Suppose the consumer group used a sample size of 50 instead of 100 for each airline. When all other things remain the same, what effect would the decrease in sample size have on the interval?

it is one cause the wall is circular

Answer: 1

Step-by-step explanation: the wall is circular, it doesn’t has a space

Mary got 9.37%. discount .

Given ,

             discount = 11%

So,

        ((8000x0.110) + (17000x0.086)) = 2342

           ⇒     2342 / (8000+17000) = 2342/25000

                                    = 0.0937 or 9.37% discount.

The percentage discount allowed all together was 9.37%.

Answer:

12+hd

Step-by-step explanation:

Answer:

Rule : When we rotate a figure of 90 degrees clockwise, each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure. Let us look at some examples to understand how 90 degree clockwise rotation can be done on a figure.

1 Answer. No, it is not possible. If you have a rectangle that is 2 units tall and 1 unit wide, it will be the same way up after a horizontal or vertical reflection. You can rotate a rectangle through 90 degrees using 2 reflections, but the mirror line for one of them should be diagonal.

Answer:

3/20

Step-by-step explanation:

Fabric left over = total fabric purchased - total fabric used to make a tote bag

total fabric used to make a tote bag = [tex]4\frac{2}{8}[/tex] × [tex]\frac{1}{5}[/tex] =

[tex]\frac{34}{8}[/tex] × [tex]\frac{1}{5}[/tex] = [tex]\frac{34}{40}[/tex]

fabric left over = 1 - 34/40

40 / 40 - 34/40  = 6 /40

To transform to the simplest form. divide both the numerator and the denominator by 2

3/20

The figure is a parallelogram so the facing sides have equal size which means :

DE = GF & DG = EF

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

DE = 3x - 1 , GF = 2x + 11

DE = GF ==》 3x - 1 = 2x + 11

subtract sides minus 2x

==》- 2x + 3x - 1 = - 2x + 2x + 11

collect like terms

==》 x - 1 = 11

add sides 1

==》 x - 1 + 1 = 11 + 1

==》 x = 12

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

As we found : DG = EF

DG = 2x - 3 So EF = 2x - 3

To find the size of EF, we need to put the value of x (which we found above) instead x.

EF = 2 × ( 12 ) - 3 ==》 EF = 24 - 3

==》 EF = 21

And we're done...

There's a theorem for this: the angle made by two intersecting secants of a circle has a measure equal to half the difference of the arcs the secants intercept. In this case,

x = (130° - 30°) / 2 = 50°

Answer:

(- 1, 2 )

Step-by-step explanation:

Given the 2 equations

x + 2y = 3 → (1)

3x + 5y = 7 → (2)

Multiplying (1) by - 3 and adding to (2) will eliminate the x- term

- 3x - 6y = - 9 → (3)

Add (2) and (3) term by term to eliminate x

0 - y = - 2

- y = - 2 ( multiply both sides by - 1 )

y = 2

Substitute y = 2 into either of the 2 equations and solve for y

Substituting into (1)

x + 2(2) = 3

x + 4 = 3 ( subtract 4 from both sides )

x = - 1

solution is (- 1, 2 )

(2,1)

Answer:

$67.25

Step-by-step explanation:

52.60 x 8%  = 52.60 x 0.08 = 4.21

52.60 x 20% = 52.60 x 0.20 = 10.44

52.60 + 4.21 + 10.44 = 67.25

Answer:

The slope is 1

Step-by-step explanation:

(0-7)/(-10+3)=

-7/-7= 1

Answer:

m  =  1

Step-by-step explanation:

Slope is:

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

We are given the points (-3, 7) and (-10, 0).

[tex]\frac{0-7}{-10-(-3)}=\frac{-7}{-7} =\boxed{1}[/tex]

The slope is 1.

24. Two planes intersect in a line. An example is attached.

Answer:

64.44

Step-by-step explanation:

Area of the rectangle:

A = bh

A = 7 x 11

A = 77

Area of a circle:

A = πr²

A = 3.14(2²)

A = 3.14(4)

A = 12.56

Combined:

77 - 12.56

64.44
