Answer:
P(AnB') = 1/7
P(A'UB') =5/7
P(B|A)=2/3
Step-by-step explanation:
from the venn diagram A and B shares 1,5
A = {1,4,5} this means sets found in A see the all values in first circle
B = {1,5,8,10,11} this means sets found in B see the all values in second circle
A'={8,10,11,12} this means sets NOT found in A see the all values NOT in first circle
B'={4,12} this means sets NOT found in B see the all values NOT in second circle
AnB={1,5} this means common sets shared by A and B
AuB = {1,4,5,8,10,11} this means sets in A or in B but do not write a number twice, example 1 is in A and B but you write it once.
AnB'={4} this means sets shared by A and B'
A'UB'={4,8,10,11,12} this means sets not in A' or not in B'
n=7 (count all the numbers you see)
I have written all the sets so we now solve for probabilities
P(A) = (numbers in A/All numbers (n) =3/7
P(B) = 5/7
P(AnB) = 2/7
P(AnB') = 1/7
P(A'UB') =5/7
P(B|A)=P(AnB) / P(A) = (2/7) ÷ (3/7) = (2/7)*(7/3) Reciprocal to change divide symbol to times symbol. Seven cancels out and you get 2/3.

Answers
Answer:
y = 3x-7
Step-by-step explanation:
Lines that are parallel have the same slopes.
y = 3x-4 ---> y=mx+b (slope = m=3)
point-slope formula for a line: y - y1 = m(x-x1)
slope=m=3

y - 2 = 3(x-3)
y - 2 = 3x-9
y = 3x-7
Given that ABCD is a rhombus, what is the value of x?
Answers
Answer:
B
Step-by-step explanation:
A rhombus is divided into four congruent triangles. The two given angles are complementary, meaning they add up to 90 degrees. Set up an equation:
[tex](4x-25)+x=90[/tex]
[tex]4x-25+x=90[/tex] Take out the parentheses
[tex]5x-25=90[/tex] Combine like terms
[tex]5x=115[/tex] Add 25 to both sides so as to isolate the variable
[tex]x=23[/tex] Divide both sides by 5

Answers
Answer:
D. [tex]x=-1, y=2\frac{2}{3}[/tex]
Step-by-step explanation:
Solving for x:
2x+3y=6
Subtract 3y from both sides
2x= -3y+6
Subtract 6 from both sides
2x-6= -3y
-4x+3y=12
Subtract 3y from both sides
-4x= -3y+12
Subtract 12 from both sides
-4x-12= -3y
Combine equations:
-4x-12=2x-6
Add 4x to both sides
-12=6x-6
Add 6 to both sides
-6=6x
6x= -6
Divide both sides by 6
x= -1
Solving for y:
2x+3y=6
Subtract 3y from both sides
2x= -3y+6
-3y+6=2x
Multiply both sides by -1
3y-6= -2x
Multiply both sides by 2
6y-12= -4x
-4x+3y=12
Subtract 3y from both sides
-4x= -3y+12
-3y+12= -4x
Combine equations:
6y-12= -3y+12
Add 3y to both sides
9y-12=12
Add 12 to both sides
9y=24
Divide both sides by 9

Partial fraction decomposition of 6x/(x-4)(x+2) is 4/(x-4) + 2/(x+2)
What is partial fraction decomposition?In algebra, the partial fraction decomposition or partial fraction expansion of a rational fraction is an operation that consists of expressing the fraction as a sum of a polynomial and one or several fractions with a simpler denominator.
Given, expression
6x/(x-4)(x+2)
Creating fraction template using denominator (x-4)(x+2) :
6x/(x-4)(x+2) = A/(x-4) + B/(x+2) ------(1)
Multiplying with (x-4)(x+2) on both sides
6x(x-4)(x+2)/(x-4)(x+2) = A(x-4)(x+2)/(x-4) + B(x-4)(x+2)/(x+2)
6x = A(x+2) + B(x-4)
Roots of the denominator are x = 4, -2
Putting x = 4,
6(4) = A (4+2) + B (4 - 4)
24 = 6A
A = 4
Putting x = -2
6(-2) = A (-2+2) + B (-2 - 4)
-12 = -6B
B = 2
Substituting value of A and B in equation 1
6x/(x-4)(x+2) = 4/(x-4) + 2/(x+2)
Hence,
4/(x-4) + 2/(x+2)
is the partial fraction decomposition of 6x/(x-4)(x+2).

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is $65. For
one performance, 40 advance tickets and 20 same-day tickets were sold. The total amount paid for the tickets was $1900. What was the price of each kind of
ticket?
Answers
Answer:
advance tickets $30.00
same day tickets $35.00
Step-by-step explanation:
1. In this equation, you are trying to find two values so you must use system of equations. Your two equations would be:
40x +20y = 1900
x + y = 65
x represents the price of advance tickets and y represents the price of same day tickets.
2. Solve the equation by performing elimination using multiplication. Multiple one equation by a constant to get two equations that contain opposite terms.
40x + 20y = 1900
-40(x + y = 65) → -40x + -40y = -2600
3. Add the equations, eliminating one variable. (add -40x + -40y = -2600 to 40x + 20y = 1900)
40x + 20y = 1900
+ -40x + -40y = -2600
Results in: -20y = -700
Solve for y by dviding both sides by -20.
y = 35
4. Substitute the solved value into one of the equations and solve for the remaining variable.
x + 35 = 65
Subtract 35 from both sides to solve for x.
x = 30
The advance tickets were $30.00 and the same day tickets were $35.00.
2x − 5y = 16
3x + 2y = 5
can you also explain how you did it. Thanks :)
Answers
Answer:
x=3
y=-2
Step-by-step explanation:
2x - 5y = 16
3x + 2y = 5
Solve for x in the first equation.
2x - 5y = 16
2x = 16 + 5y
x = (16 + 5y)/2
x = 8 + 5/2y
Put x as 8 + 5/2y in the second equation and solve for y.
3(8+5/2y) + 2y = 5
24+15/2y + 2y = 5
24 + 19/2y = 5
19/2y = 5-24
19/2y = -19
y = -2
Put y as -2 in the first equation and solve for x.
2x - 5(-2) = 16
2x +10 = 16
2x = 16-10
2x = 6
x = 3
