Find the following trigonometric values.
Express your answers exactly.

Answer:

2/5

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Experimental probability is based on the result of an experiment that has been carried out multiples times

probability that the next contestant will win a prize = number of contestants that won in the last games / total number of contestants in the last games

To transform to the simplest form. divide both the numerator and the denominator by 4

Answer:

10x^2 + 10x + 1  - 3/(5x - 4),

Step-by-step explanation:

Long Division:

             10x^2  + 10x  + 1   <-------------------------   Quotient

5x - 4 )  50x^3 + 10x^2  - 35x  -  7

             50x^3 - 40x^2

                           50x^2 - 35x

                           50x^2  -40x

                                          5x  -  7

                                           5x -  4

                                                  -3 <-------------------Remainder

Part 1

Ying is correct while Jabbar is incorrect. The polar form would have cosine listed first, then sine later. The sine term always has the imaginary 'i' attached to it. It's fairly easy to mix these trig functions up. One way to remember is to think alphabetical order (C is before S, cosine before sine). Other than this difference, the two students have identical steps.

==========================================================

Part 2

Ying made the error this time. Jabbar is correct. When using a unit circle, you should find that

cos(pi/2) = 0

sin(pi/2) = 1

The point (x,y) on the unit circle that corresponds to the angle theta will help us see this. Note how x = cos(theta) and y = sin(theta).

Side note: Jabbar now has the correct order of cosine and sine (see part 1 above).

==========================================================

Part 3

Ying made the error of adding the r values. Instead, you should multiply them like Jabbar did. The theta angle values are the terms we add up. An interesting thing to notice is that Ying computed cos(pi/2) = 0, which contrasts to the mistake made in part 2.

==========================================================

Part 4

Ying is correct. You divide the r values, and the order of division is important. The order of division is from left to right. We have 7 on the left and -2 on the right, so that's why Ying ended up with the correct new r value of -7/2. Jabbar swapped the order incorrectly. The same issue shows up when subtracting the theta values. Keep in mind that the order of subtraction is important. Something like 2-3 = -1 is not the same as 3-2 = 1. Ying has the correct order of subtraction for those theta values.

Step-by-step explanation:

yes because it would give you numbers that you could then use to make some sort of chart to better understand your data

Part A: She needs to collect different types of data to form her classmates. It will help her to find which student spends the most time playing video games.

Part B: Yes, it is a statistical question.

What Zoe needs to do?

Zoe needs two main data from each of her classmates.

1. Name of her classmates.

2. Which student spends how much time playing video games.

After that, she can make a graph or a chart in order to understand which student spends more time playing video games.

Answer:

maybe B

Step-by-step explanation:

cuz interquaInterquartile is just a range of q1-q3

Answer:

A.Linear

B.exponential

C.exponential

D.quadratic

Answer:

A=Quadratic B=Exponential C=Quadratic D=Quadratic  

Step-by-step explanation:

Quadratic equations follow the formula ax^2+b+c and sometimes c or the third digit in the equation may not be there so C=0.

Exponential equations have exponents that are added to another exponent and supported by the base/coefficient.

Linear Equations have a specific formula which is Ax+By=C such a 2x+4y=8 and solve for both x and y.

There were no linear equations because none were solving for x and y, but most were quadratic equations and one exponential equation.

Answer:

[tex]V=4500\pi\ in^3[/tex]

Step-by-step explanation:

Given that,

The radius of a ball, r = 15 inches

We need to find the volume of a ball. The ball is in the shape of a sphere. The formula for the volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Put all the values,

[tex]V=\dfrac{4}{3}\pi \times (15)^3\\\\V=4500\pi\ in^3[/tex]

So, the volume of the ball is equal to [tex]4500\pi\ in^3[/tex].

Answer:

[tex]Area= 8[/tex]

Step-by-step explanation:

Given

[tex]I = (-9,-8)[/tex]

[tex]J = (-5,-6)[/tex]

[tex]K = (-7,-3)[/tex]

The complete part of the question is to calculate the area of IJK

The area is calculated using:

[tex]Area = \frac{1}{2}|x_1y_2 - x_2y_1 + x_2y_3 - x_3y_2 + x_3y_1 - x_1y_3 |[/tex]

Where:

[tex]I = (-9,-8)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]J = (-5,-6)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]K = (-7,-3)[/tex] --- [tex](x_3,y_3)[/tex]

So, we have:

[tex]Area = \frac{1}{2}|(-9*-6) - (-5*-8) + (-5*-3) - (-7*-6) + (-7*-8) - (-9*-3) |[/tex]

Solve the brackets

[tex]Area = \frac{1}{2}|54 - 40 + 15- 42 + 56 - 27 |[/tex]

[tex]Area = \frac{1}{2}|16|[/tex]

The absolute value of 16 is 16

So:

[tex]Area = \frac{1}{2} * 16[/tex]

[tex]Area= 8[/tex]

Answer:

15 < X > 31

Step-by-step explanation:

From triangle theorem,a triangle with sides X, Y, Z, the sum of any 2 sides must be greater than the third side i.e;

1. X + Y > Z

2. Y + Z > X

3. X + Z > Y

We are given 2 sides say Y = 8 and Z = 23.

Thus,Range of values is expressed as;

Z - Y < X > Z + Y

23 - 8 < X > 23 + 8

15 < X > 31

Answer:length of the east side=3.075km

Step-by-step explanation:

The west  side of Ms. Hammond's ranch=2.6 km long.

The  east side of Ms. Hammond's ranch = 475 m longer than the west side

Therefore East side =2.6 km +475 m

Changing 2.6 kmto m becomes  2.6 x1000=2600m

East side =2600m +475 m=3075m

3075m to km becomes 3075m/1000 =3.075km

Step-by-step explanation:

Answer:

66%

Step-by-step explanation:

0.6 repeating is 66%.

From decimal to percent:

To get a percent from a decimal number, move the decimal over twice to the right. In this case, 0.66 would become 66% because the decimal moved to the right twice.

From decimal to fraction to percent:

I already know that 2 divided by 3 is 0.6 repeating. 2 divided by 3 could also be written as [tex]\frac{2}{3}[/tex]. So the first step is complete, from the decimal 0.6 repeating to the fraction [tex]\frac{2}{3}[/tex]. Now from [tex]\frac{2}{3}[/tex] to a percent. If you get a 2 out of 3 ([tex]\frac{2}{3}[/tex]) you would get a 66%.
