Use a confidence level of 90% to complete parts (a) through (d) below.
a. Identify the critical value ta/2 used for finding the margin of error.
¹a/2=
(Round to two decimal places as needed.)

Answers

Answer 1

The critical value is given as 1.69

The margin of error is 0.00161

How to solve for the critical value

We are to find the critical value ta/2  used for finding the margin of error

T∝ / 2 = 1 - 0.10 / 2

1 - 0.05 = 0.95

The critical value at the level if we use the critical value table is 1.69

2. Next we would have to solve for the margin of error

When comparing your results to the actual population value, a margin of error indicates how many percentage points they will deviate.

ME= [tex]z * \frac{s}{\sqrt{n} }[/tex]

z is the critical value = 1.69

s = standard deviation = 0.00573

n = sample size

where z = 1.69

s = 0.00573

n = 36

We would have to put these values in the formula above to get the margin of error

[tex]1.69 * \frac{0.00573}{\sqrt{36} }[/tex]

Margin of error = 0.00161

Find The a9 to each sequence.

an=-2(-5)n-1

an=6(-3)n-1

an=-7 n-1

These are Geometeic Sequences and It's asking for the a9, which I believe is the 9th term for all of them step by step.​

Answers

Answer:

Fore an=-2(-5)n-1

:substitutute 9 in place of "n" in the equation

= -2(-5)9-1

Multiply -2 and -5 to get positive 10

=(10)(9)-1

Multiply 10 and 9 to get 90

=90-1

Subtract 1 from 90

=89 therefore 9th term is 89

Step-by-step explanation:

For

an= 6(-3)n-1

(Follow the above procedure)

=6(-3)9-1

=-18-1

Complete the equation of this circle :

Answers

Answer:

-2 , 4 , 36

Step-by-step explanation:

[tex](x - -2)^{2} + (y - 4)^{2}[/tex]

[tex](x + 2)^{2} + (y - 4)^{2} =36[/tex]

The equation of the circle with a radius of 6 and center (-3, 4) is (x + 3)² + (y - 4)² = 36.

The equation of a circle with radius r and center (h, k) is given by:

(x - h)² + (y - k)² = r²

Radius (r) = 6

Center (h, k) = (-3, 4)

Plugging these values into the equation, we have:

(x - (-3))² + (y - 4)² = 6²

(x + 3)² + (y - 4)² = 36

Therefore, the equation of the circle with a radius of 6 and center (-3, 4) is (x + 3)² + (y - 4)² = 36.

A 12 foot ladder leans against a building. The angle of elevation from the ground to the foot of the ladder is 46°. Find, to the nearest tenth of a foot, how far is the foot of the ladder from the building

Answers

Answer:

8.3 ft

Step-by-step explanation:

Hypotenuse is the longest side

Opposite is the side opposite the angle

Adjacent is the remaining side

Draw the triangle out, and you'll find that the hypotenuse (length of ladder) is 12ft, and that you are looking for the adjacent side (length of the foot of the ladder to the building). Rule out the opposite side (side of building) as it is not needed. The appropriate trigonometric formula is then the [tex]cos(angle) = \frac{adjacent}{hypotenuse}[/tex], rearranged to find the adjacent side is [tex]adjacent = cos(angle)*hypotenuse[/tex]  

substitute the values in and you get cos(46) x 12 = 8.335900446

Answers

Answer/Step-by-step explanation:

Given:

f(x) = -3x + 4

✔️First row, find x when f(x) = 4:

Substitute f(x) = 4 into the equation

4 = -3x + 4

4 - 4 = -3x

0 = -3x

Divide both sides by -3

0/-3 = x

x = 0

✔️ Second row, find f(x) when x = -1:

Substitute x = -1 into the equation

f(-1) = -3(-1) + 4

f(-1) = 3 + 4

f(-1) = 7

✔️ Third row, find f(x) when x = 1:

Substitute x = 1 into the equation

f(1) = -3(1) + 4

f(1) = -3 + 4

f(1) = 1

✔️ Fourth row, find x when f(x) = 9:

Substitute f(x) = 9 into the equation

9 = -3x + 4

9 - 4 = -3x

5 = -3x

Divide both sides by -3

5/-3 = x

x = -⁵/3

a/sin 120=8/sin 40

Which simplifies to: 8*sin (120)/sin (40)

When you put the equation into a calculator, it will answer with 10.77

Therefore, it will be 10.8 if round to the nearest tenth

Using the same concept of the answer to a, the equation will be:

10.8*sin 20/sin 120=4.26

Step-by-step explanation:

4. The radius is the distance between the center (-6, -8) and the point on the circle (0, 0). The square of that is given by ...

  r^2 = (-6-0)^2 +(-8-0)^2 = 36 +64 = 100

Only one of the offered choices has an r^2 value of 100: Choice B.

5. The center and the point are on the same line (y=9), so the radius is the difference of x-coordinates: r = 5-2 = 3. The center is given as (h, k) = (5, 9).

The form of the equation of a circle is ...

  (x -h)^2 +(y -k)^2 = r^2

Answers

Answer:

[tex]g'(x) = \frac{x^2}{100} +2[/tex]

Step-by-step explanation:

Given

[tex]g(x) = 10\sqrt{x - 2[/tex]

Required

Determine the inverse function

[tex]g(x) = 10\sqrt{x - 2[/tex]

Replace g(x) with y

[tex]y = 10\sqrt{x -2[/tex]

Swap the positions of x and y

[tex]x = 10\sqrt{y -2[/tex]

Divide through by 10

[tex]\frac{x}{10} = \sqrt{y - 2[/tex]

Square of both sides

[tex]\frac{x^2}{100} = y - 2[/tex]

Make y the subject

[tex]y = \frac{x^2}{100} +2[/tex]

Replace y with g'(x)

[tex]g'(x) = \frac{x^2}{100} +2[/tex]

Hence, the inverse function is: [tex]g'(x) = \frac{x^2}{100} +2[/tex]
