The probability of the prior event is multiplied by the current likelihood of the subsequent, or conditional, occurrence to determine the conditional probability.
What is conditional problems?The conditional probability is calculated by multiplying the probability of the previous event by the current probability of the subsequent, or conditional, occurrence. As an example, think about Event A: There is a 0.3 (30%) chance of rain today despite the fact that it is currently pouring outside.

Midsegments of triangles.
Question: Find TV
Answer:
14
Step-by-step explanation:
Since line MU = line MV, therefore line UV = 2 line MU.
Since line UL = line LT, therefore line UT = 2 line LT.
Now we know triangle MUL and triangle VUT are similar using SAS by a scale factor of 2. Since line TV is double the length of line ML.
Line TV 12*2 = 14.
Therefore line TV = 14.

The equation of the line is 3x - 7y + 51 = 0.
What are Parallel Lines ?
Coplanar, parallel lines that don't cross at any point are called parallel lines. Planes in the same three-dimensional space that never cross each other are said to be parallel.
Since the required line is parallel to the line that passes through (4,9) and (-3,6).
So, The slope will be equal to :
m = (y^2 - y^1) / (x^2 - x^1)
here, x^1 = 4, y^1 = 9, x^2 = -3 and y^2 = 6
∴ m = (6 - 9) / (-3 - 4)
= -3/-7
= 3/7.
We know that, The equation of a line is (y - y^1) = m (x - x^1)
∴ The equation of the required line will be :
y - 9 = 3/7 ( x - 4)
7y - 63 = 3x - 12
3x - 7y + 51 = 0.

Mi-Cha and her friends are going to a bounce music festival in New Orleans.
They decide to buy hoodies at the festival. A table showing the relationship between the number of hoodies and the total cost of the hoodies is shown.
The total cost is 16 times greater than the number of hoodies, hence option A is correct.
What is the average cost of an item?
The average price of products and services is the average cost. The average of these numbers will provide the average cost price when we have a number of nearly identical things to sell or purchase. It facilitates the purchasing and selling procedure for store owners.
The average cost is calculated as the sum of all product costs divided by the total number of goods. The word "average" is also used in math. The term "mean of data" refers to the average of any given set of data. The average, however, is thought to be the appropriate term in corporate contexts where profit and loss are crucial elements.
Given that,
1 hoodie costs $16
2 hoodies cost $32
3 hoodies cost $48
4 hoodies cost $64
5 hoodies cost $80
Thus, the relation between total cost and the number of hoodies can be found be dividing the cost upon the number of hoodies
∴ The relation = $80/5
Hence, cost of a hoodie is $16
We can say that option A, the total cost is 16 times greater than the number of hoodies.

A piece of Plexiglas has a width which is 5 centimeters shorter than its length. What represents the area of the Plexiglas, in terms of its length (L)?
Answer:
The area of the Plexiglas is given by the formula for the area of a rectangle, which is A = L * W, where L is the length and W is the width of the rectangle. In this case, the width is 5 centimeters shorter than the length, so we can represent it as W = L - 5. Substituting this expression for the width into the formula for the area, we get:
A = L * (L - 5)
This expression represents the area of the Plexiglas in terms of its length.

The sine and cosine of the angle of point P are sin θ = 143/145 and cos θ = -24/145 respectively. Option b. is the answer
How to determine the sine and cosine of the angle of point P?Given the coordinate of the point as P (-24/145, 143/145)
This implies x = -24/145 and y = 143/145
To determine the sine and cosine of the angle of point P, we can make a sketch using this information (see attached image).
opposite = 143/145, adjacent = -24/145
hypotenuse = √[(-24/145)² + (143/145)²] = √1 = 1
Using trigometric ratios:
sin θ = (143/145) / 1 = 143/145 [sin θ = opposite/ hypotenuse]
cos θ = (-24/145) / 1 = -24/145 [cos θ = adjacent/ hypotenuse]

Car X travels miles in 3 hours. a. Write the equation of the line that describes the relationship between distance and time. Use x for the time in hours and y for the distance in miles. b. What is the graph that represents the relationship between distance and time for Car X? Explain. Question content area bottom Part 1
The required equation would be y = 48x which describes the relationship between distance and time, where x is for the time in hours and y is for the distance in miles.
Car X travels 144 miles in 3 hours.
X represents the time in hours and y represents the distance in miles.
Move 3 units to the right of the origin using the slope and
144 unit(s) up to locate the spot
(3,144), which may be used to plot the connection.
Let the required linear equation be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
x₁ = 0, y₁ = 0
x₂ = 3, y₂ = 144
⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
Substitute values in the equation, we get
⇒ y - 0 = (144 - 0)/(3 -0 )[x -0]
⇒ y = (144/3)x
⇒ y = 48x
find the slope of the line with y=7x+2/3

you would find the difference between the ys and the XS then divide the product of those by [tex]\frac{y}{x}[/tex].
Given:-2x+3y=18 . When x has a value of zero, what is the value of y? When y has a value of zero, what is the value of x? What are these solutions called when they are graphed as part of the line -2x+3y=18? Complete your work in the space provided.
Answer:
When x has a value of 0, the equation -2x+3y=18 becomes 0+3y=18. Solving for y, we find that y=6.
When y has a value of 0, the equation -2x+3y=18 becomes -2x+0=18. Solving for x, we find that x=-9.
These solutions are called the x-intercept and the y-intercept, respectively, when they are graphed as part of the line -2x+3y=18. The x-intercept is the point where the line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. In this case, the x-intercept is (-9,0) and the y-intercept is (0,6). These points can be used to graph the line and to understand its slope and direction.
Step-by-step explanation:
Answer: 6, -9, ?
Step-by-step explanation:
When x has a value of zero:
-2x + 3y = 18
Substitute 0 into the value of x:
-2(0) + 3y = 18
We know that anything multiplied by 0 will always be zero, so you get:
3y = 18
Therefore, after dividing both sides by 3 to get y on its own, you get:
y = 6
When y has a value of zero:
-2x + 3y = 18
Substitute 0 into the value of y:
-2x + 3(0) = 18
We know that anything multiplied by 0 will always be zero, so you get:
-2x = 18
To get a positive number from a negative number x needs to be a negative number. Remember - and - makes +.
x = -9
