Each event uses a standard deck of playing cards. The cards are chosen at random and put back after each draw.
Match each event with its theoretical probability.
You choose a red card.
You choose the queen of hearts.
You choose a club.
You choose a 5, 6, or 7. 11 :: 3 13 52
PUT THEM IN ORDER! AND I'LL GIVE YOU "⭐"
Answers
Answer:
See below
Step-by-step explanation:
The probability of choosing a red card is 1/2. Half of the cards are hearts/diamonds and half of the cards are clubs/spades.
The probability of choosing the queen of hearts is 1/52. There is one queen of hearts in a 52 card deck.
The probability of choosing a club is 1/4. 1/4 of the cards are clubs, 1/4 are spades, 1/4 are diamonds, 1/4 are hearts.
The probability of choosing a 5, 6, or 7 is 3/13. There is a 5, 6, 7 in all 4 sets, clubs, spades, hearts, and diamonds. So there are 12 total cards that either read 5, 6, or 7 out of the 52 total cards. 12/52 simplifies to 3/13.

The price of a video game was reduced from $60 to $45. By what percentage was the price of the Vedic games reduced.
Answers
Answer:
[tex]33.3\%[/tex]
Step-by-step explanation:
Given: price of a video game was reduced from [tex]\$60[/tex] to [tex]\$45[/tex]
To find: percentage decrease in the price of the Vedic games
Solution:
Old price of the game [tex]=\$60[/tex]
New price of the game [tex]=\$45[/tex]
Decrease in the price of the Vedic games [tex]=\$60-\$45=\$15[/tex]
Percentage decrease in the price of the Vedic games = (Decrease in the price of the Vedic games × 100) ÷ New price of the game
[tex]=\frac{15(100)}{45} =\frac{100}{3}\%=33.3\%[/tex]
find the vertex form of 4x^2+8x-8
Answers
Answer:
4(x + 1)^2 - 12.
Step-by-step explanation:
f(x) = 4x^2 + 8x - 8
f(x) = 4(x^2 + 2x) - 8
f(x) = 4[(x + 1)^2 - 1) - 8
f(x) = 4(x + 1)^2 - 4 - 8
f(x) = 4(x + 1)^2 - 12.

Solve the system (2 points)
Write the solution as a point (x, y) (2 points)
Answers
Answer:
x = -5 y = -5
Step-by-step explanation:
–x + 4y = -15
- 4y -4y
-1(-x = -4y - 15)
x = 4y + 15
Substitute x = 4y + 15 into 3x + 5y = -40
3(4y + 15) = -40
17y + 45 = -40
- 45 -45
17y = -85
/ 17 /17
y= -5
Substitute y = - 5 into x = 4y + 15:
x = 4(-5) + 15
x = -20 + 15
x = -5
Answer:
Part I
(-5,-5)
Part II
(3.75, 312.50)
Step-by-step explanation:
Part I
(1) 3x + 5y = -40
(2) -x + 4y = -15
solve for x in (2)
x = 15 + 4y
substitute into (1)
3(15+4y) + 5y = -40
45 +12y + 5y = -40
45 +17y = -40
17y = -85
y = -5
substitute y = -5 into (1)
3x + 5(-5) = -40
3x -25 = -40
3x = -15
x = -5
so (-5, -5)
Part II
Studio A

Studio B
C = 200 + 30t
125 + 50t = 200 + 30t

carpenter has a board that is 8 feet long. e cuts off two pieces. One piece is 32 feet ug and the other is 2 feet long. How ch of the board is left?
Answers
Answer:
2 1/6 feet
Step-by-step explanation:
A carpenter has a board that is 8 feet long. He cuts off two pieces. One piece is 3 1/2 feet long and the other is 2 1/3 feet long. How much of the board is left?
Total length of the board = 8 feet
Piece A = 3 1/2 feet
Piece B = 2 1/3 feet
Piece A + piece B
= 3 1/2 feet + 2 1/3 feet
= 7/2 + 7/3
= (21+14) / 6
= 35/6
= 5 5/6 feet
Length of the board remaining = Total length of the board - length of the two pieces
= 8 feet - 35/6 feet
= (48-35) / 6
= 13/6 feet
= 2 1/6 feet
Length of the board remaining = 2 1/6 feet
