I have two fair dice each numbered 1 to 6. I am going to throw the two dice. What is the probality that the sum of the numbers of the dice will be a square number?
Answer:
7/36
Step-by-step explanation:
It is given that we have two dice numbered from 1 to 6 . The maximum sum that can be obtained by rolling two dice is 6+6 = 12 and the minimum sum that can be obtained by rolling is 1+1 = 2 .
Now between 2 and 12 , the numbers which are perfect square are 4 and 9 .
Getting a sum of 4 :-
We can get a sum of four from two dice as ,
1 on first dice, 3 on other.2 on first dice , 2 on other.3 on first dice , 1 on other.Getting a sum of 9 :-
3 on first dice, 6 on other.6 on first dice, 3 on other.4 on first dice, 5 on other.5 on first dice, 4 on other.So there are a total of 7 possibilities by which we can can get a perfect square number by rolling two dices .
Now total number of possible outcomes = 6*6 = 36 .
Henceforth the required probability would be ,
[tex]\rm\implies P( getting \ a \ square\ number) =\dfrac{Total \ number\ of \ favourable\ outcomes}{Total \ number \ of \ possible \ outcomes} [/tex]
[tex]\rm\implies \underline{\underline{\red{ P( getting \ a \ square\ number)=\dfrac{7}{36}}}}[/tex]
Hence the required probability is 7/36 .
The probability of getting a square number as the sum is therefore 7/36.
WHAT IS PROBABILITY ?
Probability is a branch of mathematics that deals with the study of random events or phenomena. It involves analyzing the likelihood of an event occurring, given the conditions or circumstances that surround it. Probability is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event is determined by dividing the number of favorable outcomes by the total number of possible outcomes. Probability is widely used in many fields, including statistics, physics, finance, engineering, and social sciences, to name a few.
There are 36 possible outcomes when two dice are thrown since each die has 6 possible outcomes.
Let's find the possible outcomes where the sum of the numbers on the dice is a square number. The only possible sums that are squares are 4, 9 and 16.
To get a sum of 4, the dice must land on 1 and 3 or 3 and 1. There are two possible ways of doing this, so there are 2 outcomes.
To get a sum of 9, the dice must land on 3 and 6, 4 and 5, 5 and 4, or 6 and 3. There are four possible ways of doing this, so there are 4 outcomes.
To get a sum of 16, the dice must both land on 6. There is only one possible way of doing this, so there is 1 outcome.
Therefore, there are 2 + 4 + 1 = 7 outcomes where the sum of the numbers on the dice is a square number.
The probability of getting a square number as the sum is therefore 7/36.

The measure of an angle is twice less than that of its supplement angle.
The supplementary angle will be 60°.
What are supplementary angles?
Supplementary angles are angles (only two) whose sum is equal to 180 degrees. In other words, if we add two angles together and the result is 180 degrees, those angles are considered supplementary.
For example, if we have angle A that measures 60 degrees, its supplement angle B will measure 120 degrees (180 - 60 = 120). Angles A and B are supplementary angles.
Supplementary angles can be adjacent, meaning they share a common vertex and side, or they can be non-adjacent. In either case, their sum will always be 180 degrees.
Supplementary angles are commonly used in geometry and trigonometry to solve problems related to angles and triangles.
Now,
Let x = measure of the angle.
Then, the supplement angle is 180 - x.
According to the problem, x is twice less than the supplement angle. In other words, the supplement angle is twice greater than x. We can write this as:
180 - x = 2x
Solving for x, we get:
180 = 3x
x = 60
Therefore, the angle measures 60 degrees.

The circle below is divided into six equal pieces. If the area of the shaded region is 98pi what is the
circumference of the circle? Leave answer in terms of pi
Consequently, the circle's diameter is 28π√3.
What is its the circumference?The radius of a circular or other curved geometry form refers to its length. It is the border across any two-dimensional circle surface measured linearly in one dimension.
Since the circle is divided into six equal pieces, the shaded region represents one-sixth of the total area of the circle. Therefore, the total area of the circle can be found by multiplying the shaded area by 6:
Total area of circle = 6 × 98π = 588π
The formula for the area of a circle is A = πr², where r is the radius of the circle. Solving for r, we get:
r² = A / π = 588π / π = 588
r = √588 = 2√147 = 2√3 × √49 = 14√3
C = 2r is the method for calculating a circle's diameter. Plugging in the value of r, we get:
C = 2π(14√3) = 28π√3
Therefore, the circumference of the circle is 28π√3.

Barbie should build a roof support that is 4√7 inches high to fit the slanted roof perfectly on her dream house.
Describe Pythagorean theorem?The Pythagorean theorem is a fundamental theorem in mathematics that describes the relationship between the three sides of a right-angled triangle. It is named after the ancient Greek mathematician Pythagoras, who is credited with its discovery.
The theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Mathematically, this can be expressed as:
a² + b² = c²
where a and b are the lengths of the two shorter sides of the triangle (called the legs), and c is the length of the hypotenuse.
The Pythagorean theorem has important implications in geometry, trigonometry, and other branches of mathematics. It is also widely used in a variety of real-world applications, such as architecture, engineering, and physics. For example, it can be used to calculate the distance between two points in a two-dimensional plane, the height of a building or a tree, or the length of a diagonal in a rectangle or a square.
To solve this problem, we need to use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the legs (the two shorter sides) is equal to the square of the length of the hypotenuse (the longest side).
In this case, the two legs of the right triangle are the height of the roof and half the width of the house (since the roof slants down from the center of the house). The hypotenuse is the length of the roof, which is 16 inches on both sides.
So, we can set up the equation:
(height)² + (12)² = (16)²
Simplifying and solving for the height:
(height)² = (16)² - (12)²
(height)² = 256 - 144
(height)² = 112
height = √112
Using a calculator or simplifying by hand, we find that:
height = 4√7 inches
Therefore, Barbie should build a roof support that is 4√7 inches high to fit the slanted roof perfectly on her dream house.

We can see that the height of the tent (h) forms one leg of a right triangle, with the base (b) being half of one of the equal sides of the isosceles triangle. We can use the angle at the peak of the tent (103 degrees) to find the height using the tangent function:
tan(103) = h/b
To find b, we can use the fact that the equal sides of the isosceles triangle are 163 cm long, so b = 163/2 = 81.5 cm.
Now we can plug in b and the angle measure into the tangent equation and solve for h:
tan(103) = h/81.5
h = 81.5 * tan(103)
h ≈ 370.5 cm

The value of x that makes A parallel to B is 15.
Describe Alternate Exterior Angles?Alternate exterior angles are a pair of angles that lie outside of two parallel lines and are on opposite sides of the transversal. In other words, they are a pair of non-adjacent angles that are formed when a transversal intersects two parallel lines. The angles are congruent, meaning that they have the same measure.
The term "alternate" refers to the fact that they are on opposite sides of the transversal and "exterior" indicates that they are outside of the parallel lines. Alternate exterior angles are important in geometry because they can be used to prove that two lines are parallel. If the alternate exterior angles are congruent, then the lines are parallel.
Since the alternate exterior angles are equal, we can set them equal to each other:
8x + 30 = 10x
Subtracting 8x from both sides, we get:
30 = 2x
Dividing both sides by 2, we get:
15 = x

The Gordon family plans to buy a TV. One TV has a purchase price of $330 and an estimated yearly operating cost of $14. The other has a purchase price of $369 and an estimated yearly operating cost of $9. Which TV should the Gordons buy if they plan to keep it for 8 years? Use rational functions to help justify your answer.
ANSWER:rational functions that model the average annual cost of each television if it is owned for x years, such as f(x)= (330+14x)/x and
g(x)= (369+9x)/x
calculation proving that over 8 years, the annual cost for the $330 television is $55.25; for the $369 television, it is $55.13
statement that the Gordons should buy the $369 television because it is less expensive overall
step by step: edge 2023
Answer:
The Gordon's should buy TV2
Step-by-step explanation:
To determine which TV the Gordons should buy, we need to compare the total cost of each TV over the 8-year period. Let's define some variables:
- Let x be the number of years the TV is used.
- Let y1 be the total cost of TV 1 over x years.
- Let y2 be the total cost of TV 2 over x years.
- Let P1 be the purchase price of TV 1.
- Let P2 be the purchase price of TV 2.
- Let O1 be the annual operating cost of TV 1.
- Let O2 be the annual operating cost of TV 2.
Using these variables, we can write the following equations:
y1 = P1 + x * O1
y2 = P2 + x * O2
To compare the total cost of each TV over 8 years, we need to find y1 and y2 when x = 8. Plugging in the given values, we get:
y1 = 330 + 8 * 14 = 462
y2 = 369 + 8 * 9 = 441
Therefore, the total cost of TV 1 over 8 years is $462, and the total cost of TV 2 over 8 years is $441. Since TV 2 has the lower total cost, the Gordons should buy TV 2.
From a mathematical standpoint, we can also use rational functions to analyze this problem. The total cost of each TV is a linear function of x, so we can write:
y1(x) = P1 + x * O1
y2(x) = P2 + x * O2
The ratio of these functions is:
y1(x) / y2(x) = (P1 + x * O1) / (P2 + x * O2)
To determine which TV is cheaper over 8 years, we need to compare the ratios when x = 8:
y1(8) / y2(8) = (330 + 8 * 14) / (369 + 8 * 9) ≈ 1.051
Since this ratio is greater than 1, TV 1 is more expensive than TV 2 over 8 years. Therefore, the Gordons should buy TV 2.

type of measurement enables learners to quantify the measurement of an object, but differs in amount each time.
Answer:
variable measurement
Step-by-step explanation:
The type of measurement you are referring to is called "variable measurement". In variable measurement, the quantity being measured can vary from one observation to another. This means that the measurement is not consistent or fixed, and can change each time it is taken. An example of variable measurement is measuring the weight of a person over time, as their weight can change from one day to another. Another example is measuring the temperature in a room throughout the day, as the temperature can fluctuate based on factors such as sunlight, air conditioning, and human activity.

perpendicular to YZ. Therefore, triangle XYZ Select Choice is not or is a right triangle.
Answer: slope of XY is not perpendicular to YZ. Therefore, triangle XYZ is a right triangle.
Step-by-step explanation:
The slope of a line passing through two points (x1, y1) and (x2, y2) is given by (y2 - y1) / (x2 - x1).
Using this formula, we can find the slopes of the three sides of triangle XYZ:
Slope of XY = (2h - 0) / (2h - 0) = 1
Slope of YZ = (0 - 2h) / (4h - 2h) = -h / h = -1
Slope of ZX = (0 - 0) / (4h - 0) = 0
Therefore, the slope of XY is 1, the slope of YZ is -1, and the slope of ZX is 0.
Since the product of the slopes of two perpendicular lines is -1, we can see that the slope of XY and the slope of YZ are negative reciprocals of each other, which means that they are perpendicular. Therefore, triangle XYZ is a right triangle.

What is a polar form ?
In mathematics, the polar form is a way of representing complex numbers using their magnitude and angle. A complex number can be represented in the form r(cos θ + i sin θ), where r is the magnitude (or modulus) of the complex number, and θ is its argument (or phase angle). Alternatively, the polar form can be represented in terms of magnitude and angle as r ∠θ, where r is the magnitude and θ is the angle in radians. This form is also known as the exponential form of a complex number. The polar form is useful in calculations involving complex numbers, especially in multiplication and division, where it is often easier to work with the polar form rather than the rectangular form (a + bi).
D. 5√2∠63.4°
To convert a complex number from rectangular form to polar form, we use the following formulas:
r = √(a^2 + b^2)
θ = tan^-1 (b/a)
Where a and b are the real and imaginary parts of the complex number, respectively.
In this case, a = 1 and b = 2, so:
r = √(1^2 + 2^2) = √5
θ = tan^-1 (2/1) = 63.4°
Therefore, 1 + 2i in polar form is 5√2∠63.4°.

The tens digit in a dividend is less than the divisor. The divisor has one digit. Gracie says the quotient must have a 0 in the tens place. Is Gracie correct? Explain
Gracie's statement is not necessarily correct about the tens digit in a dividend is less than the divisor and the divisor has one digit. Gracie says the quotient must have a 0 in the tens place.
What is dividend?
In mathematics, a dividend is the number that is being divided in a division problem. For example, in the division problem 18 ÷ 3 = 6, 18 is the dividend.
Gracie's statement is not necessarily correct. Let's look at a couple of examples to see why.
Example 1:
Dividend = 25
Divisor = 4
In this case, the tens digit of the dividend (2) is less than the divisor (4). The quotient is 6 with a remainder of 1. There is no 0 in the quotient, so Gracie's statement is incorrect.
Example 2:
Dividend = 35
Divisor = 4
In this case, the tens digit of the dividend (3) is also less than the divisor (4). The quotient is 8 with a remainder of 3. Again, there is no 0 in the quotient, so Gracie's statement is still incorrect.
From these examples, we can see that Gracie's statement is not always true. It is possible for the tens digit of the dividend to be less than the divisor, and for the quotient to not have a 0 in the tens place.
The only time Gracie's statement would be true is if the remainder is 0 after dividing the dividend by the divisor. In that case, the quotient would indeed have a 0 in the tens place. However, this is not always the case.
