What is the measure of < G
The measure of angle G is 34° because the sum of the measures of the angles GFE and GF is 180° - 28° = 152° and the measure of angle GFE is 28°, so the measure of angle GF is 152° - 28° = 34°.
What is angle?An angle is a shape formed when two lines or rays intersect. It is measured in degrees and is used in mathematics and geometry to describe the size and direction of a corner or turn. Angles measure the amount of turn between two lines, and can be described as either acute, obtuse, right, or reflex. Angles are also used to describe the orientation of objects in space, such as the position of the sun or the direction of a car relative to its surroundings.
The measure of angle GFE is 180° minus angle FEG, which is 180° - 28° = 152°. Since the sum of the measures of the angles of a triangle must equal 180°, the measure of angle GF is 180° - 152° = 28°. Therefore, the measure of angle G is 34° because the sum of the measures of the angles GFE and GF is 180° - 28° = 152° and the measure of angle GFE is 28°, so the measure of angle GF is 152° - 28° = 34°.

The distribution is skewed to the right.
How to find distribution is skewed?If the median is to the left of the center of the box and the right whisker is substantially longer than the left whisker in a box plot, then the distribution is skewed to the right.
This means that the majority of the data is clustered on the left side of the box plot and there are some extreme values on the right side that are causing the right whisker to be longer.
The median being to the left of the center of the box indicates that the data is not symmetric and is pulled to the left by the majority of the values.

The system of inequalities to represent the constraints of the situation are x ≤ 260, y ≤ 320, and x + y ≤ 360.
What is system of inequalities?A group of two or more linear inequalities are grouped together and graphed on a coordinate plane to discover the solution that concurrently solves all of the inequalities. Each inequality forms a half-plane on the coordinate plane, and the location where all the half-planes overlap is where the system is solved. Each point inside the feasible area meets all of the system's inequalities. This region is known as the feasible region. To identify the optimum solution given a set of constraints, systems of linear inequalities are frequently utilised in optimization issues.

After all the linking that will happen, there will be only one train left, moving at the speed of the slowest initial train.
If the three equally spaced trains had started in a different order, the final configuration would still be the same - one train moving at the speed of the slowest initial train.
On average, there will always be only one train left, regardless of the initial ordering of the trains. This is because after all the linking, the train with the slowest speed will always be at the front of the train and no other train can pass it.
If there are four equally spaced trains initially, after all the linking, there will be one train left moving at the speed of the slowest initial train. This is because any two faster trains that link up will then be slower than the train behind them, so the only train left will be the slowest one.

You roll a fair 666-sided die. What is \text{P(roll greater than 4})P(roll greater than 4)start text, P, left parenthesis, r, o, l, l, space, g, r, e, a, t, e, r, space, t, h, a, n, space, 4, end text, right parenthesis?
When a 666-sided fair die is rolled, then the probability of rolling greater than 4 is 0.9940 or 99.40%.
Given that the die is fair and has 666 sides. So, each face of the die will have a probability of 1/666, i.e.,
p(1) = p(2) = ... = p(666) = 1/666.
The probability of rolling greater than 4 is P(roll greater than 4), which is the sum of the probabilities of rolling a 5, 6, 7, 8, 9, ..., 666. So,
P(roll greater than 4) = p(5) + p(6) + p(7) + ... + p(666)
P(roll greater than 4) = (1/666) + (1/666) + (1/666) + ... + (1/666)
(There are 661 terms)P(roll greater than 4) = 661(1/666)
P(roll greater than 4) = 0.9940 (rounded to four decimal places)
Hence, the probability of rolling greater than 4 is 0.9940 or 99.40%.
Alternatively, the probability of rolling greater than 4 is
1 - P(roll less than or equal to 4)P(roll greater than 4)
= 1 - P(roll less than or equal to 4)P(roll greater than 4)
= 1 - (p(1) + p(2) + p(3) + p(4))P(roll greater than 4)
= 1 - (4/666)P(roll greater than 4)
= 1 - 0.0060P(roll greater than 4)
= 0.9940 (rounded to four decimal places)
Hence, the probability of rolling greater than 4 is 0.9940 or 99.40%.

Given ΔABC with measure of angle B equals 78 degrees, measure of angle C equals 52 degrees, and a = 16 inches, what is the length of b?
To find the length of side b in triangle ABC, we can use the Law of Sines. The length of side b is approximately 20.058 inches.
To find the length of side b in triangle ABC, we can use the Law of Sines. The Law of Sines states that the ratio of the length of a side to the sine of its opposite angle is constant for all sides and angles in a triangle.
Using the Law of Sines, we have:
sin(A)/a = sin(B)/b
We are given the measure of angle B as 78 degrees and side a as 16 inches. We can substitute these values into the equation:
sin(A)/16 = sin(78)/b
To find sin(A), we can use the fact that the sum of the angles in a triangle is 180 degrees:
A + B + C = 180
A + 78 + 52 = 180
A = 180 - 78 - 52
A = 50 degrees
Now we can substitute the values into the equation again:
sin(50)/16 = sin(78)/b
To solve for b, we can cross-multiply and isolate b:
b = (16 * sin(78))/sin(50)
We can calculate the length of side b by evaluating this expression using a calculator. The measurement will be roughly 20.058 inches.

The probability that the sample contains exactly 4 minorities is 0.0577
How to find the probability?We know that 25% of the employees of a large company are minorities. So, from any set of N employees that we ranodmly select from that large company, we can estimate that the number of minorities there is:
0.25*N
Now, we want to find the probability that the sample contains exactly 4 minorities.
Then we need to compute:
[tex]P = 0.25^4*0.75^3[/tex]
We also need to count the permutations for that probability, then we need to add the factor:
[tex]P = 0.25^4*0.75^3*(\frac{7!}{4!*3!} )[/tex]
Solving that we will get:
[tex]P = 0.25^4*0.75^3*(\frac{7!}{4!*3!} )\\\\P = 0.25^4*0.75^3*(\frac{7*6*5}{3*2} )\\\\P = 0.0577[/tex]

The sum of two numbers is 425. Find the two numbers if 20% of the first number is equal to 30% of the second number.
Answer:
Let's call the first number x and the second number y.
From the problem, we know that:
x + y = 425 (the sum of the two numbers is 425)20% of x = 30% of y (20% of the first number is equal to 30% of the second number)To solve for x and y, we can start by expressing one variable in terms of the other, using one of the equations.
Rearranging the first equation to solve for x, we get:
x = 425 - y
Now we can substitute this expression for x into the second equation, and solve for y:
0.2x = 0.3y (substituting x = 425 - y)
0.2(425 - y) = 0.3y (distributing the 0.2)
85 - 0.2y = 0.3y (combining like terms)
85 = 0.5y (adding 0.2y to both sides)
y = 170 (dividing both sides by 0.5)
So the second number is 170. To find the first number, we can substitute this value back into the first equation:
x + y = 425 (substituting y = 170)
x + 170 = 425
x = 255
Therefore, the two numbers are 255 and 170.
Give an algebraic proof for the triangle inequality ||v + w| < ||v|| + ||w|| Draw a sketch. Hint: Expand ||v + w||^2 = (v+w) · (v + w). Then use the Cauchy-Schwarz inequality.
An algebraic proof of the triangle inequality is ||u + v|| ≤ ||u|| + ||v||.
Let u and v be vectors in a vector space.
Using the properties of the inner product,
we have[tex],|u + v|² = (u + v) · (u + v)= u · u + u · v + v · u + v · v= |u|² + 2u · v + |v|²[/tex]
Now, take the square root of both sides of the above equation to get
|u + v| = sqrt(|u|² + 2u · v + |v|²) ≤ sqrt(|u|² + 2|u||v| + |v|²)= sqrt(|u|²) + sqrt(2|u||v|) + sqrt(|v|²) = |u| + |v|
Therefore, ||u + v|| ≤ ||u|| + ||v||. The equality holds if and only if u and v are linearly dependent.
Hence, the inequality is sometimes called the strict triangle inequality.

What is 252 divided by 9
Answer:
28 is the ans of 252÷9here we go
252 divided by 9 equals 28.
To divide 252 by 9, you can use long division, which involves dividing the number in steps until there is no remainder left.
Here's the step-by-step process:
Write down the dividend (252) and the divisor (9), and set up the long division format:
9 | 252
Look at the leftmost digit of the dividend (2) and see if it's divisible by the divisor (9). Since 2 is less than 9, we bring down the next digit (5) to the right of 2, making it 25.
9 | 252
2
Divide the new number (25) by the divisor (9). The result is 2, which is the first digit of the quotient. Multiply this result by the divisor (2 x 9 = 18) and write it below the 25, then subtract it from 25:
9 | 252
25
18
--
7
Bring down the next digit (2) from the dividend to the right of the remainder (7), making it 72. Now, divide 72 by 9, which gives you 8. Multiply this result by the divisor (8 x 9 = 72) and write it below the 72, then subtract it from 72:
9 | 252
25

It is false that Jayden substituted the wrong value for a. It is true that Jayden divided 14 by 2 and then added 1. 5. Jayden added inside the parentheses before multiplying.
1) The correct solution is
Given,
a ÷ (2 + 1. 5)
Substituting the value of a which is 14
= 14 ÷ (2 + 1. 5)
= 14 ÷ 3.5
= 4
2) As there is no term which needs to be divided so, the second statement is false.
3) Jayden didn't substitute the wrong value of a he just solved the given expression without considering the bracket and divided the 14 which is the value of a by 2.
4) Jyaden divided 14 by 2 and then added 1. 5. Jayden added inside the parentheses before multiplying.
i.e. a ÷ (2 + 1. 5)

which expression can be used to find the surface area??(see pic)
An expression which can be used to find the surface area of the triangular prism include the following: C. 2(1/2 · 3 · 4) + 4 · 2 + 3 · 2 + 5 · 2.
How to calculate the surface area of the triangular prism?In Mathematics, the surface area of a triangular prism can be calculated by using this mathematical expression:
Total surface area of triangular prism = (Perimeter of the base × Length of the prism) + (2 × Base area)
Total surface area of triangular prism = (S₁ + S₂ + S₃)L + bh
where:
b represent the bottom edge of the base triangle.h is the height of the base triangle.L represent the length of the triangular prism.S₁, S₂, and S₃ represent the three sides (edges) of the base triangle.By substituting the given parameters into the surface area of triangular prism formula, we have:
Surface area of triangular prism = Area (GFEH + BCEF + BIJC + ABF + ECD)
Surface area of triangular prism = 4 · 2 + 3 · 2 + 5 · 2 + (¹/₂ · 3 · 4) + (¹/₂ · 3 · 4)
Surface area of triangular prism = 2(1/2 · 3 · 4) + 4 · 2 + 3 · 2 + 5 · 2.

The blueprint of a triangular patio has side lengths 3.5 in., 3.5 in., and 5.25 in. If the shorter sides of the actual patio are each 10.5 ft long, how long is the third side?
The length of the third side of the actual patio is 15.75 feet.
What is similarity of triangle?In order to solve issues requiring proportional connections between the sides of two triangles, it is crucial to understand the idea of triangle similarity. If the matching sides and angles of two triangles are identical, then two triangles are said to be similar. When referring to similarities, the symbol is used.
Let us suppose the length of third side = x.
Given that, blueprint of a triangular patio has side lengths 3.5 in., 3.5 in., and 5.25 in.
Thus, the blueprint and the actual patio form two similar triangles.
The sides of the similar triangles are equal in ratio thus,
3.5/5.25 = 10.5/x
3.5x = 5.25 * 10.5
x = (5.25 * 10.5) / 3.5
x = 15.75
Hence, the length of the third side of the actual patio is 15.75 feet.

I buy a new TV. The tax rate is 8%. If the total I pay (including tax) is $799.20, how much was the TV before tax
Answer:
$735.264
Step-by-step explanation:
First, we need to find 8% of the total payment of the TV:
8% of $799.20
[tex]\frac{8}{100}[/tex] x $799.20
= $63.936
Finally, subtract $63.936 from $799.20:
= $735.264.
Therefore, if I bought a TV and the tax rate is 8% and the total payment of the TV is $799.20, the before tax of the TV is $735.264.
What is the percent change of 31 to 7
The percent change of 31 to 7 is found as 77.42% which is percent decrease of the number.
Explain about percent change?You can determine the amount of change that has occurred over this time period if you have data at two points in time. The outcome is known as the rate of change, sometimes known as the percentage change, and is given in percentage form (in absolute numbers, it really is merely a difference).
Using a percentage is one method of calculating a percent of change. Keep in mind that a percentage indicates "per 100." You can rephrase your problem as a % out of 100 by first describing the change as a fraction and measuring the amount of change to the original.
Original number = 31
Final number = 7
percent change = (7 - 31)/31 *100
percent change = - 24*100 / 31
percent change = - 77.42
Here negative sign shows the percent decrease of the number.
