Answer:
range = 6
IQR = 3.5
Step-by-step explanation:
range is greatest - least
18-12=6
IQR is the difference between quartile 3 and quartile 1
to find IQR you would want to put the numbers in order first
12, 12, 13, 13, 14, 15, 17, 18
then find the median of that set of numbers (you don't need to find the exact number just know where it is)
12, 12, 13, 13, || 14, 15, 17, 18
so the median is between 13 and 14 (where the || is)
then we find the median on both sides of the ||
find the median of 12, 12, 13, 13 and 14, 15, 17, 18
12, 12, || 13, 13 and 14, 15, || 17, 18
the medians are 12.5 and 16
subtract 12.5 from 16 to get 3.5
the IQR is 3.5

the graph of g(x) =x -5 is a translation of the graph of the parent function 5 units
Answer:
the answer is: 8(x)= 4 -5
Step-by-step explanation:
The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.
The given function is g(x)=x-5.
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Here, parent function is g(x) = x
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Shifted down: 5 units
The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.

I need help with this equation for math
Answer:
The answer would be B
Step-by-step explanation:
the y-intercept would be a postive 4 and because it's a negative slope, it would rule out all of them except B.
Answer:
y = -1/2x +4
Step-by-step explanation:
We have two points so we can find the slope
m = (y2-y1)/(x2-x1)
= ( 0-4)/(8-0)
= -4/8
= -1/2
We know the y intercept is 4
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = -1/2x +4

Three angles (degrees) in a kite are 105, 105 and 115. What is the missing angle total?
pls help i need it asap
Answer:
35 degrees
Step-by-step explanation:
we add all answers 105+105+115 and get 325 so we subtract 360 from 325 bc 360 is the maximum angle a quadrilateral can be.
Answer:
let missing no.be x
x+105+105+115=360(sum of angle of kite is 360)
x=360-325=35
therefore missing Angle is 35°

What would be the better option?
- Option A, broker charging 2% brokerage
- Option B, trade with an app that charges a flat brokerage
fee of $3 per trade.
Explain which offer is better in maths and words.
Answer:
Option B, trade with an app that charges a flat brokerage
fee of $3 per trade.
Step-by-step explanation:
1) In option A, the broker charges 2% brokerage. This means that 2% of the money invested goes to the broker. Since Angelika wants to invest $6000, the amount of money to be charged by the broker = 2% of $6000 = 0.02 * $6000 = $120
2) Option B uses an app that charges a flat brokerage of $3 per trade. This means that for any transaction, the money to be charged would be $3. Since Angelika wants to invest $6000, the amount of money to be charged by the broker = $3

Step-by-step explanation:
The value of the given expression is -2/5.
The given expression is [tex]\sqrt[3]{-\frac{8}{125} }[/tex].
How to solve cube roots?In mathematics, the definition of cube root is written as Cube root is the number that needs to be multiplied three times to get the original number. Now, let us look at the cube root formula, where y is the cube root of x. ∛x = y.
Now, [tex]\sqrt[3]{-\frac{8}{125} }[/tex] can be written as [tex]\sqrt[3]{(-\frac{2}{5})^{3} }[/tex].
