bowl a contains 2 red chips; bowl b contains two white chips and 1 red chip, and bowl c contains 1 red chip and 1 white chip. a bowl is selected at random, and one chip is taken at random from that bowl. if the selected chip is white, what is the probability that the chip belongs to bowl c?
Therefore the probability that the chip belongs to bowl c is 1/3.
What is the process of probability?Probabilities can be expressed as proportions with a 0–1 range or as percentages with a 0%–100% range. If an event has a probability of 1, it is very certain to occur; if it has a probability of 0, it has no chance of occurring. There are 45 chances out of 100 that an event will occur when its probability is 0.45 (45%).
Here,
A : 2 Red chips
B : 2 White chips
C: One Red and one White chip
P(selecting any bowl) = 1/3
1) We have to find P(W).
The selected chip can be white if it is either selected from Bowl B or Bowl C.
Symbolically this can be written as
P(W) = P(Bowl B and White chips) + P(Bowl A and White chips)
P(W) = [(1/3) × 1/1)] + [(1/3) × (1/2)]
P(W) = (1/3) + (1/6)
P(W) = 1/2
P(W) = 0.5
2) There is only one bowl with both of white and red chips and that bowl is bowl C. So it is possible the other chips in the bowl to red only if it has been selected from Bowl C.
So ,We need to find P(Bowl C | W).
P(Bowl C | W) = P(Bowl C and W)/P(W)
P(Bowl C | W) = (1/3) × (1/2)/(1/2)
P(Bowl C | W) = 1/3
Hence, the required probability is 1/3.

Answer:
D. Increase in assets
Step-by-step explanation:
The entry "Cash 750,000" is listed as a debit in the T-account because it is an increase in assets. In double-entry bookkeeping, a debit is used to record an increase in assets and a credit is used to record a decrease in assets. In this case, the business received cash in exchange for the airplane, which represents an increase in the business's assets. So the Cash account is debited and the Airplane account is credited.

you walk 45 m at an angle of 25 degrees s of e. then you walk 30 m north. what is the angle of the resultant vector?
So the angle of the resultant vector is approximately 53.13 degrees.
To find the angle of the resultant vector, you can use trigonometry to break the two vectors into their x and y components and then use the arctangent function to find the angle.
First, let's find the x and y components of the first vector (the one that travels 45 meters at an angle of 25 degrees south of east). To do this, we can use the trigonometric functions sine and cosine. The x component is equal to the distance traveled (45 meters) times the cosine of the angle (25 degrees), and the y component is equal to the distance traveled times the sine of the angle.
In this case, the x component of the first vector is 45 meters * cos(25 degrees) = 39.74 meters. The y component of the first vector is 45 meters * sin(25 degrees) = 22.36 meters.
Now let's find the x and y components of the second vector (the one that travels 30 meters north). The x component of this vector is 0 meters (since it doesn't move in the east-west direction), and the y component is 30 meters (since it travels 30 meters in the north direction).
To find the resultant vector, we can add the x components and y components of the two vectors. The x component of the resultant vector is 39.74 meters + 0 meters = 39.74 meters, and the y component of the resultant vector is 22.36 meters + 30 meters = 52.36 meters.
To find the angle of the resultant vector, we can use the arctangent function (also known as the inverse tangent function). The angle is equal to the arctangent of the y component divided by the x component.
In this case, the angle is equal to arctan(52.36 meters / 39.74 meters) = arctan(1.318) = 53.13 degrees.
So the angle of the resultant vector is approximately 53.13 degrees.

Find the x and y components of the initial vector first (the one that travels 45 meters at an angle of 25 degrees south of east). The trigonometric functions sine and cosine can be used to do this. The y component is equal to the distance traveled times the sine of the angle, and the x component is equal to the distance traveled times the cosine of the angle, or 45 meters times the cosine of the angle, or 25 degrees.
In this case, the x component of the first vector is 45 meters * cos(25 degrees) = 39.74 meters. The y component of the first vector is 45 meters * sin(25 degrees) = 22.36 meters.
The two vectors' x and y components can be added to determine the resultant vector. The resultant vector has two components: an x component of 39.74 meters plus 0 meters equals 39.74 meters, and a y component of 22.36 meters plus 30 meters equals 52.36 meters.
The arctangent function can be used to determine the angle of the resulting vector (also known as the inverse tangent function). The angle is determined by dividing the y component's arctangent by its x component.
In this case, the angle is equal to arctan(52.36 meters / 39.74 meters) = arctan(1.318) = 53.13 degrees.
So the angle of the resultant vector is approximately 53.13 degrees.

The area of a rectangle is 56.96 m²
If the length is 16, what is the width and perimeter?
Answer:
width is 3.56
Step-by-step explanation:
Area is = width x length
so Area/length
so 56.96/16=3.56
The width of the rectangle is 3.56 m and the perimeter is 39.12 m.
To find the width of the rectangle,
We need to use the formula for the area of a rectangle, which is:
Area = Length x Width
We know that the area of the rectangle is 56.96 m², and the length is 16 m. So,
We can substitute these values into the formula and solve for the width:
56.96 m² = 16 m x Width
Width = 56.96 m² / 16 m
Width = 3.56 m
Therefore, the width of the rectangle is 3.56 m.
To find the perimeter of the rectangle,
We need to use the formula:
Perimeter = 2 x Length + 2 x Width
We know that the length is 16 m and the width is 3.56 m,
So we can substitute these values into the formula and solve for the perimeter:
Perimeter = 2 x 16 m + 2 x 3.56 m
Perimeter = 32 m + 7.12 m
Perimeter = 39.12 m
Therefore, the perimeter of the rectangle is 39.12 m.
In conclusion, the width of the rectangle is 3.56 m and the perimeter is 39.12 m when the area is 56.96 m² and the length is 16 m.

Is an asymptote a continuous function?
An asymptote is a line that a curve approaches but never touches, so it is not part of the curve itself. As a result, an asymptote is not a function. However, the curve that approaches an asymptote may or may not be a continuous function.
A function is continuous if it is defined for all values in its domain and there are no breaks or jumps in the graph of the function.
For example, consider the function f(x) = 1/x. This function has a horizontal asymptote at y = 0, but it is not continuous at x = 0 because the value of the function is undefined at this point (division by zero is not allowed).
On the other hand, consider the function f(x) = ². This function has no asymptotes and is continuous for all values of x.

Determine the equation of the circle with center (0, -5) containing the point
(-√109,-6).
x^2 + y^2 - 10y + (-85) is equation of the circle with center (0, -5) containing the point (-√109,-6).
How do you find the equation of a circle?To find the equation of a circle with a given center and containing a given point, we can use the distance formula. The distance formula is given by:
d = √((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) is the center of the circle and (x2, y2) is the point on the circle. In this case, the center of the circle is (0, -5) and the point on the circle is (-√109, -6). Plugging these values into the distance formula, we get:
d = √((-√109 - 0)^2 + (-6 - (-5))^2)
d = √((-√109)^2 + (-1)^2)
d = √(109 + 1)
d = √110
Since the point (-√109, -6) is on the circle, the distance from the center of the circle to this point is the radius of the circle. Therefore, the radius of the circle is √110.
The equation of a circle with center (h, k) and radius r is given by:
(x - h)^2 + (y - k)^2 = r^2
In this case, the center of the circle is (0, -5) and the radius is √110, so the equation of the circle is:
(x - 0)^2 + (y - (-5))^2 = (√110)^2
x^2 + y^2 - 10y + 25 = 110
x^2 + y^2 - 10y + (-85) = 0

What are the three 3 semantics models of parameter passing for subprograms?
The three semantics models of parameter passing for subprograms are: in mode, out mode, and inout mode
In this question we need to describe the three semantics models of parameter passing for subprograms.
The three semantics models of parameter passing for subprograms are:
1) in mode: They can receive data from corresponding actual parameters.
2) out mode: They can transmit data to the actual parameter.
3) inout mode: They can do both.
There are two conceptual models of how data transfers take places in parameter transmission: either an actual value is copied (to the caller, to the callee, or both ways), or an access path is transmitted.
Generally, the access path is a simple pointer or reference.

The system of equations of line parallel to y = -5x + 4 is y = -5x + c where c is any arbitrary value of y-intercept.
The linear equation y = -5x + 4 is a straight line with slope -5 and y-intercept 4.
The slope of parallel lines are equal. So any line with slope -5 is parallel to the line y = -5x + 4. So the equation of a line with slope -5 is
y = -5x + c
where c is a constant
c represent arbitrary value of y-intercept.

How many angles are formed when 2 parallel line are split by a transversal?
When two parallel lines are cut by a transversal, eight angles are formed. Interior angles are supplementary to corresponding exterior angles and the sum of an interior and its corresponding exterior angle is 180 degrees.
Two parallel lines are cut by a transversal, eight angles are formed. Four of these angles are interior angles, which are the angles formed between the two lines and the transversal that lie within the region bounded by the parallel lines. The other four angles are exterior angles, which are the angles formed between the two lines and the transversal that lie outside the region bounded by the parallel lines.
