Bailey rolls a pair of dice 12 times, and the sum of 6 came up 5 times to calculate the experimental and theoretical probabilities of rolling a sum of six with a pair of dice
Answers:
Experimental probability = 5/12
Theoretical probability = 5/36
========================================================
Explanation:
The experimental probability, aka empirical probability, is what we observe to happen. The event of rolling a six happens 5 times out of 12 total rolls. That leads directly to the experimental probability of 5/12
----------------------------
The theoretical probability is based on predetermined odds, and can be done on paper rather than actually rolling the dice.
There are 6*6 = 36 ways to roll two dice. Of those 36 ways, we have these cases that add to 6
1+5 = 62+4 = 63+3 = 64+2 = 65+1 = 6There are five ways to add to 6, out of 36 outcomes total.
This means the theoretical probability of getting a sum of 6 is 5/36

A triangular prism is 13 meters long and has a triangular face with a base of 12.6 meters and a height of 16.6 meters. What is the volume of the triangular prism?
Answer:
1359.54m^3
Step-by-step explanation:
The formula for the volume of a triangular prism is:
1/2([tex]b \times l )\times h[/tex]
b= base
l = length
h= height
Step 1: Plug the numbers into the formula
1/2(12.6*13)*16.6
Step 2: Simplify
163.8*16.6
1359.54
Step 3: Add units
The units used in the question were in meters, so the answer is also in meters.
Volume is always cubed, so it would be to the third power...1359.54m^3

The line equation in its slope-intercept form is y = 1.5 · (x - 8), the slope and the y-intercept of linear function are 1.5 (according to the information of the table) and -12, respectively.
How to determine a linear function in slope-intercept form
By analytical geometry we know that linear functions can be constructed by know the location of two distinct points on a Cartesian plane and the slope-intercept form is described below:
y - y₁ = m · (x - x₁) (1)
Where:
x - Independent variabley - Dependent variablex₁, y₁ - Coordinates of the know point.m - SlopeAccording the table, the slope of the function is 1.5, as there a change in y of 3 for a change in x of 2. Lastly, we determine the line equation in slope-intercept form: m = 1.5, x₁ = 8, y₁ = 0
y = 1.5 · (x - 8)
And the y-intercept is found for x = 0:
y = 1.5 · (0 - 8)
y = -12
The line equation in its slope-intercept form is y = 1.5 · (x - 8), the slope and the y-intercept of linear function are 1.5 (according to the information of the table) and -12, respectively. [tex]\blacksquare[/tex]

pls help me im really stuck
Answer:
10:1:5
Step-by-step explanation:
Let's mark names as their first letter:
Amy=A
Bill=B
Cara=C
The ratio should be like this A:B:C
A=10*B
C=A/2 or A*1/2
If it is the simplest, then Bill have to score 1 point.
10*1=10 (Amy's score)
10/2=5 (Cara's score)
If it is Amy:Bill:Cara then the ratio of points score by them is 10:1:5

Tickets for a play cost $3 for children and $10 for adults. A group of 25 people paid a total of $201 for tickets to the play. How many children were in a group?
Answer: There were 7 children
Step-by-step explanation:
Let's use x to represent the children and y to represent the adults.
We know they combine to make a group of 25 people so x+y=25
We also know that they paid $201 and that there is $3 per child and $10 for adults so 3x+10y=201
I will solve by substitution.
Solve for y in the first equation
[tex]x+y=25\\x-x+y=25-x\\y=25-x[/tex]
Sub in our value for y into the other equation and solve for x
[tex]3x+10y=201\\3x+10(25-x)=201[/tex]
Step 1) Simplify
[tex]3x+250-10x=201\\-7x+250=201[/tex]
Step 2) Subtract 250 from both sides
[tex]-7x+250-250=201-250\\-7x=-49[/tex]
Step 3) Divide both sides by -7
[tex]\frac{-7x}{-7} =\frac{-49}{-7}\\x=7[/tex]
Answer:
7 children.
Step-by-step explanation:
Let c = children
Let a = adults
1) We can set up two equations and solve them simultaneously using substitution or elimination method.
c + a = 25
3c + 10a = 201
2) I will use substitution. Make one of the variables the subject; then, substitute it into the other equation.
a = 25 - c
3c + 10(25 - c) = 201
3) Solve for c; then, substitute it into one of the equations.
3c + 250 - 10c = 201
-7c = 201 - 250
-7c = -49
c = -49/-7
c = 7
Let's substitute it into one of the equations.
7 + a = 25
a = 25 - 7
a = 18
Since the question only asked for the number of children, the answer is 7.

The centre C of the given circlee = (2, 2) P(5, 4) is a point on the circle. Join P to C and extend it to meet the circle at the other extremity Q of the diameter. Now PQ is a diameter of the circle with C as its midpoint. The the coordinates of Q be (x, y) The coordinates of midpoint are (2, 2) = [ (x +5)/2, (y + 4)/2] =%3E (x + 5)/2 = 2; =%3E x = 4 — 5 = —1 =%3E (y + 4) = 2; =%3E y = 4 — 4 = 0 The extremities of the diameter are (—1, 0) and (5, 4). Diameter² = [5 —(—1)]² + [ 4 —0]² = 6² + 4² = 36 + 16 = 52 Diameter = 2√13 We could have easily found the radius from the centre and the given point on the circumference.

Find the equation of the line parallel to y = - 1/2x -5, that passes through the point (4, -3). Write your answer in slope intercept form.
Answer:
y = -1/2x - 1
Step-by-step explanation:
Hi there!
We are given the equation y = -1/2x - 5
We want to write an equation parallel to this line, that passes through the point (4, -3)
Parallel lines have the same slope
In y=-1/2x-5, the equation is written in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
-1/2 is in the place of where m is, therefore it is the slope of the line
It is also the slope of the new line that we want to create.
As we already know the slope of this new line, we can substitute it into our equation (y=mx+b):
y=-1/2x+b
Now we need to solve for b
As the equation passes through the point (4, -3), we can use its values to help solve for b
Substitute 4 as x and -3 as y:
-3 = -1/2(4)+b
Multiply
-3 = -2+b
Add 2 to both sides
-1 = b
Now substitute -1 as b into the equation
y = -1/2x -1
Hope this helps!

to get the equation of any straight line, we simply need two points off of it, let's use those two points in the picture below.
[tex](\stackrel{x_1}{0}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{5}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{5}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{1}-\underset{x_1}{0}}}\implies \cfrac{3}{1}\implies 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_2=m(x-x_2) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_2}{5}=\stackrel{m}{3}(x-\stackrel{x_2}{1})[/tex]
keeping in mind that for the point-slope form, either point will do, in this case we used the second one, but the first one would have worked just the same.

Find the 2 consecutive integers whose squares have a difference of 239
Answer:
119 and 120
Step-by-step explanation:
let the consecutive integers be n and n + 1 , then
(n + 1)² - n² = 239
n² + 2n + 1 - n² = 239
2n + 1 = 239 ( subtract 1 from both sides )
2n = 238 ( divide both sides by 2 )
n = 119
n + 1 = 119 + 1 = 120
the 2 integers are 119 and 120
as a check
120² - 119² = 14400 - 14161 = 239
