Step-by-step explanation:

Answer:

Step-by-step explanation:

Directions

Givens

AC = 13 inches                   Given

CB = 24 inches                  Given

CE = 12 inches                    Construction and property of a midpoint.

So what we have now is a right triangle (ACE) with the right angle at E.

What we seek is AE

Formula

AC^2 = CE^2 + AE^2

13^2 = 12^2 + AE^2

169 = 144 + AE^2                     Subtract 144 from both sides.

169 - 144 = 144-144 + AE^2     Combine

25 = AE^2                                Take the square root of both sides

√25 = √AE^2

5 = AE

Answer

The 24 inch chord is 5 inches from the center of the circle.

The appropriate values are; [tex]sin \theta = \frac{3\sqrt{10} }{10 }[/tex], [tex]cos\theta = -\frac{\sqrt{10} }{10}[/tex], [tex]cot\theta= -\frac{1}{3}[/tex], [tex]sec\theta=-\sqrt{10}[/tex] and [tex]csc\theta= \frac{\sqrt{10} }{3}[/tex].

Given the equation and interval.

tanθ = -3, [ π/2 < θ < π ]

First, we use the definition of tangent to determine the known sides of the unit circle right triangle.

Note that; the quadrant determines the sign of each values.

tanθ = opposite / hypotenuse

We can use Pythagoras theorem to find the hypotenuse of the unit circle right triangle as the opposite and adjacent sides are known.

Hypotenuse = √( opposite² + adjacent² )

Hence, we have;

Hypotenuse = √( [3]² + [-1]² )

Hypotenuse = √( 9 + 1 )

Hypotenuse = √10

1) To find sinθ

sinθ = opposite / hypotenuse

sinθ = 3/√10

We simplify

sinθ = 3/√10 × √10/√10

sinθ = 3√10 / 10

[tex]sin \theta = \frac{3\sqrt{10} }{10 }[/tex]

2) cosθ

cosθ = adjacent / hypotenuse

cosθ = -1 / √10

Simplify

cosθ = -1 / √10 × √10/√10

cosθ = -√10 / 10

[tex]cos\theta = -\frac{\sqrt{10} }{10}[/tex]

3) cotθ

cotθ = adjacent / opposite

cotθ = -1 / 3

[tex]cot\theta= -\frac{1}{3}[/tex]

4) secθ

secθ = hypotenuse / adjacent

secθ = √10 / -1

[tex]sec\theta=-\sqrt{10}[/tex]

5) cscθ

cscθ = hypotenuse / opposite

cscθ = √10 / 3

[tex]csc\theta= \frac{\sqrt{10} }{3}[/tex]

Therefore, the appropriate values are; [tex]sin \theta = \frac{3\sqrt{10} }{10 }[/tex], [tex]cos\theta = -\frac{\sqrt{10} }{10}[/tex], [tex]cot\theta= -\frac{1}{3}[/tex], [tex]sec\theta=-\sqrt{10}[/tex] and [tex]csc\theta= \frac{\sqrt{10} }{3}[/tex].

Using proportions, it is found that:

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The unit price is given by the cost divided by the number of ounces, and the better deal is given by the deal with the lowest unit price.

Hence, for the 11.3 ounce package:

u = 3.68/11.3 = $0.33 per ounce.

For the 29.3 ounce package:

u = 8.98/29.3 = $0.31 per ounce.

In the context of probability, an experiment is a process:

First, he has to decide on a pair of shirts and he has 7 different colors to choices.

A value between 0 and 1, inclusive, describes the relative possibility (chance or likelihood) that an event will occur.

For each of those choices he has a choice of 7 different shirts, so that gives him 3 times 7 = 21 different shirts.

For each of those 21 possibilities, he has 21 times 3 = 63 different outfits, and some of them may be acceptable to wear in public.

Yes at 0.05 significance level we can conclude that mean income of those selecting plan B is bigger.

Given mean yearly income for sample of 40 subscribers is $57000 with standard deviation of $9200, mean yearly income for sample of 30 subscribers with standard deviation of $7100.

First we have been given significance level (α) of 0.05. So (1-α)=1-0.05=0.95 and we have to find Z score for this significance level. (1+0.95)/2=0.425

Z=1.44

Now we have to calculate margin of error which will be calculated as under:

[tex]M_{A} =Z*st/\sqrt{n}[/tex]

=[tex]1.44*9200/\sqrt{40}[/tex]

=1.44*9200/6.32

=1869.10

[tex]M_{B}=Z*st/\sqrt{n}[/tex]

=[tex]1.44*7100/\sqrt{30}[/tex]

=1.44*7100/3.47=2096.2

We know that margin of error shows the difference between real and calculated values. So if we increase mean of both plans by margin of error of respective plans then mean of plan A becomes=57000+1869.10=58869.10 and mean of plan B becomes =61000+2096.2=630622.2. We can clearly notice that mean of plan B is greater.

Hence it is reasonable to say that the mean of plan B is greater at the significance level of 0.05.

c^2 = 1^2 + 12^2  

c^2 = 1 + 144

The picture is attached below.

The value of n is 31.

The median is the line connecting the vertex and its midpoint on the opposite side of the triangle.

The intersection of all 3 medians of the triangle is called the centroid.

As we know centroid divides the median in the ratio of 2:1.

In the given picture,

Medians of triangle △ABC are AM, BL, and CK.

So the centroid of the triangle is O.

Given that KC= 108

As the centroid O divides the line KC in 2:1.

Let OC=2x

KO= X

As KC= KO+OC

⇒ 108= x+2x

⇒ 3x=108

⇒ x=108/3

⇒ x=36

Then OC= 2x= 2*36= 72

As given in the question OC= 2n+10

putting the value of OC in above equation

⇒ 72= 2n+10

⇒ 2n= 72-10

⇒ 2n=62
