Answer:

y=-x+18

Step-by-step explanation:

Equation of a line

A line can be completely defined by two points. Suppose we know the line passes through points A(x1,y1) and B(x2,y2).

The equation for a line can be written as:

[tex]y=mx+b[/tex]

Where m is the slope and b is the y-intercept. Both values can be determined by using the coordinates of the given points.

First, determine the slope with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The points are: A(15,3) B(3,15)

[tex]\displaystyle m=\frac{15-3}{3-15}=\frac{12}{-12}=-1[/tex]

The equation of the line can be written as:

[tex]y=-x+b[/tex]

Now, use any point to determine the value of b. Substitute (15,3):

[tex]3=-15+b[/tex]

Solve for b:

b=18

The equation of the line is

y=-x+18

The slope is -1 and the y-intercept is 18.

Answer:

Step-by-step explanation:

Answer:

a

 [tex]\sigma = 101.23[/tex]

b

Lower quartile - [tex]M_1 = 66.5[/tex]

Median  - [tex]M = 101[/tex]

 Upper quartile - [tex]M_2 = 128.5[/tex]

c

Standard deviation

Step-by-step explanation:

From the question we are told that

    The data is  

Bristol 93

Cardiff 113

English Agents 77

English O 68

English P 44

English R 109

Glasgow 65

Liverpool 139

London 427

Manchester 189

Newcastle-on-Tyne 118

Scottish 24

Generally the mean is mathematically represented as

     [tex]\= x = \frac{\sum x_i}{n}[/tex]

Here n is the sample with the value  is  12

   So            

=>         [tex]\= x = \frac{93 + 113 + \cdots + 118 + 24}{12}[/tex]

=>         [tex]\= x = 122.92[/tex]

Generally the standard deviation is mathematically represented as

     [tex]\sigma = \sqrt{\frac{\sum (x_i - \= x)}{n} }[/tex]

=>   [tex]\sigma = \sqrt{\frac{(93 - 122.92)^ 2 + (113 - 122.92) + \cdots + (118 -122.92)^2 + (24 -122.92)^2}{12} }[/tex]

=>     [tex]\sigma = 101.23[/tex]

Generally to compute the quartiles we first arrange the data in ascending order

So

Scottish....................24,  

English P ...................44

Glasgow ..................65

English O .................68

English Agents......... 77

Bristol ..........................93

English R.................... 109

Cardiff......................... 113

Newcastle-on-Tyne.. 118

Liverpool..................... 139

Manchester................. 189

London......................... 427

Next we obtain the median

   Looking at data, the median is  

              [tex]M = \frac{93 + 109}{2}[/tex]

=>            [tex]M = 101[/tex]

Next  is to divide the data in between 93 and  109

So the lower  data set is  

 Scottish....................24,  

English P ...................44

Glasgow ..................65

English O .................68

English Agents......... 77

Bristol ..........................93

The median of the lower data set is  

       [tex]M_1 = \frac{65 + 68}{2}[/tex]

       [tex]M_1 = 66.5[/tex]

This median is known as lower  quartile

Considering the second data set

English R.................... 109

Cardiff......................... 113

Newcastle-on-Tyne.. 118

Liverpool..................... 139

Manchester................. 189

London......................... 427

The median of the upper data set is  

     [tex]M_2 = \frac{118 + 139 }{2}[/tex]

=>  [tex]M_2 = 128.5[/tex]

This median is known as upper  quartile

The best measure for describing the spread of the distribution is the standard deviation  because it measure how far each individual data deviates from the mean

Answer:

Step-by-step explanation:

The coded message "&*()" corresponds to the phone number 6789. By matching the symbols with the corresponding keyboard numbers, Satyam's phone number can be decoded.

To decode the coded message and find out Satyam's phone number, we need to match the symbols in the coded message with their corresponding keyboard numbers.

Given the coding system provided, let's decode the coded message:

CODE&*() represents the symbols used in the coded message.

Comparing the symbols with the keyboard numbers, we have:

& corresponds to 6

* corresponds to 7

( corresponds to 8

) corresponds to 9

Therefore, the decoded message translates to the phone number: 6789.

In conclusion, Satyam's phone number, which was coded using the symbols &, *, (, and ), is 6789.

This decoding process involves a simple one-to-one mapping between the symbols and the corresponding keyboard numbers. By identifying the symbols in the coded message and matching them with the appropriate keyboard numbers, we can accurately determine Satyam's phone number.

Find the unit rate, then multiply by 7

Step-by-step explanation:

Find the unit rate

35/5 = 7

Then multiply by the number of songs that we want to download

7*7

You know total time for 5 songs, so find the time for one song, which is the unit rate ( time for one song) then multiply the unit rate by number of songs you want to download.

The answer is:

By finding the unit rate and multiplying it by 7

Answer:

3/4

Step-by-step explanation:

No matter how many pizzas there are, if we divide each pizza to 4 slices, each one gets one slice from each pizza, that is 1/4 of a pizza for each brother. Since there are 3 pizzas, simply multiply 3 x 1/4 = 3/4

Answer:

It depends on the amount of slices

Step-by-step explanation:

It depends on the amount of slices

If there are 8 slices on each pizza, than it's 6 slices per friend. If it's 6, than its 4.5. I assume you mean with 8 slices, so it's 6 slices per friends

Answer: h = 68.5, 51.2

Step-by-step explanation:

Draw a right angle triangle. The base is the sea and the line perpendicular to it is the cliff  

The base is the distance of from boat to the cliff is 104

Let the height of the cliff be h.

The hypotenuse, the distance from the top of the cliff to the boat is therefore 2h-26

Pythagoras tells us that  

(2h−26)^2  = 104^2 + h^2

4h^2 − 52h + 289 = 10816 + h^2

3h^2 − 52h − 10527 = 0

h=68.5, 51.2

The other result is negative and therefore not relevant.

If you cannot factorize then solve using the formula.
