What is 1000% percent of 99.

Answer:

Decision rule

   Reject null hypothesis

Conclusion

There is significance evidence that the true mean is different from 0.86

Step-by-step explanation:

From the question we are told that

  The population mean   [tex]\mu  = 0.86[/tex]

   The  sample is  mean is [tex]\=  x  =  0.8708[/tex]

  The standard deviation is  [tex]\sigma =  0.0068[/tex]

The  level of significance is  [tex]\alpha  =  0.01[/tex]

  The  sample size n =  3

The null hypothesis is  [tex]\mu =  0.86[/tex]

The alternative hypothesis  is [tex]\mu \ne  0.86[/tex]

Generally the test statistics is mathematically represented as  

    [tex]z =  \frac{\=  x  - \mu }{ \frac{\sigma}{\sqrt{n} } }[/tex]

=> [tex]z =  \frac{ 0.8708 - 0.86 }{ \frac{0.0068}{\sqrt{3} } }[/tex]

=>  [tex]z =  2.751  [/tex]  

Generally  p- value is mathematically represented as

       [tex]p-value =  2 P(z >2.751   )[/tex]

From the z-table  

        [tex]P(z >2.751 ) =  0.0029707[/tex]

So

     [tex]p-value =  2 *  0.0029707[/tex]

=>   [tex]p-value =  0.00594 [/tex]

From the obtained question we see that  [tex]p-value  <  \alpha[/tex]

Hence we reject the null hypothesis

Answer:

Step-by-step explanation:

If a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, in order to determine the number of whole cheese sandwiches that can be prepared from 44 slices of bread and 69 slices of cheese, we will use the equality postulate as shown;

1 cheese sandwich = 2 slices of bread

x cheese sandwiches = 44 slices of bread

cross multiply

2 * x = 1 * 44

2x = 44

divide both sides by 2

2x/2 = 44/2

x = 22

Similarly;

1 cheese sandwich = 3 slices of cheese

y cheese sandwiches =  69 slices of cheese

cross multiply

3 * y = 1 * 69

3y = 69

divide both sides by 3

3y/3 = 69/3

3y = 23

Since both values of x and y are greater than or equal to 22 hence 22 sandwiches can be prepared from 44 slices of bread and 69 slices of cheese.

Since the amount of cheese sandwiches made from slices of bread (22) is not up to that made from slices of cheese (i.e 23), hence the ingredient that limits the number of sandwiches that can be made is the slice of bread

Answer:

Step-by-step explanation:

parallel angles are equal

3x + 21 = 6x - 60

combine similar terms:

3x - 6x = -60 - 21

-3x = -81

x = 81/3

x = 27

now, plugin the value of x=27 back into the equation to get the angle:

= 3x + 21

= 3(27) + 21

= 102

= 6x - 60

= 6(27) - 60

= 102

as you noticed, both values are equal 102 = 102 because its a parallel angles

so the equation is 3x + 21 = 6x - 60

Answer:

63 men said no.

Step-by-step explanation

3/5 * 2/2 = 6/10, 6/10 - 3/10 (women) = 3/10 meaning 7/10 men said no. 90*1.7 = 153, 153-90=63

Answer:

30%. Remember the question is what percentage?

Step-by-step explanation:

Given Informations:

Men = 90

Women = 60

Total number (men + women) = 150.   ...... (1)

For Yes Members,

3/5 of the people said YES.

3/5 of 150 = 90 .......                                        (2)

This means that out of 150, 90 people said YES.

However, we dont know what ratio are men or women all we can deduce is that 90 said YES.

From the question, 3/10 are women that said YES.

Meaning 3/10 of 90 are women = 27. ..                  (3)

27  women said YES therefore

90 -27 = 63  Men said YES.

FOR NO Members,

If 90 out of 150 said yes, then 60 said NO.

However, we dont know the ratio of Men and Women that said NO. What we can do is to solve it from the known to the unknown.

For Men,

The total number is 90.

63 said YES, therefore (90 - 63 ) definitely said NO.

= 27 Men said NO                         (4)

For Women,

The total number of women is 60

27 said YES, Therefore (60 - 27) said NO

= 33 women said NO.      ( 5)

The question is what percentage of Men said NO?

Percentage =

number of men that said NO / The total number of Men  * 100

= 27/90 * 100

=30%

To Prove the Answer

If you agree with Eq 2, which says 90 people said yes. Therefore, (150 -90) = 60 said NO.

Remeber the 60 is inclusive of Men and Women.

Let's see, if we will get 60 when we add the number of men and women we got that said NO.

Add the value in Eq 4 + Eq 5.

27 + 33 = 60.

Step-by-step explanation:

16. d-4 = -7

or, d = -7+4

or, d = -3

therefore, d = -3.

17. c-34 = 20

or, c = 20+34

or, c = 54

therefore, c = 54

18. a-4 = -18

or, a = -18 + 4

or, a = -14

therefore, a = -14

19. r-3 = 8

or, r = 8+3

or, r = 11

therefore, r = 11

20. z-100 = 100

or, z = 100+100

or, z = 200

therefore, z = 100

21. 5 = d - 1

or, 5+1 = d

or, 6 = d

or, d = 6

therefore, d = 6

Answer:

  1.  see the first attachment for a graph; quadrants I, II, III; vertex (-3, -4); x-intercepts -5, -1; graph is dashed line, shaded inside the parabola, which opens up

  2.  see the second attachment for a graph; all quadrants; vertex (1, 2); x-intercepts 1±√2; graph is a solid line, shaded outside the parabola, which opens down; (-7, 0) is a solution

Step-by-step explanation:

1. The boundary expression is in vertex form, so the vertex can be read directly.

  y = (x -h)^2 +k . . . . . . parabola with vertex (h, k)

  y > (x +3)^2 -4 . . . . .  (h, k) = (-3, -4)

The leading coefficient is +1, a positive number, so the parabola opens up. The relation is y > ( ), so values of y above the dashed line will be shaded. Those values are inside the parabola. The points (0, 0) and (-7, 0) are not in the shaded area, so are not solutions.

__

2. Again, the boundary expression is in vertex form, so the vertex can be read directly.

  y ≥ -(x -1)^2 +2 . . . . . (h, k) = (1, 2)

The x-intercepts are found by solving for x when y=0:

  0 = -(x -1)^2 +2

  x -1 = ±√2

  x = 1±√2

The leading coefficient is -1, so the parabola opens downward. The relation is y ≥ ( ), so y-values above the solid line will be shaded. Those values are outside the parabola. Point (0, 0) is not a solution. Point (-7, 0) is a solution.

Additional comment

As with the graph of any inequality, the boundary line is solid when the "or equal to" case is part of the relation. If the relation is strictly "greater than" or "less than", then the boundary line is dashed.
