Step-by-step explanation:
may someone please help me understand something in class? its theoretical and experimental probability basically just probability in a whole and I can’t understand. I don’t need the definition I just want someone to make me understand in a simple way like a tutor, but anyways please help me understand this. Examples would work, anything. Just help me understand. Thanks anyways.
Experimental probability is the results of an experiment, let's say for the sake of an example marbles in a bag. Experimental probability would be drawing marbles out of the bag and recording the results. Theoretical probability is calculating the probability of it happening, not actually going out and experimenting.
hope this helped.
Give an example of an equation with an infinite number of solutions. Then make one change to the equation so that it has no solution.
An example of an equation with infinitely many solutions: 4x + 3 = 4x +_____
The equation with one change and no solutions: 4x + 3 = ______
Answer:
I)3 II)4x
Step-by-step explanation:
for the infinite number of solutions you need to make both equations on both sides equal
but in the one for no solution you need to make one number is equal to another number, which is wrong in Math, that's why there's no solution in it

Answer: Ok so I may be wrong but I got 84ft
Step-by-step explanation: The bottom looks like a rectangle so it would be 4 times 12. 4 times 12 equals 48. since the height is 4 it would be 10-4 which equals 6. 6 Times 12 divided by two equals 36. 36 plus 48 is 84.

Answer:
A = 12/5 units
Step-by-step explanation:
USING ALGEBRA:
We can find the intersection point between these two lines;
y = 3x - 6
y = -2x + 8
Set these two equations equal to each other.
3x - 6 = -2x + 8
Add 2x to both sides of the equation.
5x - 6 = 8
Add 6 to both sides of the equation.
5x = 14
Divide both sides of the equation by 5.
x = 14/5
Find the y-value where these points intersect by plugging this x-value back into either equation.
y = 3(14/5) - 6
Multiply and simplify.
y = 42/5 - 6
Multiply 6 by (5/5) to get common denominators.
y = 42/5 - 30/5
Subtract and simplify.
y = 12/5
These two lines intersect at the point 12/5. This is the height of the triangle formed by these two lines and the x-axis.
Now let's find the roots of these equations (where they touch the x-axis) so we can determine the base of the triangle.
Set both equations equal to 0.
(I) 0 = 3x - 6
Add 6 both sides of the equation.
6 = 3x
Divide both sides of the equation by 3.
x = 2
Set the second equation equal to 0.
(II) 0 = -2x + 8
Add 2x to both sides of the equation.
2x = 8
Divide both sides of the equation by 2.
x = 4
The base of the triangle is from (2,0) to (4,0), making it a length of 2 units.
The height of the triangle is 12/5 units.
Formula for the Area of a Triangle:
A = 1/2bh
Substitute 2 for b and 14/5 for h.
A = (1/2) · (2) · (12/5)
Multiply and simplify.
A = 12/5
The area of the region bounded by the lines y = 3x - 6 and y = -2x + 8 between the x-axis is 12/5 units.
The model below represents an equation. Write the equation that is modeled then find what value of x makes the equation true. HELP PLZ PLZ PLZ PLZ
What is the slope. Please answer, this is worth 20 points!
Answer:
2
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
The slope is equal to the rise/run of the line, or in other words, the number of units it travels up over the number of units it travels right. We can see on the graph that for every time it travels right 1 unit it travels up 2 units, so the rise/run is 2/1. 2/1 is equal to 2, so therefore, the slope of the line is 2.

What is the value of x?
11 (9 - 2x) = -(12x + 11)
Answer:
x=11
Step-by-step explanation:
First Distribute 11 to 9 and -2x
Then distribute the negative to 12x and 11
Then calculate like terms
-22x + 12x = -11 -99 which comes out to -10x=-110
Then divide each side by -10
Your answer will then be x=11

What is the perimeter of the figure on the coordinate plane below?
Answer:
26 units
Step-by-step explanation:
im not sure if this will help but i counted the spaces and added the halves
The perimeter of the given figure on the coordinate plane is 56 units.
What is perimeter?A perimeter is the closed path that encompasses surrounds, or outlines either a two dimensional shape or a one-dimensional length.
Now from given figure, the following length of the sides is given,
9 units
4 units
4 units
8 units
11 units
3 units
2 units
15 units
Now since we know that,
Perimeter = Sum of lengths of all the sides
⇒ Perimeter = 9+4+4+8+11+3+2+15
⇒ Perimeter = 56 units
Thus, the perimeter of the given figure on the coordinate plane is 56 units.
