Explain the difference between a public and Private company. is it better for a company to be public or private

I'll do problem 3 to get you started.

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

Part 1) Finding the mean:

The mean is found by adding up all the numbers and dividing by n, where n is the number of items in the set.

We sum the numbers to:

5+8+5+9+6+15+9+3+8+7+10+12 = 97

Then we divide over n = 12

mean = sum/n = 97/12 = 8.083333 approximately

This rounds to 8.08

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

Part 2) Finding the standard deviation:

I'm assuming your teacher is talking about the population standard deviation, as opposed to the sample standard deviation.

First subtract each value from the mean. It helps to make a table as shown in the attachment below.

Column A is the original data set. Column B is when we subtract each data item x from the mean M.

Column C is where we square each item in column B.

Adding up everything in column C leads to 118.916666666667 which is approximate. This value is highlighted in the table diagram. Divide this over n = 12 to get 9.90972222222222 which is also approximate

The last step is to apply the square root to that and we get 3.1479711279

This rounds to 3.15

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

Part 3) Finding the min:

From here on out, we have fairly simple calculations and don't need to involve a spreadsheet or any complicated formulas.

The min value is the smallest value of the set. So that would be 3

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

Part 4) Finding the value of Q1, first quartile:

Sort the items in ascending order, ie from smallest to largest.

You should get this set: {3, 5, 5, 6, 7, 8, 8, 9, 9, 10, 12, 15}

There are n = 12 items here, so the median is between slot 12/2 = 6 and slot 7. The values in slot 6 and 7 are the two copies of '8'. That must mean the median is (8+8)/2 = 8.

Now break up the set into two equal halves

L = {3, 5, 5, 6, 7, 8} = lower half of six items

U = {8, 9, 9, 10, 12, 15} = upper half of six items

The median of set L is exactly the value of Q1, so that would be (5+6)/2 = 11/2 = 5.5; note how this is exactly between the two middle most values of 5 and 6.

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

Part 5) Finding the median:

We found that earlier in part 4. The median is 8.

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

Part 6) Finding the value of Q3, third quartile:

Focus on set U = {8, 9, 9, 10, 12, 15}, which was the upper set of values, ie values larger or equal to the median.

The middle two values here are the '9' and '10'. The median is at the midpoint of these values: (9+10)/2 = 19/2 = 9.5

We have Q3 = 9.5

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

Part 7) Finding the max:

The max is the largest item in the original set

Refer to the sorted set {3, 5, 5, 6, 7, 8, 8, 9, 9, 10, 12, 15} and we see that 15 is the max.

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

Part 8) Finding the IQR (interquartile range):

Subtract the values of Q3 and Q1 to get the IQR

IQR = Q3 - Q1

IQR = 9.5 - 5.5

IQR = 4

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

Part 9) Finding the range:

The range is a similar idea as the IQR; however, we'll subtract the max and min this time.

Range = max - min = 15 - 3 = 12

The range is 12.

The range, IQR and standard deviation all help us determine the spread of the data. The larger the value gets, the more spread out the data is.

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

Summary:

Side note: The phrase "five number summary" refers to the five values of: min, Q1, median, Q3, max. All of which are needed to form a box-and-whisker plot.

Answer:

5y + 2x + 15

Step-by-step explanation:

x+y+x+y+3(y + 5)

Open the bracket.

x + y + x + y + 3y + 15

Bring the like terms together and simplify them.

3y + y + y + x + x + 15

= 5y + 2x + 15

Answer:

First let's calculate the area of the bottom part

diameter is 34 m

so the radius (r) is 1/2 * 34 m = 17 m

bottom part is 1/2 of a circle

circle surface area formula is πr²

so surface area of our bottom part is 1/2 * πr²

1/2 * πr² = 1/2 * 3,14 * 17² = 453,73

so it's 453,73 m²

Triangle part consists of 2 smaller rectangular triangles

surface area for rectangular triangle is 1/2 * a * h

in our case a = r = 17 m and h = 30m

so one smaller rectangular triangle is 1/2 * r * h = 1/2 * 17 * 30 = 255

so it's 255 m²

and because our entire triangle part consists of 2 smaller rectangular triangles it's area is 2 * 255 m² = 510 m²

Surface area of the entire figure is a sum of 510 m² and  453,73 m²

510 m² +  453,73 m² =  963,73 m²

Answer:

The 4/6 square yard cover less area than 1 square yard.

Step-by-step explanation:

If you simplify [tex]\frac{4}{6}[/tex], it'll equal to [tex]\frac{2}{3}[/tex] which is the same as 0.6 with a bar on top of 6. 0.6 with a bar on top of 6 is less than 1.

The 0.6 with a bar on top of 6 is less than 1.

To compare the given problem.

Simplification means simplifying processes involved in work towards consistency of efforts, costs and time. It eliminates useless and disadvantageous (or unnecessary) diversity and variety.

Given that:

Simplify 4/6, it’ll equal to 2/3 which is the same as 0.6 with a bar on top of 6.

0.6 with a bar on top of 6 is less than 1.

So, the 0.6 with a bar on top of 6 is less than 1.

Step-by-step explanation:

Let b represent the base of the triangle in meters. Then the height is ...

  h = 3 +2b

and the area is ...

  A = 1/2bh

  8 = 1/2(b)(3 +2b)

  16 = 3b +2b^2 . . . . . . . multiply by 2 and eliminate parentheses

  2(b^2 +3/2b + (9/16)) = 16 + 9/8 . . . . . . complete the square

  2(b +3/4)^2 = 17.125

  (b +3/4)^2 = 8.5625 . . . . . divide by 2

  b + 0.75 = √8.5625 ≈ 2.9262

  b = -0.75 +2.9262 = 2.1762

  h = 3 +2b = 7.3523

The base is about 2.18 meters and the height is about 7.35 meters.

Answer:

It takes 10 fewer minutes for Noah than for Charlotte to home from school each day.

Step-by-step explanation:

We use the following relation to solve this question:

[tex]v = \frac{d}{t}[/tex]

In which v is the velocity, d is the distance, and t is the time.

Finding the distance:

Charlotte walks home from school every day at a rate of 4 miles per hour. It takes her 30-minutes to reach home.

This means that [tex]t = 0.5, v = 4[/tex]. Time is 0.5 because as the velocity is in miles per hour, the time has to be in hours. We use this to find d.

[tex]v = \frac{d}{t}[/tex]

[tex]4 = \frac{d}{0.5}[/tex]

[tex]d = 4*0.5 = 2[/tex]

The distance is of 2 miles.

Her brother, Noah, runs home from the same school every day at a rate of 6 miles per hour.

We have to find t, in hours, for which [tex]v = 6, d = 2[/tex]. So

[tex]v = \frac{d}{t}[/tex]

[tex]6 = \frac{2}{t}[/tex]

[tex]6t = 2[/tex]

[tex]t = \frac{1}{3}[/tex]

A third of an hour. In minutes, this is a third of 60, that is 60/3 = 20 minutes.

How many fewer minutes does it take Noah than Charlotte to reach home from school each day?

Noah: 20 minutes

Charlotte: 30 minutes

30 - 20 = 10

It takes 10 fewer minutes for Noah than for Charlotte to home from school each day.

Answer:

A.  y = |x + 4| - 2.

Step-by-step explanation:

The graph of y = |x| is V shaped and passes through the origin and the slope  is 1 (like the given graph).

y = |x + 4) moves the V shaped graph 4 units to the left so the tip of the V is at x = -4.

Now subtracting 2 from this graph will bring the graph to the point where x = -4 and y = -2.

So the given function is y = |x + 4| - 2.

Step-by-step explanation:

I was using 6×8 rectangle as a base of the triangular prism (as shows on the picture.

Let use the definition of a triangular prism and LSA = (5 + 5 + 6) × 8 = 128 cm²

The lateral surface area of the triangular prism is 128 square cm.

A triangular Prism is a pentahedron. It is a 3-D shape with two identical faces in the shape of a triangle connected by three rectangular faces. The edges and vertices of the bases are joined with each other via three rectangular sides.

For the given situation,

The sides of the triangle are 5 cm, 6 cm, 5 cm.

The length of the prism = 8 cm

The formula for lateral surface area of triangular prism is

[tex]LSA=(perimeter)(length)[/tex]

On substituting the above values,

⇒ [tex]LSA=(5+6+5)(8)[/tex]

⇒ [tex]LSA=(16)(8)\\[/tex]

⇒ [tex]LSA=128[/tex]

Hence we can conclude that the lateral surface area of the triangular prism is 128 square cm.

Answer:  1) 70°  2) x = 55

Step-by-step explanation:

1) If m∠1 = 70°,then m∠8 = 70°.

Because m∠8 is the vertical angle of m∠5, and m∠5 is the corresponding angle of m∠1, which means that m∠8 = m∠1 = 70°. And also m∠1 and m∠8 are alternate exterior angles, they equal to each other.

2) m∠4 = 70°, and m∠7 = 2x, then m∠4 + m∠7 = 180°,because they are consecutive interior angles.

m∠4 + m∠7 = 180°

70 + 2x = 180

2x = 110

x = 55
