and wrote a different student's name on each. Two of the names were
boys and two girls. She put the four slips of paper in a bag and said
she is going to draw two slips out. She then drew the tree diagram
to show the different outcomes that are possible. "B" represents a
boy's name and "G" represents a girl's name. What is the theoretical
probability that the teacher draws two names that are the same sex?

1: We are two whole numbers less than or equal to 12.
Clue 2: Our least common multiple is 36.
Clue 3: Our greatest common factor is 1.What two whole numbers are we?
Answers
Answer:
Step-by-step explanation:
From clue one we know the numbers can be these because they add up to 12.
0 and 12 0+12=12
1 and 11 1+11=12
2 and 10 2+10=12
3 and 9 3+9=12
4 and 8 4+8=12
5 and 7 5+7=12
or 6 and 6 6+6=12
From clue two, we know the least common multiple is 36 so:
LCM of 0 and 12 -> NOT 36
LCM of 1 and 11 -> 11
LCM of 2 and 10 -> 10
LCM of 3 and 9 -> 9
LCM of 4 and 8 -> 8
LCM of 5 and 7 -> 35
LCM of 6 and 6 -> 6
none have a least common multiple of 36.
Please show clue 3 and make sure clue 2 is correct before I can finish.
The number with GCF 1 can be (2 and 3), (3, 4) and (4, 9)
what is Least Common Multiple?The smallest positive integer that is divisible by both a and b is known as the least common multiple (lcm), lowest common multiple (lcm), or smallest common multiple of two numbers a and b in mathematics and number theory.
Given:
1: We are two whole numbers less than or equal to 12.
Numbers are: 1, 2, 3, 4, 5,, 6, 7, 8, 9, 10, 11, 12
Clue 2: Our least common multiple is 36.
Number which have multiple 36 are: 2, 3, 4, 6, 9 , 12
Clue 3: Our greatest common factor is 1.
so, the number with GCF 1 can be (2 and 3), (3, 4) and (4, 9)

A: Translation left and up
B: Rotation 180 clockwise
C: Reflection over the x-axis
D: Translation right and down
Answers
Answer:
D. Translation right and down
Step-by-step explanation:
A: A translation left would keep the figure in the same quadrant. Moving left would just go off the graph, so it can't be this.
B: A rotation 180° would result in the vertices upside down. The shape would also be at different points, so this is incorrect.
C: A reflection over the x-axis would put the new figure directly underneath the original. This is not the case.

As we can see, they sell 2/5 as many white milks and chocolate milks. We can write this as the ratio 2:5. As you can see, we are given the total, which is 35. The total of the ratio in simplest form is 7 (2+5). As you can see, we have to multiply by 5 to get that 7 to 35. Therefore we multiply each part of the ratio by 5 to get our final answer. We can have w represent the white milks while c represents the chocolate milks.

At 2 hours before sunset, the temperature is 0°F. At 2 hours after sunset, the temperature is −4°F. Identify the equation representing the temperature y, in degrees Fahrenheit, at x hours after sunset.
y = ___ x + ___
Answers
Answer:
The answer is y = -4x + 0
Step-by-step explanation:
Because the temperature is -4 and when since zero is your starting point you do gown four which is why its negative and since zero is the start it would be the answer for y
For the given condition the equation represents the temperature y, in degrees Fahrenheit, at x hours after sunset will be y = -4x + 0.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, at 2 hours before sunset, the temperature is 0°F. 2 hours after sunset, the temperature is −4°F and the equation representing the temperature y, in degrees Fahrenheit, at x hours after sunset.
The equation is obtained as,
y = -4x + 0.
Thus, for the given condition the equation represents the temperature y, in degrees Fahrenheit, at x hours after sunset will be y = -4x + 0.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the solution set be S = { 4 }
a)
Let the equation be A
The value of A is
A = one fourth times x plus 17 equals 18
Substituting the values in the equation , we get
( 1/4 )x + 17 = 18
Now , when x = 4
( 1/4 )4 + 17 = 18
1 + 17 = 18
18 = 18
Therefore , the equation is true
b)
Let the equation be A
The value of A is
5 = 4y - 11
when y = 4
Substituting the values in the equation , we get
5 = 4 ( 4 ) - 11
5 = 16 - 11
5 = 5
Therefore , the equation is true
c)
Let the equation be A
The value of A is
-26 = 2( 3p - 5 )
when p = 4
Substituting the values in the equation , we get
-26 = 2 ( 3 (4) - 5 )
-26 = 2 ( 12 - 5 )
-26 = 2 ( 7 )
-26 ≠ 14
Therefore , the equation is false
d)
Let the equation be A
The value of A is
3 ( b + 4 ) = 24
when b = 4
Substituting the values in the equation , we get
3 ( 4 + 4 ) = 24
3 ( 8 ) = 24
24 = 24
Therefore , the equation is true
Hence , the equation -26 = 2( 3p - 5 ) is false

add 5x to both sides
11x - 8 = 4

now divide everything by 11
