If Ef bisects CD, CG = 9x - 4, GD = 2x + 31, EF = 4x - 1, and GF = 7, find EG
The value of EG is 12
In geometry, the term line segment is defined as the part of a line segment used to join two points in a plane. When segments join the midpoints of two sides of a triangle, the segments are parallel to the other side and represent one half of it.Given equations of line are :
CG = 9x -4
GD = 2x+31
EF = 4x-1
GF = 7
We are asked to find the length of EG. We can start by analyzing the bisector, CD. Since the segment is the bisector, So CG = GD.
CG = GD
9x -4 = 2x+31
7x = 35
x = 5
Analyzing EF
EF = EG + GF
4x-1 = EG +7
20 - 1 -7 = EG
EG = 12
The value of EG is 12

What is place value?The place value of a number can be defined as the position of the number is a digit.
Given the digits, we have to determine the numbers of digits in the ones that is 1/10 the value of the digit in the tens place.
⇒ 6044. 7
The ones digit is 4
The tens digit is 40
Take ratio = 4/ 40 = 1/ 10
⇒ 8
The ones digit is 8
The tens digit is 80
Take ratio = 8/ 80 = 1/ 10
⇒ 9,777.1
The ones digit is 7
The tens digit is 70
Take ratio = 7/ 70 = 1/ 10

6. The Edwards's Theater chain has studied its movie customers to determine how much money they spend on concessions. The study revealed that the spending distribution is approximately normally distributed with a mean of $4.11 and a standard deviation of $1.37. What percentage of customers will spend less than $3.00 on concessions? a. 2.09% b. 20.9% c. 81.0% d. 209.0%
The percentage of customers will spend less than $3.00 on concessions is which is option (d).
Z-scores can be placed on a normal distribution curve. Z-scores range from -3 standard deviations (leftmost part of normal distribution curve) to +3 standard deviations (rightmost part of normal distribution curve). To use the z-score, we need to know the mean μ and the population standard deviation σ. A Z-score is a way to compare results to a "normal" population. Test or poll results have thousands of possible outcomes and units. These results often seem meaningless. A sample basic Z-score formula is z = (x - μ) / σ ...(1)It is given that mean is $4.11 , standard deviation is $1.37 and value is $3.00
Putting above values in equation (1) , we get

4.30. An internet service provider has two connection lines for its customers. Eighty percent of
customers are connected through Line I, and twenty percent are connected through Line II.
Line I has a Gamma connection time with parameters a = 3 and λ = 2 min-¹. Line II has
a Uniform(a, b) connection time with parameters a = 20 sec and b = 50 sec. Compute the
probability that it takes a randomly selected customer more than 30 seconds to connect to
the internet.
Using the uniform distribution, there is a 0.6667 = 66.67% probability that it takes a randomly selected customer more than 30 seconds to connect to the internet.
What is the uniform probability distribution?It is a distribution with two bounds, given by a and b, in which each possible outcome is equally as likely.
The probability of finding a value above x is:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
For this problem, the connection time has parameters a = 20 sec and b = 50 sec, as stated in the problem.
The probability that it takes a randomly selected customer more than 30 seconds to connect to is P(X > 30).
Hence, applying the formula, with the bounds, we have that:
P(X > 30) = (50 - 30)/(50 - 20) = 2/3 = 0.6667.
The measure above is the desired probability.

Assuming that the line segments CE and FH are parallel, then:Angle W
Here we have Opposite Angles by Vertex, so
W = 14
According to the attached figure, the angle W is also corresponding, so in the triangle CEG one of the angles will be 14°
Angle Z
The sum of the interior angles of a triangle is 180°, so for triangle CEG:
Z + W + 78 = 180
Z + 14 + 78 = 180
Z = 88
Angle X
Z and 4X are complementary angles, then
Z + 4X = 180
88 + 4X = 180

Consider the following problem.
One number is 3 less than 6 times a second number.
Their sum is 46. Find the numbers
If × represents the second number, which equation is
correct for solving this problem?
Step-by-step explanation:
y is the second number. This means we can define it as the following equations where x is the second number:
y=6x-3
y+x=46
we have a system of equations, let's move all x to the right side
y=6x-3
y=46-x
this means that 6x-3=46-x
6x+x=46+3
7x=49
x=7
now that we know x we can calculate the y through one of the equations above:
y=39

The total mile Kaili ran during her training was 54.151 miles
Calculating total distanceFrom the question, we are to calculate the total miles Kaili ran during her training
From the given information,
" For the first five days of her training plan, she will need to walk 5.431 miles each day"

Also, from the information,
"For the next four days she will to increase her mileage and walk 6.749 per day"
That is,
She ran 4 × 6.749 miles
4 × 6.749 miles = 26.996 miles
Thus,
The total mile Kaili ran = 27.155 miles + 26.996 miles

Can you use absolute value when subtracting two negatives?
- 2 1/2 - (-1 2/3)
or does it only work when one number is negative?
Yes, it is possible to use absolute value when subtracting two negatives and as such it does not only work when one number is negative.
How to Interpret Absolute Values?
When adding two negative numbers, add the absolute value of the numbers and keep the negative sign.
For example -1 + -2 = - (||-1| + |-2||), which is -(1 + 2) or -3
The absolute value when subtracting two negatives is -2¹/₂ - (-1²/₃) is possible because when subtracting, we will change the subtraction to addition and change the sign of the number being taken away.
Thus, we can conclude that it is possible to use absolute value when subtracting two negatives.

There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.let x be the salary of individual with bachelor degree
Then the average salary of individual with Masters degree is:

the combined of two salaries is 130000:
x+(2x-40000)=130000
3x-40000=130000
