The required sample size for the confidence interval and given margin of error is given as follows:

n = 1037.

A confidence interval of proportions has the bounds given by the rule presented as follows:

\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)

In which the variables used to calculated these bounds are listed as follows:

The margin of error is given as follows:

\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)

The confidence level is of 99%, hence the critical value z is the value of Z that has a p-value of \(\frac{1+0.99}{2} = 0.995\), so the critical value is z = 2.575.

As we have no estimate, the parameter is given as follows:

\(\pi = 0.5\)

Then the sample size for M = 0.04 is obtained as follows:

\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)

\(0.04 = 2.575\sqrt{\frac{0.5(0.5)}{n}}\)

\(0.04\sqrt{n} = 2.575 \times 0.5\)

\(\sqrt{n} = \frac{2.575 \times 0.5}{0.04}\)

\((\sqrt{n})^2 = \left(\frac{2.575 \times 0.5}{0.04}\right)^2\)

n = 1037.

Answer:

10   2/11

Step-by-step explanation:

Well, you just add -52/11+20/11 to get -32/11

then you have to take the -32/11 to the otherside to make it 80/11+32/11

so, y=10 and 2/11

The cost of a report is $0.934.

Given,

To produce 500 copies of a report required the following expenses costs:

- $25 supplies

- $550 total cost

- $48 equipment expenses

We need to find the cost per report.

We have,

Supplies cost + equipment cost + cost of 500 copies of report = $550

$25 + $48 + cost of 500 copies of report = $550

cost of 500 copies of report = $550 - $35 - $48

cost of 500 copies of reports = $467

We have,

500 copies of report = $467

Dividing both sides by 500

1 copy of report = $467/500 = $0.934

Thus the cost of one report is $0.934.

Hey there! I'm happy to help!

Our first square is the one in Quadrant 1.

OPTION A

The line y=x is one that goes upwards diagonally and passes through the origin. This just cuts the square in half, so reflecting over it would do nothing.

OPTION B

Rotating something 360 degrees just keeps it in the same spot.

OPTION C

Reflecting across the y-axis would put the first square on above the second square, so this option is wrong.

OPTION D

Translating the square 6 units to the left would put it very far away.

OPTION E

Rotating the square 180 degrees will put it in the diagonal quadrant. If you rotate the square it will be right where the second square is, so this translation is E. a rotation of 180 degrees about the origin

Answer:

a) the angle of ascent is 8.2°

b) the horizontal distance traveled is 4375 m

Step-by-step explanation:

depth of ocean = 626 m

distance traveled in the ascent = 4420 m

This is an angle of elevation problem with

opposite side to the angle = 626 m

hypotenuse side = 4420 m

a) angle of ascent ∅ is gotten from

sin ∅ = opp/hyp = 626/4420

sin ∅ = 0.142

∅ = \(sin^{-1}\) 0.142

∅ = 8.2°  this is the angle of ascent of the submarine.

b) The horizontal distance traveled will be gotten from Pythagoras theorem

\(hyp^{2}\) = \(opp^{2}\) + \(adj^{2}\)

The horizontal distance traveled will be the adjacent side of the right angle triangle formed by these distances

\(4420^{2}\) = \(626^{2}\) + \(adj^{2}\)

adj = \(\sqrt{4420^{2}-626^{2} }\)

adj = 4375 m  this is the horizontal distance traveled.

The resulting image of Triangle ABC after reflecting it across the line y=-x and rotating it 90 degrees clockwise is Triangle A''B''C'' with vertices at (2, 3), (1, 4), and (5, 1).

To find the resulting image of Triangle ABC after reflecting it across the line y=-x and rotating it 90 degrees clockwise, we can follow these steps:
1. Draw Triangle ABC and the line y=-x on a coordinate plane.
2. Reflect Triangle ABC across the line y=-x to get its image, Triangle A'B'C'.
3. Draw the image Triangle A'B'C' on the coordinate plane.
4. Rotate Triangle A'B'C' 90 degrees clockwise around the origin to get its final image.
5. Draw the final image of Triangle ABC, which is Triangle A''B''C''.
To find the coordinates of the image points, we can use the transformation rules for reflections and rotations.
First, let's find the image points after reflecting Triangle ABC across the line y=-x:
- The point A(-2, 3) is reflected to the point A'(-3, 2) by swapping the x and y coordinates and changing their signs.
- The point B(4, 1) is reflected to the point B'(-1, -4) by swapping the x and y coordinates and changing their signs.
- The point C(1, 5) is reflected to the point C'(-5, -1) by swapping the x and y coordinates and changing their signs.
Now, let's find the image points after rotating Triangle A'B'C' 90 degrees clockwise around the origin:
- To rotate a point (x, y) 90 degrees clockwise around the origin, we can use the formulas (-y, x).
- Applying this formula to each image point, we get:
 - A''(2, 3)
 - B''(1, 4)
 - C''(5, 1)
Therefore, the resulting image of Triangle ABC after reflecting it across the line y=-x and rotating it 90 degrees clockwise is Triangle A''B''C'' with vertices at (2, 3), (1, 4), and (5, 1).

The amount that you need to save per month to fund the emergency fund would be $ 861. 58.

The discretionary money left per month would be $ 585. 88.

The gross income for the month :

= 17. 50 x 40 per week x 4 weeks a month

= $ 2, 800

The amount left which is realized funds for the month is:

= Gross income - FICA + Federal tax withholding + State tax withholding

= 2, 800 x ( 1 - 26. 15 %)

= $ 2, 067. 80

Five months of realized income for the emergency fund is:

= 2, 067. 80 x 5

= $ 10, 339

The amount to save per month is:

= 10, 339 / 12

Toby rode his bike further.  He rode 74 miles further than Wendy.  

Step-by-step explanation:

7 miles per day for 26 weeks is, 7 times 7 times 26, which is a total of  1274 miles.  200 miles each month for 6 months is 6 times 200, which equals 1,200 miles.  Toby rode more miles.

When the directrix of the parabola is the line y = -1 and the focus is (0, -2), the equation of the parabola is :

                                 y = -1/2x²  - 3/2

What is a parabola?

Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve. It's crucial to remember that the fixed point is not located on the fixed line.

A line that is perpendicular to the parabola's axis is known as the directrix of a parabola. The parabola's directrix is useful in defining it. The line that passes through the focus and is perpendicular to the directrix is the parabola's axis. The vertex of the parabola is the location where it crosses the axis.

Given,

The focus of the parabola = (0, -2) = (a,b)

The directrix of the parabola is y = -1 = c

The directrix is a horizontal line.

So the axis of the parabola is vertical.

Then the parabola is either an upward or downward parabola.

The focus lies below the directrix.

So the parabola is a downward parabola.

The vertex is equidistant from the focus and directrix.

So vertex = (0,-1.5) = (h,k)

h = 0

k = - 1.5

The equation of directrix is:

y = k+a = -1

-1.5 + a = -1

a = 0.5

Then the equation of the parabola is:

(x-h)² = -4a (y-k)

(x-0)² = -4* 0.5 (y+1.5)

x² = -2y - 3

x² + 3 = -2y

y = -1/2x²  - 3/2

Therefore when the directrix of the parabola is the line y = -1 and the focus is (0, -2), the equation of the parabola is :

                                 y = -1/2x²  - 3/2

Answer:

  76 units

Step-by-step explanation:

You want the length of AC in the given triangular pyramid.

The Pythagorean theorem can be used to find the lengths of AD and CD.

  AD² + 40² = 41²

  AD² = 41² -40² = 81 . . . . . = 9²

and

  CD² +40² = 85²

  CD² = 85² -40² = 5625 . . . . . = 75²

It can also be used to find AC:

  AD² + CD² = AC²

  81 + 5625 = AC²

  AC = √5706 = 3√634 ≈ 76

The length of side AC is about 76 units.
