Α.
P(B/A) = P(A)
B.
P(B/A) = P(B)
C.
P(B/A) = P(A) P(B)

To which subsets of the real numbers does the numbers -57 belongs?
Answer:
integer, rational number
Step-by-step explanation:
-57 is an integer because integers include negative and positive numbers that are not decimals or fractions. it is also a rational number because it can be converted into a fraction. these are subsets of the real numbers category.
a + 4 = 6, when a = 2. true false open
Answer:
True.
Step-by-step explanation:
[tex]a+4=6[/tex]
[tex]a=2[/tex]
To see if the equation would be correct given the value of [tex]a[/tex], we have to substitute:
[tex]2+4=6[/tex]
[tex]6=6[/tex]
Since both sides of the equation are equal, the statement is true.

what s the probality that the first card is a king and the second card is a king if the smapling is done withot replacement
Answer:
Total Probability = 1 / 221
Step-by-step explanation:
Total number of cards = 52
Total number of kings = 4
Probability (first card is a king) = 4 / 52
Probability (Second card is a king) without replacement = [4-1] / [52-1]
Probability (Second card is a king) without replacement = 3 / 51
Total Probability = [Probability (first card is a king)][Probability (Second card is a king) without replacement]
Total Probability = [4/52][3/51]
Total Probability = 12 / 2652
Total Probability = 1 / 221

Step-by-step explanation:
LHS = (tan β + Sec β)(1 - sin β)
= ((sin β / cos β) + (1/cos β))(1-sin β)
= ((1+ sin β)*(1- sin β))/cos β
= (1 - sin^2 β) / cos β

= cos β

Suppose that y varies directly with x and y=12 when x=-2. What is x when y=-6
Please help me!!
9514 1404 393
Answer:
x = 1
Step-by-step explanation:
You can work this several ways.
1) Consider the factor that gets you from the y-value of the known pair to the y-value of the unknown pair. Here, that factor is -6/12 = -1/2.
Then the unknown value of x is the known value multiplied by that same factor:
x = (-1/2)(-2)
x = 1
__
2) You can write the equation for a "varies directly" relationship and solve for the constant of proportionality. Then you can use that equation to find the unknown value of x.
y = kx . . . . . . . . . . . . . . y varies directly with x
k = y/x = 12/-2 = -6
Now we know ...
y = -6x
Filling in the new value for y, we have ...
-6 = -6x
1 = x . . . . . . divide by -6
__
3) You can write a proportion. Since we want to find a value for x, it is convenient to put that in the numerator.
-2/12 = x/-6
Multiplying by -6, we get ...
(-6)(-2)/12 = x = 1

Sanju wants to sell his artwork at a local fair. He has created 10 pieces of artwork and has spent $44 in creating them. He wants to make a profit of $300 at the fair. What is the price he needs to sell each piece to make that profit?
Answer:
30 dollars
Step-by-step explanation:
Sice he has to make a profit of 300 dollars if you divide 100 by to you get 30.If Sanju sells the artwork at 30 dollars he will make 300 dollars
The price Sanju needs to sell each piece to make a profit of $300 overall is $34.4.
What is profit?The profit is the difference between the selling price and the cost price of an item.
The cost of 10 pieces of artwork is,
Cost of producing 1 piece = $44/10 = $4.4
The Profit on 10 pieces of artwork is,
Profit of each piece = $300/10 = $30
The selling price of each piece of artwork is,
Selling price of each piece = Cost of production + Profit
= $30 + $4.4
= $34.4
Hence, the price Sanju needs to sell each piece to make a profit of $300 overall is $34.4.

Just one more question I need this in a step by step please
Answer:
2x+20+3x+40=90
5x+60=90
5x=30
x = 6
2x+20 = 2(6)+20
12+20
=32
3x+40 = 3(6)+40
18+40
=58
Answer:
Here we can first find the value of x simply by using the concept of corresponding angles.
As we know that angle with measurement 2x+20Degree and the right angle below are corresponding as we can consider the line (underlined in red) as a transversal intersecting lines underlined in green. {PLEASE SEE THE ATTACHMENT TO SEE THE HIGHLIGHTED LINES}
So, we get 2x+20 degree = 90 degree.
= 2x+20=90
= 2x=90-20
= 2x=70
= x= 70/2
= x=35 degree.
Now as we know the value of x we can find the other unknown angle by substituting it in the equation for the other angle.
Therefore, 3x+40degree= 3*35+40
105+40
= 145 degrees.

what is three blus six equal to
Answer:
Three plus six: 3 * 6
When we multiply x*y, we are summing x times the same number: y ory times the same number.(x)
In our case, we are summing three times six, so: 6 + 6 + 6 = 18
We could also say we are summing six times three: 3 + 3 + 3 + 3 + 3 + 3 = 18
Nowwe can say that 6 * 3 = 18

The expression using exponents we can rewrite as [tex]a^2 . c^2[/tex] .
What are exponents ?The number of times a number is multiplied by itself is referred to as its exponent. For instance, 2 to the third (written as [tex]2^3[/tex] ) means: 2 x 2 x 2 = 8. 2 x 3 = 6 does not equal [tex]2^3.[/tex] Keep in mind that a number raised to the power of one is itself.Exponentiation is the process of expressing huge numbers in terms of powers. That is, exponent refers to the number of times a number has been multiplied by itself.The key distinction is that an exponential function has its variable in the exponent, but a power function has its variable in the base.To learn more about exponent refer,
