Answer:

The answer is C

Step-by-step explanation:

the left graph end in x<2 and the right one in x≥2

OA, OB, and OC are all radii of the circle so they have the same length, 12 in. ∆ AOB is therefore isosceles, so the angles at the vertices A and B are congruent. The interior angles of any triangle sum to 180° in measure, so

30° + 2 m∠A = 180°   ⇒   m∠A = 75°

Draw an altitude in ∆ AOB that connects the vertex O to the midpoint of AB; this is the height h of ∆ AOB and bisects ∆ AOB into two 15°-75°-90° right triangles. Solve for h and the length of the base AB using trigonometry:

sin(15°) = (AB/2) / (12 in)   ⇒   AB = (24 in) sin(15°) ≈ 6.212 in

sin(75°) = h / (12 in)   ⇒   h = (12 in) sin(75°) ≈ 11.591 in

Then the area of ∆ AOB is

1/2 (AB) h = (144 in²) sin(15°) sin(75°)

= (72 in²) (cos(60°) - cos(90°))

= 36 in²

where we use the identity

sin(x) sin(y) = 1/2 (cos(x - y) - cos(x + y))

Let m∠BOC = θ. Then

(area of sector BOC) / θ = (area of ⊙O) / 360°

Solve for θ :

θ = (area of sector BOC) / (area of ⊙O) • 360°

θ = (36 in²) / (π (12 in)²) • 360°

θ = (90/π)° ≈ 28.648°

Answer:

5/7

Step-by-step explanation:

Since we have 7 cows in total our denominator would be 7 for now. 5 of the cows are red, so 5/7. Since we can't simplify 5/7 that is our final answer.

Answer:

y = 3x - 3

Step-by-step explanation:

Given, (2,3) and (-1,9), m = 3

Equation of a straight line is y = mx + c

Here, y = 3, x = 2 and m = 3

Substituting the values in y = mx + c we get,

3 = 3(2) + c

c + 6 = 3

c = 3 - 6

c = -3

So, the equation of the line is y = 3x - 3  (Answer).

Answer:

See below

Step-by-step explanation:

Arrange the list in ascending order

16 800   18400    19 950    23 400    26 500    47 800

MEDIAN is the middle number ...since there are TWO in the middle it is the average of the two    (19950 + 23400) /2 = 21675

MEAN is the average...add all of the numbers and divide by 6

   = 25475

Answer:          IQR = 16

Step-by-step explanation:

The given data is 25 th percentile is 64, 50th percentile is 74 and 75 th percentile is 80.

percentage : 25    50   75

 score        : 64    74    80

Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.

If the number of observations is odd, then the median is  observation

term

If the number of observations is even, then the median is  observation and  observations.

given n=3, middle term is '74'

In this given data the median is (M) = 74

Interquartile range IQR = median of upper half-median of lower half

                                      = 80-64

                                      = 16

                           IQR = 16

Answer:

Not sure

Step-by-step explanation:

Well I’m just guessing these numbers but…

For the coin it is one minus the probability of the coin landing on tails minus the tiny probability of the coin landing on its edge and balancing there. So something like (1 - 0.499 999 5 - 0.000 001), or 0.499 995; call it as near 0.5 as makes no difference.

For the number cube it is one minus the probability of the cube landing on one, three or five minus the tiny probability of the coin landing on an edge or the even tinier probability of it landing on a corner and balancing there. So something like (1 - 3 * 0.166 666 - 12 * 0.000 000 36 - 8 * 0.000 000 08) , or 0.499 998; call it as near 0.5 as makes no difference.

So the joint probability is the first probability times the second. So 0.5 * 0.5 which is 0.25 for all intents and purposes

Hi nice girl follow me I love you

The amount that marcus end up paying for the two shirts originally priced  at $28.99 and $30.29 is given by: Option A: $39.59

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, we're given that:

Cost of two shirts originally is $28.99 and $30.29

30% is off on each of them, so we get:

New price of each shirt = Old price of each shirt - 30% of old price of each shirt

New price of each shirt = [tex]28.99 - \dfrac{28.99}{100} \times 30[/tex] and [tex]30.29- \dfrac{30.29}{100} \times 30[/tex]

This sums up to $41.496

Now, at this price, there'd be application of 10% additional discount.

That will make the new price as:

[tex]41.496 - \dfrac{41.496}{100} \times 10 =37.3464[/tex]

Now, on this price, there'd be applied 6% sales tax

So, the amount he paid for 2 shirts = discounted price + 6% tax on discounted amount

= [tex]37.3464 + \dfrac{37.3464}{100} \times 6 \approx 39.59 \: \rm dollars[/tex]

Thus, the amount that marcus end up paying for the two shirts originally priced  at $28.99 and $30.29 is given by: Option A: $39.59

Answer:

(x+11)^2 + (y+8)^2 = 4^2/16

(x+6)^2 + (y+15)^2 = 5

Step-by-step explanation:

the standard equation of a circle is

(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

in the first equation -11 is h and -8 is k

so (x+11)^2 because when you subtract a negative the double negative creates a positive and that’s the same for (y+8)^2

so (x+11)^2 + (y+8)^2 = 4^2 or 16

in the second equations -6 is h and -15 is k

and the double negative is also effective in this equation so (x+6)^2 and (y+15)^2 therefore, (x+6)^2 + (y+15)^2 = 5 (the square root of 5 squared is just 5)

Answer

-7

Step-by-step explanation:

x + 21 = -2 x

-x          -x

21 = -3 x

---    -----

-3      -3

-7 = x

decimal from 6.0250 to 60250. is moving it four decimal places, so that is the same as multiplying by 1 followed by four zeros). This means that an equivalent fraction is 60250 / 10000.

B is true; pi= ~3.14. 3+4 is equal to 7, so because pi is greater than 3, pi+4>7
