Simple probability maze
To solve a simple probability maze calculate the probability in each situation and move through the maze based on these answers.
What is simple probability?This refers to the chances an event happens out of the total outcomes or number of favorable events/ total events.
How to solve a simple probability maze?In this type of maze, you are requested to find the probability of different events and based on this, you can follow a specific pattern to get out of the maze. Due to this, to solve the maze:
Calculate the probability of the first event. For example, the changes of rolling a 6 on the dice. 1 /6 (the dice has 6 sides) = one sixth or 0.166.Now that you have the correct answer move through the direction of that answer, which will take you to another situation.Keep calculating the probabilites and moving based on the answers.Learn more about probability in: https://brainly.com/question/11234923

What is the solution to the system of equations below? y = negative four-fifths x 6 and y = –30 (45, –30) (–30, 30) (–30, 45) (30, –30)
The solution to the system of equations is (45, –30)
How to determine the solution to the system of equations?The equations are given as:
y =-4/5x + 6
y = –30
Substitute y = –30 in y =-4/5x + 6
-30 =-4/5x + 6
Subtract 6 from both sides
-36 = -4/5x
Divide both sides by -4
9 = 1/5x
Multiply both sides by 5
x = 45
So, we have:
(x,y) = (45, –30)
Hence, the solution to the system of equations is (45, –30)

O True
O False
Question 1 True or False: A sector of a circle with a measure of 72 and radius of 12 cm has an arc length of about 15cm. True O False
Step-by-step explanation:
its false
The given statement about the sector of the circle is true.
What is a circle?A circle is a shape or a curve in a plane that has a fixed distance, called the radius, from a given point, called the centre. A circle is also the set of all points that are equidistant from the centre.
Given that we need to check whether a sector of a circle with a measure of 72° and radius of 12 cm has an arc length of about 15cm, or not,
Arc length = central angle / 360° × 2π × radius
= 72/ 360° × 2(3.14) × 12
= 0.2 × 6.28 × 12
= 15.072
≈ 15
Therefore, yes the sector of a circle with a measure of 72° and radius of 12 cm has an arc length of about 15cm.
Hence, the given statement about the sector of the circle is true.

Step-by-step explanation:
Given the points K(-2;5), L(1,3) and M(-5; 2p). Calculate the value
of p if KL ILM.
How do I solve this question?
The product of the perpendicular lines is a negative one. Then the value of p will be negative 3.75.
What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
Given the points K(-2,5), L(1,3) and M(-5, 2p).
If KL is perpendicular to LM. Then we have
The slope of KL will be
KL = (1+2)/(3-5)
KL = -1.5
The slope of LM will be
LM = (1+6)/(3-2p)
LM = 7/(3-2p)
We know the product of the perpendicular lines is a negative one.
KL x ML = -1
-1.5 x 7/(3-2p) = -1
-10.5 = -3 + 2p
2p = -7.5
p = -3.75

Viktoria knows that it is impossible to remove a red marble from her bag that has no red marbles in it. if she reaches into the bag and pulls out a marble without looking, what is the probability that the marble will be red? 0 startfraction 1 over 11 endfraction three-fourths 1
Because there are no red marbles on the bag, we will see that the probability is zero.
How to find the probability?We want to find the probability that the marble will be red. Viktoria knows that her bag has no red marbles, then it is impossible to get a red marble.
The probability of an impossible event is 0 (suppose that there are 10 marbles in the bag, we have a probability of 0 out of 10 of getting a red marble).
Then we can write the probability as P = 0.

use Demoiure's Theorem to find (-2-2√3i)³
Let z = -2 - 2√3 i.
Find the modulus of z :
|z| = √((-2)² + (-2√3)²) = √16 = 4
Find the argument of z (note that z lies in the third quadrant):
arg(z) = arctan(2√3/2) - π = arctan(√3) - π = -2π/3
Then in polar form, we have
[tex]z = -2 - 2\sqrt 3\, i = 4 \exp\left(-i\dfrac{2\pi}3\right)[/tex]
By DeMoivre's theorem, the cube of z is
[tex]z^3 = \left(4 \exp\left(-i\dfrac{2\pi}3\right)\right)^3 = 4^3 \exp(-i 2\pi) = \boxed{64}[/tex]

Find the volume of this cone round your answer to the nearest whole number use 3.14 for pi diameter = 5 mm, height = 6 mm
Answer:
Answer = 39.25 or 39 if rounded to the nearest whole number
Step-by-step explanation:
The formula for finding the volume of a cone is h(pi)(r^2)/3. We know that the height is 6 and the diameter is 5. Since we know the diameter we know that the radius is 2.5 since it is one half of the diameter. Now that he know the radius and height we can plug the values into the equation to get V=39.25

A line passes through the point , (−3, -4) and has a slope of 3. Write an equation in slope-intercept form for this line.
How do I solve this?
Answer:
y=3x+5
Step-by-step explanation:
Take the point you are given and plug it into whatever you're using (paper or a sight) take the slope and find another whole number that contents with the slope's path. now time for the easy part. make the start of the equation; in this case, its y=3x now once you have done that make a line that goes through the y axis, this will give you the y-intercept of 5. if you are using a sight then its way easier; you can either look and estimate where it crosses the y axis or you can start at a number and go up or down depending on how close you are to your 2 points. once you have done that you should have all you'll need to make the equation!
