Answer:

  a = 8; b = -9

Step-by-step explanation:

Filling in the given values gives you two equations.

  7 = a(2) +b

  -1 = a(1) +b

Subtracting the second equation from the first gives ...

  (7) -(-1) = (2a +b) -(a +b)

  8 = a . . . . . simplify

Using this value in the first equation gives ...

  7 = (8)(2) +b

  b = 7 -16 = -9

The constants are a = 8, b = -9.

Step-by-step explanation:

[tex]We\ are\ given\ that,\\Total\ number\ of\ Black\ Socks=7\\Total\ number\ of\ White\ Socks=12\\Total\ number\ of\ Navy\ Socks=4\\Hence,\\Total\ number\ of\ Socks\ Parker\ has=12+4+7=23\\We\ know\ that,\\The\ Random\ experiment\ here,\ is\ pulling\ out\ a\ white\ sock,\ after\ pulling\\ a\ black\ sock.\\Hence,\\Since\ the\ Black\ Sock\ had\ been\ removed\ from\ his\ drawer,\ the\\ number\ of\ 'Socks'\ that\ remain\ in\ his\ drawer=23-1=22\\[/tex]

[tex]Hence,\\Total\ elementary\ events\ for\ this\ random\ experiment=22\\Now,\\We\ just\ need\ to\ find\ out\ the\ probability\ of\ pulling\ out\ a\ 'White\ Sock'.\\Hence,\\Number\ of\ White\ socks=12\\Hence,\\Favorable\ number\ of\ elementary\ events\ for\ the\ Random\ Experiment=12[/tex]

[tex]We\ also\ know\ that,\\Probability\ for\ an\ Event\ A=\frac{Favorable\ No.\ of\ Elementary\ Events}{Total\ no.\ of\ elementary\ events}[/tex]

Answer:

  a) v = 3i -6j

  b) v ≈ 6.708∠-63.43°

  c) w = -32.627i +15.214j

  d) v+w = -29.627i +9.214j = 31.027∠162.72°

Step-by-step explanation:

Most graphing calculators and many scientific calculators can do arithmetic with vectors, often in the form of complex numbers or arrays. Of course, the usual conversions can be used:

  (r; α) ⇒ (r·cos(α), r·sin(α))

  (x, y) ⇒ (√(x²+y²); atan2(x, y))

where atan2(x, y) is arctan(y/x) quadrant-adjusted for the signs of x and y

The first attachment shows the vectors and their sum in component form as complex numbers. For your purpose, the translation is ...

  a +bi ⇒ ai +bj

The second attachment shows the vectors and their sum in polar form (magnitude and direction). I like the A∠B format. You may translate it to whatever form you need, for example, (A; B), A·cis(B), A(cos(B)i +sin(B)j), Ae^(iB), or any other. (The "semicolon format" is used by at least one app to distinguish between rectangular coordinates (a, b) and polar coordinates (A; B).) The angles here are in degrees (not radians), matching the form in the problem statement.

Answer:

The probability of getting two 4s is 5.55%.

Step-by-step explanation:

Since fair says is rolled four times, to calculate the probability of obtaining exactly two 4s the following calculations must be performed:

100/6 = 16.6666

0.166666 x 0.166666 = X

0.02777 = X

1 = 100

0.02777 = X

0.02777 x 100 = X

2.77 = X

2.77 x 2 = 5.55

Therefore, the probability of getting two 4s is 5.55%.

Step-by-step explanation:

cube root 1331 : reciprocal of 0.2

give your answer in the form n:1

The cube root of 1331

(1331)^1/3 = 11

Reciprocal of 0.2 = 1 /0.2 = 5

Hence, the ratio Can be expressed as :

Answer: The domain is in the picture

Step-by-step explanation:

Answer:

1a) UCL = 14.2

    LCL = 10.9

b) UCL = 15.63

    LCL = 9.37

c) UCL = 16.48

   LCL = 8.52

2) The difference between the limits falls close together as n increases

and the difference between the limits  falls farther away from 12.5

Step-by-step explanation:

mean ( μ ) = 12.5

std ( б ) = 1.1

UCL = μ + ( n - 1 ) б / √n

LCL = μ - ( n - 1 ) б / √n

1) a) Given  n = 4

UCL = 12.5 + ( 3 ) * 1.1 / 2

       = 12.5 + 3.3/2 = 14.15 ≈ 14.2

LCL = 12.5 - 3.3/2 = 10.85 ≈ 10.9

b) Given n = 10

UCL = 12.5 + ( 9 ) * 1.1 /√10

       = 12.5 + 3.13 = 15.63

LCL = 12.5 - 3.13 = 9.37

c) Given n = 15

UCL = 12.5 + 14 * 1.1 / √15

       = 12.5 + 3.98 = 16.48

LCL = 12.5 - 3.98 = 8.52

2) As the sample size increases the difference between the limits of the control chart decreases

Hence the difference falls close together as n increases

and the difference between the limits  falls farther away from 12.5

Answer:

Step-by-step explanation:

Let w represent the width of the rectangle. Then w+11 is the length. The perimeter is given by ...

  P = 2(L +W)

  182 = 2((w+11) +w)

  182 = 4w +22 . . . . . simplify

  160 = 4w . . . . . . . . . subtract 22

  40 = w . . . . . . . . . . . divide by 4

  40 +11 = length = 51 . . . . determine length

The dimensions of the rectangle are 40 × 51 units.

__

The area of the rectangle is ...

  A = LW

  A = (51)(40) = 2040 . . . . square units

The area is 2040 square units.

_____

Additional comment

The perimeter of a rectangle is double the sum of length and width, so that sum is 182/2 = 91 units. Now, this is a "sum and difference" problem, where the sum of length and width is 91, and the difference is 11. The solutions to such a problem are half the sum and half the difference of these numbers. Above, we found the smaller dimension (width) first: (91-11)/2 = 40. We could have found the length as (91+11)/2 = 51. The knowledge of the general solution to "sum and difference" problems often lets you work them with mental arithmetic.
