3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.
Open circle is a term used for numbers that are less than (<) or greater than (>). On the other hand, Closed circle is used for numbers that are less than or equal to (≤ ) and greater than or equal to (≥).
Here, we are given four inequalities, let us check them one by one-
A. h + 6 > -3h + 12
⇒ 4h > 6
or h > 3/2
Here, we see that there is no equality sign, this means that 3/2 won't be included and hence h + 6 > -3h + 12 would be an open circle inequality.
B. 7 ≥ d/3
⇒ d ≤ 21
Here, we can clearly see the equality sign which means that 21 will be included. Hence, 7 ≥ d/3 would not be graphed with an open circle.
C. 3(x - 2) < 18
x - 2 < 6
x < 8
Here, we see that there is no equality sign, this means that 8 won't be included and hence 3(x - 2) < 18 would be graphed with an open circle.
D. 2y ≤ 14
y ≤ 7
Here, we can clearly see the equality sign which means that 7 will be included. Hence, 2y ≤ 14 would not be graphed with an open circle.
Thus, 3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.

What is the difference between the value of the 4 in 25.48 and 12.64
Answers
The difference between the values of 4 is 0.36.
We need to understand the place value and face value of a digit in a number.
Place value of digit is decided by putting the number of zeroes equal to the number of digits after that digit.
And the face value of a number is the number itself.
Here the two numbers given is 25.48 and 12.64. And we have to find the difference in place value of 4 in the given number.
The value of 4 in 25.48 is 0.40.
The value of 4 in 12.64 is 0.04.

What do we mean by conversion factors?A conversion factor is an amount that is used to multiply or divide one set of units into another. When converting to an equal value, the appropriate conversion factor must be used. To convert inches to feet, for example, the suitable conversion value is 12 inches equal to 1 foot.To find how many minutes must the runner run:
1 mile = 1.6 kmSo, 8.1 miles = 1.6 kmMinutes required are:

Distance that she wants to ride this week = 55.5 miles
Distance she has already ridden so far = 19 miles
Now, we are told that she will ride 5 more days.
If m is the average number of miles she has to ride to meet her goal, then we can say that;
5m + 19 = 55.5
Making m the subject by, we have;
m = (55.5 - 19)/5

Answers
An advantage of a weighted moving average (WMA) is that recent actual results can be given more importance than what occurred a while ago is a "true" statement because "Weighted moving averages could be adjusted to emphasize more recent data in forecasting."
What is moving average?Moving averages are popular tools for measuring momentum among active traders. The formula used to calculate the average is the primary distinction between a simple moving average, a weighted moving average, and an exponential moving average.
Some key features regarding the weighted moving average are-
The SMA calculates the average price above a specific time period, whereas the WMA emphasizes current data.The exponential moving average (EMA) is also weighted to reflect the most recent prices, however the rate of decrease among one price and its previous price is not constant but exponential.Weighted moving averages give more weight to recent data points as they're more relevant than data points from the distant past. The total of the weightings should equal 1 (or 100%). The weightings are distributed equally in the case of the simple moving average.To know more about moving average, here

90 = 10(x + 7) solve for x

Answers
Answer:
x = 2
Step-by-step explanation:
Simplifying
90 = 10(x + 7)
Reorder the terms:
90 = 10(7 + x)
90 = (7 * 10 + x * 10)
90 = (70 + 10x)
Solving
90 = 70 + 10x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10x' to each side of the equation.
90 + -10x = 70 + 10x + -10x
Combine like terms: 10x + -10x = 0
90 + -10x = 70 + 0
90 + -10x = 70
Add '-90' to each side of the equation.
90 + -90 + -10x = 70 + -90
Combine like terms: 90 + -90 = 0
0 + -10x = 70 + -90
-10x = 70 + -90
Combine like terms: 70 + -90 = -20
-10x = -20
Divide each side by '-10'.

There is an upper outlier and lower outlier that is 86.875 and -26.875.
An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. In a sense, this definition leaves it up to the analyst (or a consensus process) to decide what will be considered abnormal. Before abnormal observations can be singled out, it is necessary to characterize normal observations.

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
(a)
(x₁, y₁ ) = (- 3, - 4 ) and (x₂, y₂ ) = (0, y )
[tex]\frac{y-(-4)}{0-(-3)}[/tex] = [tex]\frac{y+4}{0+3}[/tex] = [tex]\frac{y+4}{3}[/tex] , then
[tex]\frac{y+4}{3}[/tex] = 2 ( multiply both sides by 3 )
y + 4 = 6 ( subtract 4 from both sides )
y = 2
ordered pair is (0, 2 )
(b)
(x₁, y₁ ) = (- 2, 2 ) and (x₂, y₂ ) = (x, 5 )
[tex]\frac{5-2}{x-(-2)}[/tex] = [tex]\frac{3}{x+2}[/tex] , then
[tex]\frac{3}{x+2}[/tex] = [tex]\frac{3}{7}[/tex] ( cross- multiply )
3(x + 2) = 21 ( divide both sides by 3 )
x + 2 = 7 ( subtract 2 from both sides )
x = 5
ordered pair is (5, 5 )
(c)
(x₁, y₁ ) = (x, 5 ) and (x₂, y₂ ) = (1, - 5 )
[tex]\frac{-5-5}{1-x}[/tex] = [tex]\frac{-10}{1-x}[/tex] , then
[tex]\frac{-10}{1-x}[/tex] = [tex]\frac{-5}{2}[/tex] ( cross- multiply )
- 5(1 - x) = - 20 ( divide both sides by - 5 )
1 - x = 4 ( subtract 1 from both sides )
- x = 3 ( multiply both sides by - 1 )
x = - 3
ordered pair is (- 3, 5 )
(e)
(x₁, y₁ ) = (- 6, y ) and (x₂, y₂ ) = (8, 2 )
[tex]\frac{2-y}{8-(-6)}[/tex] = [tex]\frac{2-y}{8+6}[/tex] = [tex]\frac{2-y}{14}[/tex] , then
[tex]\frac{2-y}{14}[/tex] = - [tex]\frac{1}{7}[/tex] ( cross- multiply )
- 7(2 - y) = 14 ( divide both sides by - 7 )
2 - y = - 2 ( subtract 2 from both sides )
- y = - 4 ( multiply both sides by - 1 )
y = 4
ordered pair is (- 6, 4 )

Answer:
15. x = 4
17. AB = 9
Step-by-step explanation:
15.
Since B is in the middle of AC, AB + BC = AC
So,
x + 5 + 2x - 4 = 13
3x + 1 = 13
3x = 12
x = 4
17.
Since B is in the middle of AC, AB + BC = AC
So,
x + 16 + x + 17 = 19
2x + 33 = 19
2x = -14
x = -7
Going back to the question, it says to find the length of AB.
AB = x + 16 = -7 + 16 = 9
Two customers spent the same total amount of money at a resturant.
* The first customer bought 8 hot wings and left a $4 tip.
* The second customer bought 10 hot wings and left a $2.80 tip.
* Both customers paid the same amount per hot wing.
How much does one hot wing cost at this resturant in dollars and cents?
Answers
Considering the definition of an equation and the way to solve it, the cost of one hot wing is $0.6.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.
The solution of a equation means determining the value that satisfies it and the equality must be true.
To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.This caseBeing "x" the cost of one hot wing, and knowing that:
The first customer bought 8 hot wings and left a $4 tip. → First customer payment= 8x +4The second customer bought 10 hot wings and left a $2.80 tip. → Second customer payment= 10x + 2.80Both customers paid the same amount per hot wing.the equation in this case is:
First customer payment= Second customer payment
8x +4= 10x +2.80
Solving:
4 - 2.80= 10x - 8x
1.2= 2x
x= 1.2 ÷ 2
x=0.6
Finally, the cost of one hot wing is $0.6.
