A and B are events defined on a sample space, with P(A) = 0.6 and P(BIA) = 0.3. then P(A and B) = 0.18
What is conditional probability?Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.
If A and B are events defined on the sample space with P(A) = 0.6 and P(BIA) = 0.3.
To find P(A and B),
we use the formula of conditional probability,
P( A and B ) = P (BIA) P(A)
P( A and B ) = 0.6 × 0.3
P( A and B ) = 0.18
Therefore, P ( A and B ) is 0.18.

Students to their LRN represent a one-to-one function.
If there is exactly one y in the range for every x in the domain of a function f, then that function is a one-to-one function. The range has no y equivalent to more than one x in the domain.
To put it another way, a function is referred to as a "one-to-one" function if various elements of A have different images in B. That is, there are various outputs for various inputs.
Here, each student has a different LRN or Learner Reference Number. No two students will have the same LRN. Therefore, this function is a one-to-one function. The correct option is C.

Triangles PQR and XYZ are similar triangles. Which are the other two angle measures of triangle XYZ?
The other two angle measures of triangle XYZ are 35° and 75°.
We are given that the triangles PQR and XYZ are similar.
Also, ∠ZXY = 70° and ∠PRQ = 35°.
Now, we know that when two triangles are similar, then the corresponding angles are same.
Therefore, ∠XZY = ∠PRQ = 35°
Now, in triangle XYZ, we have ∠XZY = 35° and ∠ZXY = 70°.
Since, we know that the sum of the angles of a triangle is 180°.
So, ∠XZY + ∠ZXY + ∠ZYX = 180°
i.e. 35° + 70° + ∠ZYX = 180°
i.e. ∠ZYX = 180° - ( 35° + 70° )
i.e. ∠ZYX = 180° - 105°
i.e. ∠ZYX = 75°
Hence, the other two angle measures of triangle XYZ are 35° and 75°.

The marked price of an article is Rs. 8000. After allowing a certain percent of discount with 13% Value Added Tax (VAT) levied, the articles is sold at Rs 7684. Find the difference between discount amount and VAT amount.
Answer:
$1200.00
Step-by-step explanation:
Let x = the discounted priced
x + .13x = 7684 Combine like terms.
1.13x = 7684 Divide both sides by 1.13
[tex]\frac{1.13x}{1.13}[/tex] = [tex]\frac{7684}{1.13}[/tex]
x = 6800
$6800 is the cost of the discounted article before tax.

The horizontal and vertical movement of the graph.
A vertical shift is a movement up or down the y-axis, and it's represented by a change in the value of the y-intercept. A horizontal shift is a movement left or right along the x-axis, and in the equation of a function it's a change in the value of x before it's multiplied by the slope.
Vertical Shifts
One simple kind of transformation involves shifting the entire graph of a function up, down, right, or left. The simplest shift is a vertical shift, moving the graph up or down, because this transformation involves adding a positive or negative constant to the function. In other words, we add the same constant to the output value of the function regardless of the input. For a function
g(x) =f(x)+k, the function f(x) is shifted vertically k units.
Horizontal Shifts
We just saw that the vertical shift is a change to the output, or outside, of the function. We will now look at how changes to input, on the inside of the function, change its graph and meaning. A shift to the input results in a movement of the graph of the function left or right in what is known as a horizontal shift,
Given a function f, a new function g(x)=f(x−h) , where h is a constant, is a horizontal shift of the function f . If h is positive, the graph will shift right. If h is negative, the graph will shift left.

This z-score tells you x = 34 is 2.75 standard deviations to the right of mean. And the mean is 23.
What is standard deviation?
The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the set mean.
Given:
Annie averages 23 points per basketball game with a standard deviation of 4 points.
Suppose Annie's points per basketball game are normally distributed.
Let X = the number of points per basketball game.

A random sample of 45 door-to-door encyclopedia salespersons were asked how long on average they were able to talk to the potential customer. Their answers revealed a mean of 8.5 minutes with a variance of 9 minutes.
Construct a 95% confidence interval for mu, the time it takes an encyclopedia salesperson to talk to a potential customer.
What is the upper confidence limit?
If the mean is 8.5 minutes and the variance is 9 minutes then the upper confidence limit is 9.3765 .
In the question ,
it is given that ,
the number of sales person in the random sample (n) = 45 ,
the mean = 8.5 minutes
the variance is = 9 minutes .
So , the standard deviation is = 3.

Find the dimensions of the rectangle of maximum area, with sides parallel to the coordinate axes, that can be inscribed in the ellipse given by x^2/144+y^2/16=1
The dimensions of the rectangle of maximum area are the length of 12√3 units and width of 4 units
How to find the dimensions of the rectangle of maximum area?
Given that the ellipse has the equation: x²/144 + y²/16 = 1
Make x the subject:
x²/144 + y²/16 = 1
(x²+9y²)/144 = 1
x² + 9y² =144
x² = 144-9y²
x = √(144-9y²)
The rectangle vertices is at (x,y), (-x,y), (x,-y), (-x,-y). Thus, the rectangle has a length and width of 2x and 2y respectively
The area of a rectangle inscribed inside an ellipse is given by:
Area (A) = 4xy
A = 4(√(144-9y²))y
A = 4y√(144-9y²)
A = 4√(144y²-9y⁴)
The maximum area of the rectangle is at dA/dy = 0
dA/dy = 4[144-18³y/ (√(144y²-9y⁴))]
4[144-18y³/ (√(144y²-9y⁴))] = 0
144-18y³= 0
18y³ = 144
y³ = 144/18
y³ = 8
y = ∛8
y = 2
x = √(144-9y²)
x = √(144 - 9(2)²)
x = √108
x = 6√3
Thus, the dimensions are the length = 2x = 2×(6√3) = 12√3 units, the width = 2y = 2×2 = 4 units

Set up a proportion
[tex]\frac{yellow}{total}[/tex] = [tex]\frac{yellow}{total}[/tex] Three of these numbers you know, Solve for the unknown
[tex]\frac{1}{3}[/tex] = [tex]\frac{x}{12}[/tex] Cross multiply and solve for x
3x = 12 Divide both sides by 3

what is the expression?
In the video, it was remarked that for small values of the equation of motion for the pendulum, 9 sin 0 = 0 is similar to the linear spring equation. If we take two nonzero terms of the L series for sin into account, the model is even more spring-like, but this time to a non-linear spring. From this perspective, which of the following kind of spring is the pendulum most like?
O ideal linear spring
O hard spring O soft spring
Hard spring
What is Spring?
They swing back and forth around a stationary point. Classic examples of this type of vibrating motion are a simple pendulum and a mass on a spring. The use of motion detectors demonstrates that the vibrations of these items have a sinusoidal character, even if this is not obvious from plain viewing.
Let θ be A,
[tex]A''+(g/l)sinA=0\\sinA=A - (A^{3} /3!)+(A^{5} /5!)....\\[/tex]
taking first 2 terms,
[tex]A'' +(g/l)(A-A^{3}/3!)\\[/tex]
intergrating both sides,
[tex]A'+(g/l)(A^{2}/2 -A^{4}/24)=c[/tex]
integrating again,
[tex]A+(g/l)(A^{3} /6-A^{5}/120)=ct+c_{1}[/tex]
power is 5= non linear spring
Additionally, a larger degree indicates that the displacement over time diminishes more quickly.
Hence its a hard spring.

Select all of the following equation(s) that are quadratic in form. x4 – 6x2 – 27 = 0 3x4 = 2x 2(x + 5)4 + 2x2 + 5 = 0 6(2x + 4)2 = (2x + 4) + 2 6x4 = -x2 + 5 8x4 + 2x2 – 4x = 0
The correct answer is option is a) x4 – 6x2 – 27 = 0 , d) 6(2x + 4)2 = (2x + 4) + 2 , e) 6x4 = -x2 + 5. as they are quadratic equations.
What are quadratic equations?A quadratic equation is a second-order polynomial equation in one variable using the formula x = ax2 + bx + c = 0 and a 0. The fundamental theorem of algebra ensures that it has at least one solution because it is a second-order polynomial problem. The answer could be straightforward or difficult.
How do you identify a quadratic equation?A quadratic function has the formula f(x) = ax2 + bx + c, with a, b, and c being integers and a not equal to zero. A parabola is a curve that represents the graph of a quadratic function. Parabolas can have openings that are upward or downward, different "widths" or "steepnesses," but they all share the same fundamental "U" form.
What is not quadratic equation?Due to the absence of an x2 component, bx 6 = 0 is NOT a quadratic equation. Because there is an x3 term, x3 x2 5 = 0 is NOT a quadratic equation (not allowed in quadratic equations).
The correct answer is option is a) x4 – 6x2 – 27 = 0 , d) 6(2x + 4)2 = (2x + 4) + 2 , e) 6x4 = -x2 + 5.
