What does 12/27*9/16*32 equal

Answer:

We accept H₀ we don´t have enough evidence to support that the proportion of certain town differs from that of National Information

Step-by-step explanation:

National Information:

p = 10,3 %      p = 0,103

Sample

Sample size    n₁  = 100

x₁  = 8

p₁  = x₁/100         p₁  = 8 / 100     p₁ = 0,08 %  

q₁  =  1 - p₁       q₁  = 1  - 0,08      q₁  = 0,92

Confidence Interval  CI = 95 %   significance level  α  = 5 %   α = 0,05

z(c) for α = 0,05  from z-table is  : 1,64

Test Hypothesis:

Null Hypothesis                                       H₀       p₁  = p

Alternative Hypothesis                           Hₐ       p₁ <  p

The alternative hypothesis suggest a one tail test to the left

z(s)  =  (  p₁  - p ) √p₁*q₁ / n₁

z(s)  = ( 0,08 - 0,103 )/√ 0,08*0,92/100

z(s)  =  - 0,023 / 0,027

z(s)  = - 0,85

Comparing  z(s)   and  z(c)

z(s) > z(c)     - 0,85  > -1,64

z(s) is in the acceptance region, we accept H₀

Step-by-step explanation:

the 3rd angle = 4x+17 because of vertical angles

4x+17 + x+23 + 80 = 180 sum of interior angles of a triangle

5x +40 = 100

5x = 60

x = 12

angle A = x + 23 = 12 +23 = 35

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:

Sample space is 36C4

Now, we want to know all of the combinations that have 1 digit in it.

So, we can have one here:

1XXX

X1XX

XX1X

XXX1

But we have 10 different digits to choose from. So, we need to introduce the combination term, nCr, where n is a list of all digits and r is how many we want.

Since we only want one, we will need 10C1 for the number of digits. But we need to choose three lowercases, so it becomes 10C1 × 26C3

Since it's a probability question, we need to divide that by our sample space, 36C4, and our percentage becomes 44%

Answer:

28%

Step-by-step explanation:

It is not 44%. I put that and it was wrong.

Answer:

2.2 : 1

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 :

11 : 5

In the form n : 1

divide both sides by 5

11/5 : 5 /5

2.2 : 1

Answer:

27 > q

Step-by-step explanation:

Solving an algebraic inequality is very similar to solving an algebraic equation, one uses inverse operations. One major difference between the two is that when one multiplies or divides an algebraic inequality by a negative number, one must remember to flip the inequality sign.

55 - 5q > 4 ( 7 - q )

Distribute,

55 - 5q > 28 - 4q

Inverse operations,

55 - 5q > 28 - 4q

     +5q          +5q

55 > 28 + q

-28  -28

27 > q

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

__

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°

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%.

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.
