Find the probability of each event.
A politician is about to give a campaign speech and is holding a stack of thirteen cue cards, of which the first 3 are the most important. Just before the speech, she drops all of the cards and picks them up in a random order. What is the probability that cards #1, #2, and #3 are still in order on the top of the stack?
Answer:
The probability that cards # 1, # 2, and # 3 are still in order on the top of the stack is 0.045%.
Step-by-step explanation:
Since a politician is about to give a campaign speech and is holding a stack of thirteen cue cards, of which the first 3 are the most important, and just before the speech, she drops all of the cards and picks them up in a random order, to determine what is the probability that cards # 1, # 2, and # 3 are still in order on the top of the stack, the following calculation must be performed:
1/13 x 1/13 x 1/13 = X
0.076 x 0.076 x 0.076 = X
0.00045 = X
0.00045 x 100 = 0.045
Therefore, the probability that cards # 1, # 2, and # 3 are still in order on the top of the stack is 0.045%.

g(-12)=-9+2
g(-12)=-7
Help find the value of x pls
Answer:
x=61°
Step-by-step explanation:
We can see that angle 2x-6 has a corresponding angle above it, which is congruent. That angle is supplementary with angle x+3, meaning that their sum is 180°. We can tell because they form a straight line/straight angle.
So,
(2x-6)+(x+3)=180
2x-6+x+3=180
3x-3=180
3x=183
x=61
Question #5: You decided to paint one of the walls in the dining room the color blue. The shape of the wall is shown below. One gallon of paint covers 50 square feet. The wall will need two coats of paint. How many gallons of paint will you need to buy?

Gallons of paint needed:
Answer:
Step-by-step explanation:
Draw a horizontal line from the top corner of the left wall to the right wall. Now you have a rectangle on the bottom 8’x10’ (80 square feet) and a triangle on the top with a height of 5’ and a base of 8’. 1/2 base times height =20. You need to paint 100 sq feet so you need 2 gallons.

#26 What are the solutions to the equation 4x2 - 52x + 169 = 121?
A. {1, -12}
B. {-1, 12}
C. {-1, -12}
D. {1, 12}
Answer:
D. {1, 12}
Step-by-step explanation:
4X^2-52x+169=121
The equation can be summarized thus:
4X^2-52x+169-121=0
4X^2-52x+48=0
divide the each number of the equation by 4
4X^2/4-52x/4+48/4=0
x^2-13x+12=0
we need to numbers that when we multiply them the result is 12 and -13 when we add together
-1 and -12(-1-12=-13 and -1*-12=12)
x^2-x-12x+12
x(x-1)-12(x-1)
(x-1)(x-12)
x-1=0 or x-12=0
x=1 or x=12

one solution of x^2 - 64 = 0 is 8. what is the other solution
Given:
The equation is:
[tex]x^2-64=0[/tex]
One solutions is 8.
To find:
The other solution of the given equation.
Solution:
We have,
[tex]x^2-64=0[/tex]
It can be written as:
[tex]x^2-8^2=0[/tex]
[tex](x-8)(x+8)=0[/tex] [tex][\because a^2-b^2=(a-b)(a+b)][/tex]
Using zero product property, we get
[tex]x-8=0[/tex] and [tex]x+8=0[/tex]
[tex]x=8[/tex] and [tex]x=-8[/tex]
It is given that the one solutions is 8.
Therefore, the other solution is -8.
