What is the appropriate measure of variability for the data shown, and what is its value?
A. The range is the best measure of variability and equals 14.
B. The IQR is the best measure of variability and equals 4.
C. The mean is the best measure of variability and equals 11.
D. The median is the best measure of variability and equals 11.
The most appropriate measure of variability for this data set is the IQR,
Option B is the correct answer.
What is the interquartile range?An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.
W can find the values of the upper and lower quartile and median from a box plot.
The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.
The formula used is Upper quartile - Lower quartile.
We have,
To determine the appropriate measure of variability for the given data, let's first calculate some descriptive statistics:
Mean: (5 + 8 + 10 + 12 + 12 + 19) / 6 = 11
Median: the middle value is 11, since there are an even number of values
Range: the difference between the maximum value (19) and the minimum value (5) is 14
Interquartile range (IQR): Q3 (the third quartile) is the median of the upper half of the data, which is (12, 12, 19), and Q1 (the first quartile) is the median of the lower half of the data, which is (5, 8, 10). Thus, Q3 = 12 and Q1 = 8, and the IQR is 12 - 8 = 4.
Now, we need to determine which measure of variability is most appropriate for this data set.
Option A suggests using the range, which is the difference between the maximum and minimum values.
The range is affected by outliers and extreme values, and in this data set, the value of 19 is significantly larger than the other values, which might make the range an unreliable measure of variability.
Option B suggests using the IQR, which is a measure of the spread of the middle 50% of the data.
The IQR is less affected by extreme values than the range and is often preferred when there are outliers or skewed distributions.
Option C suggests using the mean, which is a measure of central tendency, not variability.
Option D suggests using the median, which is also a measure of central tendency, not variability.
Therefore,
The most appropriate measure of variability for this data set is the IQR,

2x+4 is an alternate angle to the angle opposite on the top left to 5x+8
Which means (2x+4)+(5x+8)=180
So add both together to get
7x+12= 180
Then subtract 12 from 180
7x=168
then divide 168 by 7 to get

Jonathan needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 3 hours and charged him $141 for parts. The total was $336. Write and solve an equation which can be used to determine x, the cost of the labor per hour.
================================================
Work Shown:
x = cost of labor per hour
3x = cost of the 3 hours of labor
3x+141 = cost of labor plus parts = total cost
3x+141 = 336
3x = 336-141
3x = 195
x = 195/3
x = 65
The hourly wage is $65 per hour for labor.
------------
Check:
1 hour = 65 dollars in labor costs
3 hours = 3*65 = 195 dollars in labor costs
195+141 = 336 dollars total
The answer is confirmed.

Step-by-step explanation:
4. P=2*(5+7)=2*12=24 ft
S= 5*7=35 ft
5. P=2*(3+8)=2*11=22 cm
S= 3*8=24 cm
6. P=2*10+12=20+12=32 m
S= 12*8/2=48 m
7. P=12+13+5=30 in.
S= 12*5/2=30 in.
In 2020, Forest A had an area of about 4000 acres and Forest B had an area of about 3600 acres. Researchers expect deforestation to cause the area of Forest A to decrease at a rate of 105 acres per decade and the area of Forest B to decrease at a rate of 30 acres per decade. In what year do they expect the areas of the forests to be the same?
Answer:
In about 2073, 3440 acres
Step-by-step explanation:
Determine the equation for each forest. Forest A: y=-105x+4000 Forest B: y=-30x+3600There are a number of ways to solve a system of equations, but for this we are first going to solve for x when -105x+4000=-30x+3600. In this case, x=5 1/3.Then, we are going to plug 5 1/3 in as x into one of our equations. To double check you have this right, you may do both. If our equation is y=-30(5 1/3)+3600, then y=3440.Add 5 1/3 decades or about 53 years to 2020.Therefore, they expect the area of the forests to be the same in about 2073. At this time, both will have an area of about 3440 acres.
In 2073 the areas of the forests to be the same.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Forest A had an area of about 4000 acres and Forest B had an area of about 3600 acres.
If Forest A to decrease at a rate of 105 acres per decade and the area of Forest B to decrease at a rate of 30 acres per decade.
let the number of decades occur be x
So, the equation is
4000 - 105x= 3600 - 30x
400 = 75 x
x= 5.33
x= 53.3 years
Hence, In 2073 the areas of the forests to be the same.

Triangle XYZ has vertices X: (0,2) Y: (3,8), and Z: (6,2). Show that the triangle is isosceles by determining the length of each side.
Please help!!!!
Answer:
given below
Step-by-step explanation:
formula used= [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]
XY= [tex]\sqrt{(3-0)^2+(8-2)^2}[/tex] = [tex]\sqrt{9+36} =\sqrt{45}[/tex] (here x1=0, x2=3, y1=2, y2=8)
YZ= [tex]\sqrt{(6-3)^2+(2-8)^2}[/tex] = [tex]\sqrt{9+36} = \sqrt{45}[/tex]
ZX= [tex]\sqrt{(6-0)^2+(2-2)^2}[/tex] = [tex]\sqrt{36+0} = \sqrt{36}[/tex]
as you can see side XY=YZ=45
so triangle XYZ is an isosceles triangle

Joelle can read 3 pages in 4 minutes, 4.5 pages in 6 minutes, and 6 pages in 8 minutes. Paxton can read 3 times as fast as Joelle. Which is the equation for the number of pages y that Paxton can read in x minutes?
A. y = 9/4x
B. y = 6/5x
C. y = 3/4x
D. y = 1/4x
Please show work
Answer:
C. y = 3/4x
Step-by-step explanation:
3 pages = 4 min
4.5 pages = 6 min
Paxton = Joelle×3
3/4 = 0.75 (Joelle reads 0.75 pages in 1 min)
Paxton = 0.75×3
C. y = 3/4x
for example if y=3 and x=4 than
3 = 3/4×4 3 = 0.75×4 (which equals to 3)

P.S: evaluate this function: f(x) = 3x^2+5x+6
Explanation:
This is unable to be evaluated due to the function not being stated. X has to be a number for us to be able to solve the equation and for It to be evaluated. 3x to the second power is gonna stay that since there isn't another power integer on 5x and 6 is staying like that since there is nothing for it to be added or subtracted to.
So the answer is simply:
3x^2+5x+6
