An ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots)., Imagine that such a die is rolled twice in succession
and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment.
Compute the probability of each of the following events.
Event A: The sum is greater than 9.
Event B: The sum is an odd number.
Write your answers as fractions.
5/36 is the probability that the sum will be bigger than 9, and 9/36 is the likelihood that the number will be divisible by either 5 or 6.
How to calculate a probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Probability has been incorporated into mathematics to predict the likelihood of different events.
Mathematics' study of random events is known as probability, and there are four primary types of probability: axiomatic, classical, empirical, and subjective. Since probability is the same as possibility, you could say that it is the likelihood that a specific event will occur.
Given ,
It may take the following forms:
(4,6),(5,5),(5,6),(6,5),(6,6)
The likelihood that the total exceeds 9 is 1/36+1/36+1/36+1/36+1/36
=5/36.
B) It can occur in the following ways:
(1,4),(4,1),(3,3),(3,2),(4,2),(5,1),(1,5),(6,4),(4,6)
the probability that the number is getting divisible by 5 or 6 or both is

the sampling distributions used for both matched/related/paired samples and independent samples statistical tests have what value at the center of the distribution for hypothesis testing?
The sampling distributions are used for statistical tets.
What is sampling distributions?A sampling distribution, also known as a finite-sample distribution, in statistics is the probability distribution of a particular statistic based on a random sample. The sampling distribution is the probability distribution of the values that the statistic takes on if an arbitrarily large number of samples, each involving multiple observations (data points), were used separately to compute one value of a statistic (such as, for example, the sample mean or sample variance) for each sample. Although only one sample is frequently observed, the theoretical sampling distribution can be determined.The use of sampling distributions in statistics is crucial because they significantly simplify the process of drawing conclusions from statistical data. They specifically enable analytical considerations to be based on a statistic's probability distribution rather than the joint distribution of the data.Hence,The sampling distributions are used for statistical tets.

In the question ,
it is given that ,
let x be the number of miles they drive together and pay the same amount.
the charge for Lena's car rental company is $50 per day and then $0.40 per miles which is represented by the equation
Cost = 50 + 0.40x

How do I make sure a parabola(quadratic function) equation goes through specific points using standard form? An example is an equation that goes through the points (-4,0), (3,0) and (2,-18).
NO TROLLS, PLEASE!
An equation that goes through the given points is [tex]y=3x^{2} +3x-36.[/tex]
What is the parabola equation?
A parabola is a graph of a quadratic function. An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola. The parabola's fixed line and fixed point are together referred to as the directrix and focus, respectively.
Given points are (-4,0), (3,0), and (2,-18).
The equation of a parabola is [tex]y = \frac{1}{4 \left(f - k\right)} \left(x - h\right)^{2}[/tex]
Since the point (−4,0) lies on the parabola, then [tex]0 = \frac{1}{4 \left(f - k\right)} \left(-4 - h\right)^{2} + k[/tex]
Since point (3,0) lies on the parabola, then [tex]0 = \frac{1}{4 \left(f - k\right)} \left(3 - h\right)^{2} + k[/tex]
Since point (2,−18) lies on the parabola, then [tex]-18 = \frac{1}{4 \left(f - k\right)} \left(2 - h\right)^{2} + k[/tex]
Solving the above all three systems, we get that [tex]h= -\frac{1}{2} , k = - \frac{147}{4}, f = -\frac{110}{3}[/tex]
Substituting the above value in the equation of a parabola, we get

each side of a square is increasing at a rate of 2 cm/s. at what rate is the area of the square increasing when the area of the square is 81 cm2?
The area of the square is increasing at a rate of 36 cm/s2.
What is the rate of expansion of a solid?
For physics, The term "thermal expansion" refers to a material's change in length, width, height, or volume when its temperature is raised or lowered. Solids exhibit particularly noticeable thermal expansion due to their closely packed atoms. There are numerous uses for the thermal expansion of solids in daily life.
A solid's atoms vibrate more quickly around their fixed positions when it is heated. As a result, there is little relative growth in the size of solids during heating. In order to prevent buckling when exposed to heat from the sun, metal train tracks feature tiny gaps.
Calculation
L = length of a side
A = L2
dA/dt = 2L dL/dt
dL/dt = 2 cm/s
A = 81 sqcm ⇒ L = √A = √81 cm = 9 cm
dA/dt = 2(9cm)(2 cm/s) = 36 sqcm
Hence the rate is the area of the square increasing is 36sqcm

Using the rate of change of area ,
If the area of a square is 81 cm² the area of the square increases at a rate of 36 cm²/s.
Suppose that initially there were no squares, but suddenly squares began to form at a constant rate. At the end of the first second, the sides were 2 cm long each, and at the end of the second second they were 4 cm each. Therefore, we can say that the rate of change of increasing sides is 2 cm/s. If a square has a side of S cm, this is expressed mathematically.
dS/dt = 2 cm/s ---(1)
Since we know the area of the square is given by
A=S² cm²
the derivative of the area function shows the variation of area with respect to side S
dA/dS=2S
So , when area of square is 81 cm² , its side length is 9 cm. Since we need rate of change of area w.r.t. time, we need to multiply both the sides by dS/dt .
dA/dS×dS/dt=2S×dS/dt
=> dA/dt=2S×dS/dt
=> dA/dt = 2×9 ×2 = 36 cm²/s
Hence, the required area increasing rate is 36 cm²/s.

The lengths of the four sides of a quadrilateral (in feet) are consecutive even integers
If the perimeter is 92 feet, find the value of the longest of the four side lengths.
The value of the longest of the four side lengths is 26 feet.
How to calculate the value?Let the integers be x, x + 2, x + 4 and x + 6.
Since the perimeter is given as 92 feet. This will be:
x + x + 2 + x + 4 + x + 6 = 92
4x + 12 = 92
Collect like terms
4x = 92 - 12
4x = 80

x = 80 / 4
x = 20

x = -13 ± (√ 565) / 22 is the solution to the operation
(8x² + 8x - 9) + (3x² + 5x) = 0.
∴ (8x² + 8x - 9) + (3x² + 5x) = 0
=> 8x² + 8x - 9 + 3x² + 5x = 0
=> 11x² + 13x -9 = 0
After obtaining the standard form a, b and c are identified from the original equation and are placed into the quadratic formula.
∴ x = (-b±√(b²-4ac))/(2a)
11x² + 13x -9 = 0
where,
a = 11, b = 13, c = -9
=> x = (-13 ± √(13² - 4×11(-9)) )/ (2×11)
=> x =( -13 ± (√ 565) )/ (22).
