.867  +  0.0859 [/tex]

=>    [tex] 0.7811 <  p <  0.9529 [/tex]

Generally the interval above can interpreted as

    There is 95% confidence that the true proportion of Wal-Mart stores that have more than 2 items priced inaccurately per 100 items scanned lie within the interval  

Considering question b

Generally  99% is outside the interval obtained in a  above then the claim of Wal-mart is not believable  

Considering question c

From the question we are told that

    The margin of error is  E = 0.05

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  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.645[/tex]

Generally the sample size is mathematically represented as  

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

=> [tex]n=  [\frac{1.645 }}{0.05} ]^2 * 0.867  (1 - 0.867 ) [/tex]

=>   [tex] n =  125  \  stores [/tex]
