Step-by-step explanation:
George and Lea each toss a tetrahedral die with faces numbered 1 through 4, and then multiply the two resulting numbers. If the product is less than 9, George wins; otherwise, Lea wins. What is the probability that Lea will win? Express your answer as a common fraction.
Answer:
I think the total number of combinations of 3 from 6 = 6C3 = 20
All possible combinations of 3 which have a product divisible by 3 must contain either a 3 or a 6.
So the number not divisible must be 3 combinations from the number 1, 2, 4, and 5.= which is 4
So the required probability is 20-4 ? 20 = 16/20 = 0.8 Answer
Hope this help you! :)

Given a triangle with side lengths of a, b, and c, where c is the longest side, which statement is true?
Answer:
If a^2 + b^2 =c^2, then the triangle is a right triangle.
Step-by-step explanation:
Given
Shape: Triangle
Sides: a, b, c
Longest: c
Required
Select the true statements (See comment section for options)
From the options, we can see that we need to prove if the triangle is right-angled or not.
Since side c is the longest side, it means that side c is the hypotenuse.
Applying Pythagoras theorem
We have that:
[tex]a^2 + b^2 = c^2[/tex]
If the above mathematical statement is true, then the triangle is right-angled
Answer:
If a^2 + b^2 =c^2, then the triangle is a right triangle.

Answer:
Mean: 29.6
MAD: 10
Step-by-step explanation:
Answer:
Mean = 29.6
MAD = 10
Step-by-step explanation:
For the mean, just add all of the points together and divide it by 10 since there are 10 games.
For the MAD, use the mean and subtract is from each of the games. As an example, just do 23-29.6 and ignore if it is a negative sign. Do it for all and then add up the leftovers. Then divide it by the 10 games.
(6.6+1.4+1.6+8.4+10.6+8.4+15.4+4.6+26.6+16.4)/10

Cooper and yu are adding fractions, 1/3, 7/9, and 4/15. Their first step is to find the least common denominator of 3, 9, and 15. Is either of them correct? Explain your reasoning
Answer:
Yes
Step-by-step explanation:
When adding fractions which have unequal denominator values, the first step is to find a way in which all the denominators conform to a common denominator value which is achieved by obtaining the lowest common factor of the denominator values.
The L. C. M of 3, 9 and 15 is : 45
1/3 + 7/9 + 4/15
Npq we have a common denominator value :
(15 + 35 + 12) / 45
= 62 / 45

The system of equations for each point are mentioned below.
What is a mathematical function, equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is to find two systems of linear equations that have the given point as a solution.
For the point (- 2, 1), we can write the system of equations as -
1 = - 2m₁ + c₁
1 = - 2m₂ + c₂
For the point (3, - 2), we can write the system of equations as -
- 2 = 3m₁ + c₁
- 2 = 3m₂ + c₂
For the point (0.5, 1), we can write the system of equations as -
1 = (1/2)m₁ + c₁
1 = (1/2)m₂ + c₂
For the point (0, 4), we can write the system of equations as -
4 = c₁
4 = c₂
Therefore, the system of equations for each point are mentioned above.

ABC is a right-angled triangle.
Calculate the length of BC.
Give your answer correct to 1 decimal place.
Answer:
14.5
Step-by-step explanation:
The pythagoreom theorum shows a^2 + b^2 = c^2. Therefore, c^2 - a^2 = b^2
256 - 44.89 = 211.11
The square root of 211.11 rounded to the first decimal place is 14.5
The length of BC is 14.5 cm
What is Pythagoras theorem?The Pythagoras theorem states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Given
AB = 6.7 cm
AC = 16 cm
According to the Pythagoras theorem of triangles
[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]AB^{2} +BC^{2} =AC^{2}[/tex]
[tex]BC^{2} =AC^{2} -AB^{2}[/tex]
[tex]BC ^{2} =16^{2}-(6.7)^{2}[/tex]
[tex]BC = \sqrt{16^{2} -(6.7)^{2} }[/tex]
BC = 14.5 cm
Hence, the length of BC is 14.5 cm

A ceiling fan has 2.8 ft for the radius what is the circumference?
A water bottle cap has 13 mm for the radius what is the circumference?
A bowl has 56.5 cm for the circumference what is the radius?
A drum has 75.4 in for the circumference what is the radius?
Answer:
1. 17.59
2. 81.68
3. 8.99225
4. 12.00028
Step-by-step explanation:
for the first two you have to multiply the radii by 2 to find the diameter, then multiply your diameter by pi (3.14) to find the circumference
for the second two you have to work backwards so you have to divide the circumference by pi (3.14) which will give you the diameter, then you have to divide the diameter by 2 to get the radius.

Six times the lesser of the two consecutive even integers is 4 times the greater even integer. What are the integers?
Answer:
Integers are 4 and 6
Step-by-step explanation:
Let the two consecutive even integers be [tex]x,x+2[/tex] such that [tex]x<x+2[/tex]
Six times the lesser of the two consecutive even integers is 4 times the greater even integer.
So,

Answer: x=73 y=73 z=107
Step-by-step explanation:
The angel of x is 73° because opposite angles are always the same.
The angle of y is also 73° because it is on a parallel line so angles on a parallel line would be the same.
Then the angle of z is 107° because the other side of z would be 73° so you need to deduct this from 180° (because a straight line always adds up to 180°).
How are the semicircle and the diameter of a circle related?
The length of the diameter and the length of semicircle are the same.
The degree measure of the diameter and the degree measure of the semicircle are the same.
The angle measure of the diameter is twice the angle measure of the semicircle.
The angle measure of the diameter is half the angle measure of the semicircle.
Answer:
B. The degree measure of the diameter and the degree measure of the semicircle are the same.
Step-by-step explanation:
Semicircle and diameter in a circle are related because the degree measure of the diameter and the degree measure of the semicircle are the same.
Diameter:
The diameter of a circle is the the line that passes through the centre of a circle and meets the circumference at opposite end. The diameter divides a circle into semi circle. Therefore, the degree measure is 180 degrees.
Semi CircleSemi Circle is half of a circle. It is from the diameter of a circle you cut out a semi circle. The degree measure of a circle is 360 degree while the degree measure of half of a circle(semi circle) is 180 degrees.
Therefore, the degree measure of the diameter and the degree measure of the semicircle are the same.
