The MAD of the given data set is 3.3.
What is MAD?The average absolute distance between each data value and the mean of a data set is measured as the mean absolute deviation (MAD). MAD is a metric or statistic that, like standard deviation, evaluates the spread or variance in your data. We assess the absolute distance between each data point and the mean in order to compute MAD. After that, averaging such distances. The MAD equation is as follows:
[tex]\frac {1}{n} \sum \limits_{i=1}^n |x_i-m(X)|[/tex]
m(X) = average value of the data set
n = number of data values
x_i = data values in the set
Given a data set of yearly rainfall for a 9-year period in inches:
29, 24, 19, 21, 23, 27, 26, 29, 18
The Mean of the given data is 24. The following table will calculate the Absolute deviation.
Data Value Deviation from mean Absolute Value of Deviation
29 29-25 = 4 |4| = 4
24 24-25 = -1 |-1| = 1
19 19-24 = -5 |-5| = 5
21 21-24= -3 |-3| = 3
23 23-24= -1 |-1| = 1
27 27-24 = 3 |3| = 3
26 26-24 = 2 |2| = 2
29 29-25 = 4 |4| = 4
18 18-24 = -6 |-6| = 6
Total of Absolute Deviations: 24
For MAD = 24/9 = 3.222
Therefore, the MAD for this set of data in inches is 3.222≅ 3.3 inches.

Answer:
Step-by-step explanation:
Teresa is going with her family to watch
professional barrel racers. Her family
buys 6 tickets. They have a coupon for
$1.50 off each ticket. They pay $52.50
altogether for their tickets. Write an
equation that you could use to represent
the situation. What is the price of a ticket
before using the coupon?
Answer:
6 * (x - 1.50) = 52.50 ; 10.25
Step-by-step explanation:
Given that :
Number of tickets purchased = 6
Coupon off per ticket = 1.50
Total Amount paid for tickets = $52.50
Let x = initial price of ticket :
Number of tickets purchased * (Initial ticket price - coupon) = total amount paid
6 * (x - 1.50) = 52.50
6x - 9 = 52.50
6x = 52.50 + 9
6x = 61.50
x = 61.50 / 6
x = 10.25
Hence, initial price of ticket = $10.25

what is the answer to x + 5 = -6
Answer:
x=-11
Step-by-step explanation:
If you subtract the 5 on both sides, you get -11.
I should explain further. So if you subtract the 5 on the left side, it will cancel out. Subtracting the 5 on the right side will give you the equation, -6 - 5, which is equal to -11.

Two cars were at a gas station, a red car and a blue car. The red car filled up with 12 gallons of gas and was able to travel. The blue car filled up with 15 gallons of gas and was able to travel 330 miles. What was the gas mileage of each car? Which car got better gas mileage?
Answer:
Red Car Gas mileage:
= Distance travelled/ Gas used
= 300/12
= 25 mpg
Blue Car gas mileage:
= 330/15
= 22 mpg
The car with the better mileage is the one that goes further per gallon of gas which is the Red Car.

HELP MATH LAST ONEE!! :D MARKING BRAINLISEST!
Answer:
y = -11
Step-by-step explanation:
The slope-intercept form of an equation of a line:
y = mx + b
m - slope
b - y-intercept → (0, b)
We have the slope m = 0 and the point (0, -11) → b = -11.
Substitute:
y = 0x - 11 = -11
It's a horizontal line.
Answer:
Step-by-step explanation:
Slope-intercept form: [tex]y=mx+b[/tex] when [tex]b[/tex] is the y-intercept and [tex]m[/tex] is the slope
The slope is already given in the question: 0
The y-intercept is the value of y when x is equal to 0. We can see that the given point, (0,-11) also tells us this. When x is equal to 0, y is equal to -11. Therefore, the y-intercept of the line is -11.
Finally, we plug the slope and the y-intercept back into the original equation.
[tex]y=mx+b\\y=0x+(-11)\\y=0-11\\y=-11[/tex]
I hope this helps!

Answer:
See below
Step-by-step explanation:
Verify the expression:
((1-tan^2(x))/(sec^2(x))=cos(2x)
-----------------------
(1-tan^2(x))/(sec^2(x) =(1-tan^2(x))/(1/cos^2(x) =(1-tan^2(x))*cos^2(x) =cos^2(x) - sin^2(x) = cos^2(x) - (1 - cos^2(x)) =2cos^2(x) - 1 =cos(2x)Done

You purchase a remote-controlled drone for d dollars. Your friend purchases a drone that costs $35 more than your drone. Your brother purchases a drone that costs three times as much as your friend's drone. Write and simplify an expression that represents the cost (in dollars) of your brother's drone.
Answer:
[tex]Brother = 105 + 3d[/tex]
Step-by-step explanation:
Given
[tex]Drone = d[/tex]
Friend = $35 more expensive than yours.
Brother = 3 * as much as your friend
Required
Write an expression for the cost of your brother's drone
I'll solve by analysing the question one sentence after the other
You:
[tex]Drone = d[/tex]
Your friend:
Friend = $35 more expensive than yours.
This means
[tex]Friend = 35 + You[/tex]
Substitute d for You
[tex]Friend = 35 + d[/tex]
Your brother:
Brother = 3 * as much as your friend
This means:
[tex]Brother = 3 * Friend[/tex]
Substitute 35 + d for Friend
[tex]Brother = 3 * (35 + d)[/tex]
Open bracket
[tex]Brother = 3 * 35 + 3*d[/tex]
[tex]Brother = 105 + 3d[/tex]
