The favourite colours represent the following angles: red (90°), blue (90°), green (135°) and yellow (45°).
Rule of Three
It's a math tool for solving problems about proportion. You can relate more than 2 variables and from the proportion, it's possible to find an unknown number.
Here you can apply the rule of three for finding the angle of each frequency. The total of people (400) represents the total angle of a circumference which is 360°.
For colour - red400 ----------- 360°
100 ------------ r
400r=360*100
400r=36000
r=36000/400
r=90°
For colour - blue400 ----------- 360°
100 ------------ b
400b=360*100
400b=36000
b=36000/400
b=90°
For colour - green400 ----------- 360°
150------------ g
400g=360*150
400g=54000
g=54000/400
g=135°
For colour - yellow400 ----------- 360°
50------------ y
400y=360*50
400y=54000
y=18000/400
y=45°

Hana is playing a virtual reality game in which she must toss a disc to land on the largest triangular section of the board. If the disc is equally likely to land anywhere on the board, what is the probability that she will succeed? Explain
Answers
Answer:
Her probability of success is 1/2
Step-by-step explanation:
Firstly, we have to calculate the area of the entire board
That would be the rectangle of the measure 50 cm by 40 cm
We have the area as the product of this two
That would be 50 * 40 = 2,000 cm^2
Now, the value calculated is the area of the entire possible landing area
Secondly, we need to get the area that counts as a success
that would be the area of the triangle that has a base of 50 cm and a height of 40 cm
The area of this is the product of the two divided by 2
we have this as ;
50 * 40 * 1/2 = 1,000 cm^2
So, her probability of success is simply the area of the triangle divided by the area of the rectangle
= 1000/2000 = 1/2

Is the ordered pair (-2, 1) a solution to the equation - 3x + y = 5?
No
Yes
Answers
Answer:
No
Step-by-step explanation:
Plug (-2,1) into -3x+y=5. This will make it -3(-2)+(1)=5. This is equal to 6+1=5. 7=5. 7 is not equal to 5. Therefore, (-2,1) is not a solution to the equation -3x+y=5.

A computer randomly selects a number from the given set. {2, 4, 6, 9, 16, 44, 51, 60, 78} What is the probability that a number less than 10 is selected? Enter your answer as a fraction, in simplest form, in the box. P(< 10) = Question 3 options: 59 49 29 89
Answers
Answer:
4/9
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 ids attached to the event. If it doesn't a value of zero is attached to the event.
Probability the number is less than 10 = total numbers less than 10 / sum of numbers

An air traffic controller at an airport sights a plane at an angle of elevation of 28º.

To the nearest foot, what is the distance from the control tower to the plane?
3190 ft
8463 ft
2113 ft
9585 ft
Answers
Answer:
8463 feets
Step-by-step explanation:
Using the diagram attached :
Distance of control tower to plane = d
Using tro:
Tan θ = opposite / Adjacent
Tan 28 = 4500 / d
0.5317094 = 4500 / d
0.5317094d = 4500
d = 4500 / 0.5317094
d = 8463.2690

How do you do rise over run
Answers
Answer:
Rise over Run is another term for the slope
Step-by-step explanation:
to find the slope, (y2 - y1)/(x2 - x1)
Answer:
If you look at a graph, you see 2 lines forming a "plus" shape. The horizontal line is called the x-axis, and the verticle line is called the y-axis. Rise over run is how much the y changes when the x changes. So if the graph increases its y value by 2 each time the x increases by 1, then rise over run is 2.

Choose the algebraic description that maps the image ΔXYZ onto ΔX′Y′Z′. Question options: A)
(x, y) → (x + 6, y – 1)
B)
(x, y) → (x – 5, y – 1)
C)
(x, y) → (x + 5, y – 1)
D)
(x, y) → (x – 6, y – 1)
Answers
Answer:
D
Step-by-step explanation:
To get from ΔXYZ (the figure on the right) to ΔX′Y′Z′ (the figure on the left), each point is translated left 6 units and down 1.
Movement left and right is related to the x-axis. So moving 6 units left (in a negative direction) is x - 6.
Movement up and down is related to the y-axis. So going down (in the negative direction) is y - 1.
What is the measure of the inscribed angle that shares endpoints with a central angle measuring 58 degrees?
Answers
Answer:
29 degrees
Step-by-step explanation:
See attached image of an inscribed angle together with a central angle.
An inscribed angle is half the measure of the central angle! Always! In my image, if the measure of angle CAB is 58 degrees, then that is also the measure of arc CB. The inscribed angle CDB is half the measure of the intercepted arc CB, so it's 29 degrees.

In a board game, students draw a number do not replace it, and then draw a second number. Determine the probability of each event occurring. Drawing an odd number then drawing a 6? dependent events. PLEASE HELP ME
Answers
The figure depicting the board game is attached below.
Answer:
Step-by-step explanation:
Kindly note that selections done without replacement.
Count of numbers on the board game = 8
Count of odd numbers = (1, 9, 1) = 3
Count of digit 6 = 3
Probability = required outcome / Total possible outcomes
P(picking an odd number) = 3 / 8
Without replacement
Numbers left on board game = 8 - 1 = 7
P(picking a 6) = 3 / 7
Hence,
P(picking an odd number then, a 6) = 3/8 * 3/7 = 9 / 56

There are 10 ice cream sandwiches, 5 drumsticks, and 6 vanilla ice cream cups in the freezer. You randomly select one and give it to your sister, then randomly select one for yourself. What is the probability of NOT selecting a drumstick and a vanilla ice cream cup? *
Answers
Answer:
The probability of not selecting a drumstick and a vanilla ice cream cup is 92.86%.
Step-by-step explanation:
Since there are 10 ice cream sandwiches, 5 drumsticks, and 6 vanilla ice cream cups in the freezer, and I randomly select one and give it to my sister, and then randomly select one for me, to determine what is the probability of not Selecting a drumstick and a vanilla ice cream cup, the following calculation should be performed:
5/21 x 6/20 = X
0.2380 x 0.3 = X
0.0714 = X
1- 0.0714 = X
0.9286 = X
0.9286 x 100 = 92.86
Therefore, the probability of not selecting a drumstick and a vanilla ice cream cup is 92.86%.
