Correct Question
A standard deck of 52 cards contains 4 suits: hearts, clubs, diamonds, and spades. Each suit consists of cards numbered 2 through 10, a jack, a queen, a king, and an ace.
Anthony decides to pick one card at random from a standard deck of 52 cards. Let A be the events that he chooses an ace and H be the event that he chooses a heart.
What is P ( A or H), the probability that the card Anthony chooses is either an ace or a heart?
Answer:
2/13
Step-by-step explanation:
From the question, we have in total, 52 cards.
Step 1
We find the probability that Anthony chooses an Ace.
Number of ace cards in each of four suits namely spades, hearts, diamonds and clubs = 1
Therefore, total number of ace cards out of 52 cards = 4
P(A) = 4/52
Step 2
We find the probability that Anthony chooses an Ace.
Probability that Anthony chooses an heart P(H) = 4/52
Step 3
The probability that the card Anthony chooses is either an ace or a heart
P ( A or H) = P(A) + P(H)
= 4/52 + 4/52
= 8/ 52 = 2 /13

5 + x = -2
I need work and answer!!!!
We need to get x by itself.
We do that by subtracting 5 from both sides.
This leaves us with x = -7.
So x = -7 is the solution.
Answer:
The final answer is [tex]x = -7[/tex] .
Step-by-step explanation:
Solve the equation:
[tex]5 + x = -2[/tex]
Subtract both sides by 5:
[tex]5 - 5 + x = -2 -5[/tex]
[tex]x = -7[/tex]
So, therefore, [tex]x = -7[/tex] is the final answer.
If 80% of an item is $144.00, what is the original price?
Answer:
180
Step-by-step explanation:
Answer:
180
Step-by-step explanation:
the original price * 80% = 144
Change to decimal form
the original price * .80 = 144
Divide each side by .80
the original price * .80/.80 = 144/.80
the original price =180

3x+6i=27+yi
x
Answer:
x = 9
y = 6
Step-by-step explanation:
3x+6i=27+yi
The real components have to be equal and the imaginary components have to be equal
3x = 27
divide by 3
3x/3 = 27/3
x=9
6i = yi
Divide by i
6 = y
Answer:
x=9, y=6
Step-by-step explanation:
Step-by-step explanation:
we have
3x+6i=27+yi
Equate the Real Numbers
3x=27
solve for x
Divide by 3 both sides
x=27/3=9
Equate the Imaginary Numbers
6i=yi
Simplify
6=y
Rewrite
y=6
therefore
x=9, y=6

Y=7
Step-by-step explanation:
Move all terms not containing y to the right side of the equation.
4y=22+6
Then add 22 and 6.
4y=28
Divide each term in 4y=28 by 4
4y÷4=28÷4
Cancel the common factor of 4 in the first part of the equation so it looks like this...
y=28÷4
Divide 28 by 4.
Therefore y=7

What is the x-value in the solution to the system of linear equations?
y = 1/2x + 2
y = -3/2x -2
Answer: The value of x is -2.
Step-by-step explanation:
y= 1/2x + 2
y= -3/2x-2
1/2x + 2 = -3/2x -2
+2 +2
1/2x + 4 = -3/2x
-1/2x -1/2x
4= -2x
x= -2

GIVING BRAINLIST TO THE CORRECT ANSWER PLS ANSWER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
a = -1/2 & k = 3/7
Step-by-step explanation:
Solve for a over the real numbers:
24 a^3 + 8 a^2 + 6 a + 4 = 0
The left hand side factors into a product with three terms:
2 (2 a + 1) (6 a^2 - a + 2) = 0
Divide both sides by 2:
(2 a + 1) (6 a^2 - a + 2) = 0
Split into two equations:
2 a + 1 = 0 or 6 a^2 - a + 2 = 0
Subtract 1 from both sides:
2 a = -1 or 6 a^2 - a + 2 = 0
Divide both sides by 2:
a = -1/2 or 6 a^2 - a + 2 = 0
Divide both sides by 6:
a = -1/2 or a^2 - a/6 + 1/3 = 0
Subtract 1/3 from both sides:
a = -1/2 or a^2 - a/6 = -1/3
Add 1/144 to both sides:
a = -1/2 or a^2 - a/6 + 1/144 = -47/144
Write the left hand side as a square:
a = -1/2 or (a - 1/12)^2 = -47/144
(a - 1/12)^2 = -47/144 has no solution since for all a on the real line, (a - 1/12)^2 >=0 and -47/144<0:
Answer: a = -1/2
______________________________________
Solve for k over the real numbers:
(7 k - 3) (k^2 - 2 k + 7) = 0
Split into two equations:
7 k - 3 = 0 or k^2 - 2 k + 7 = 0
Add 3 to both sides:
7 k = 3 or k^2 - 2 k + 7 = 0
Divide both sides by 7:
k = 3/7 or k^2 - 2 k + 7 = 0
Subtract 7 from both sides:
k = 3/7 or k^2 - 2 k = -7
Add 1 to both sides:
k = 3/7 or k^2 - 2 k + 1 = -6
Write the left hand side as a square:
k = 3/7 or (k - 1)^2 = -6
(k - 1)^2 = -6 has no solution since for all k on the real line, (k - 1)^2 >=0 and -6<0:
Answer: k = 3/7
