P(A∩B)=1150,P(A|B)=1120,P(B)=?
Answers
For the given probabilities P(A∩B) = 1150 and P(A|B) = 1120, using Bayes' theorem for conditional probability, the probability of event B, P(B), is found to be approximately 1.027.
Explanation:The topic of this question is probability, specifically concurrent events in probability theory. Here, we use Bayes' theorem for conditional probability which states that P(A|B) = P(A ∩ B) / P(B).
Given that P(A∩B) = 1150 and P(A|B) = 1120, we can plug these values into the formula to find P(B). Hence, P(B) = P(A ∩ B) / P(A|B), substituting the given numbers, we get P(B) = 1150 / 1120 = 1.027 approximately.
So P(B), the probability of event B occurring, we would expect to be approximately 1.027 (or 102.7% assuming the probabilities were in decimal form to start with).

Alright, let's solve the problem with these given values.
The formula for calculating the probability of B in the context of A and B both happening is:
`P(A and B) / P(A|B)`.
In this case, the probability of A and B occurring is 1150, while the likelihood of A given that B has occurred is 1120. We can substitute these values into the formula:
So, P(B) = P(A and B) / P(A|B)
Substitute the given into the formula:
P(B) = 1150 / 1120 = 1.0267857142857142
Therefore, the Probability of event B (P(B)) is approximately 1.027 when rounded to three decimal places.

In triangle ABC, m∠A=55 triangle ABC, m∠A=55°, c=11c=11, and m∠B=19m∠B=19°. Find the perimeter of the triangle
Answers
Since a triangle has a total of 180° in interior angles, then angle C can be solved by
180° = A + B + C
C = 180° - 55° - 19°
C = 106°
Next, we use the Law of Sines. This law can be used in any type of triangle. This law states that there is a fixed ratio of side to sine of the opposite angle. In equation, that would be written as
a/sin A = b/sin B = c/sin C
Since, we know already side c and angle C, the fixed ratio is then,
11/sin 106° = 11.443
The last step is to apply ratio and proportion:
11.433 = a/sin 55°
a = 9.37 units
11.433 = b/sin 19°
b = 3.73 units
Thus, the perimeter of the triangle is
P = a + b + c
P = 9.37 +3.73 +11
P = 24.1 units

Which of the relationship below are function
Answers
For A, for example, the x value of 1 has 2 y values. For C, the x value of 7 has 2 y values as well, 10 and 3.
A functions B and D are valid functions because they meet the criteria of each x value having only one corresponding y value.
Function B: You mentioned that B is a function because each x value has only one corresponding y value. In mathematical terms, a function is defined as a relation between a set of inputs (x values) and a set of outputs (y values), where each input (x) maps to exactly one output (y). So, if B satisfies this definition, it is indeed a function.
Function D: Similar to B, if D also adheres to the definition of a function, where each x value corresponds to only one y value, then it is a function as well.
Function A: You mentioned that for A, the x value of 1 has 2 y values. In mathematical terms, a function cannot have one input (x) mapping to multiple outputs (y). If this is the case for A, it does not meet the definition of a function.
Function C: You mentioned that for C, the x value of 7 has 2 y values, 10 and 3. Again, if one input (x) is associated with multiple outputs (y) in C, it does not qualify as a function.
In summary, functions B and D are valid functions because they meet the criteria of each x value having only one corresponding y value. Functions A and C do not meet this criterion and are not functions in the mathematical sense.

The value of m in the following system of equations is:

n=m-2
A) m= -4
B) m= -6
C) m= 2
D) None of the choices are correct
Answers
m-2n=8, using n from above in this equation yields:
m-2(m-2)=8 perform indicated multiplication
m-2m+4=8 combine like terms on left side
-m+4=8 subtract 4 from both sides
-m=4 divide both sides by -1
m=-4
So the correct answer is A) m=-4
The correct option is A. [tex]m=-4[/tex]. By substituting the second equation into the first one in the system of equations, the value of m is -4.
The value of m in the system of equations can be found by substitution or elimination. Starting with the given equations:
[tex]m - 2n = 8 (1)[/tex]
[tex]n = m - 2 (2)[/tex]
Using the second equation (2) to substitute for n in the first equation (1):
[tex]m - 2(m - 2) = 8[/tex]
[tex]m - 2m + 4 = 8[/tex]
[tex]-m + 4 = 8[/tex]
[tex]-m = 8 - 4[/tex]
[tex]-m = 4[/tex]
[tex]m = -4[/tex]
This means that the value of m is -4, which corresponds to option A.

ILL GIVE BRAINLIEST !!!1 A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
Step 1: m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle)
Step 2: m∠w − m∠z = 90 degrees (corresponding angles)
Step 3: Therefore, m∠x + m∠y + m∠z = m∠w + m∠z
Step 4: So, m∠x + m∠y = m∠w
In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (sum of corresponding angles)
Step 2; it should be m∠w + m∠z = 180 degrees (supplementary angles)
Step 1; it should be m∠x + m∠y + m∠z = 90 degrees (corresponding angles)
Step 2; it should be m∠w + m∠z = 90 degrees (alternate exterior angle)

What are the two equations that need to be solved to find the solutions for the absolute value equation |2x-3|=x+6?
2x – 3 = x + 6 and 2x – 3 = –x – 6
2x – 3 = x + 6 and 2x + 3 = –x + 6
2x – 3 = x + 6 and 2x – 3 = x – 6
2x – 3 = x + 6 and 2x + 3 = x + 6
Answers
The equations to solve for [tex]\( |2x-3|=x+6 \)[/tex] are [tex]\( 2x - 3 = x + 6 \)[/tex] and [tex]\( 2x - 3 = -(x + 6) \).[/tex]
Let's solve the absolute value equation |2x-3|=x+6 step by step.
We'll start by writing down the equation:
|2x - 3| = x + 6
Since the absolute value expression |2x - 3| can be either positive or negative, we'll split the equation into two cases:
Case 1: 2x - 3 = x + 6
Case 2: 2x - 3 = -(x + 6)
Let's solve Case 1:
2x - 3 = x + 6
Subtract x from both sides:
2x - x - 3 = 6
Simplify:
x - 3 = 6
Add 3 to both sides:
x = 9
Now, let's solve Case 2:
2x - 3 = -(x + 6)
Distribute the negative sign:
2x - 3 = -x - 6
Add x to both sides:
2x + x - 3 = -6
Simplify:
3x - 3 = -6
Add 3 to both sides:
3x = -3
Divide both sides by 3:
x = -1
So, the solutions to the equation |2x-3|=x+6 are x = 9 and x = -1.

The answer is:
Sigma 960 (1/4)^i-1 ; the sum is 1280
Step-by-step explanation:We are given the first term of the geometric sequence as:
[tex]a_1=960[/tex]
Also, the common ratio of the terms in geometric sequence is: [tex]\dfrac{1}{4}[/tex]
We know that if the series is a geometric series than the sum of the terms is given by:
[tex]a+ar+ar^2+.....\\\\=a(1+r+r^2+....)\\\\=\sum ar^{n-1}[/tex]
where a is the first term of the series and r is the common difference.
Here a=960
and r=1/4
Hence,
The sum of the series is:
[tex]=\sum 960(\dfrac{1}{4})^{i-1}[/tex]
Now we know that the sum of the infinite geometric series is given by:
[tex]S=\dfrac{a}{1-r}[/tex]
where S is the sum of the series.
Hence, here the sum of the series is calculated by:
[tex]S=\dfrac{960}{1-\dfrac{1}{4}}\\\\\\S=\dfrac{960}{\dfrac{3}{4}}\\\\\\S=\dfrac{960\times 4}{3}\\\\\\S=1280[/tex]
Hence, the sum is: 1280

The prime factors are 2, 2, 3, 3, 5
Alternatively, you can draw up a factor tree like what you see in the attached image. The prime numbers are in the red boxes.
Either way, the prime factorization is
180 = 2*2*3*3*5
which can be written as
180 = 2^2*3^2*5
---------------------------------------------------------------------------
As for your second question, are you looking to simplify the square root of 180? If so, then follow these steps
sqrt(180) = sqrt(2*2*3*3*5)
sqrt(180) = sqrt(2^2*3^2*5)
sqrt(180) = sqrt((2*3)^2*5)
sqrt(180) = sqrt((2*3)^2)*sqrt(5)
sqrt(180) = 2*3*sqrt(5)
sqrt(180) = 6*sqrt(5)
sqrt stands for "square root"
