-------------------------------------------------------------------------------------------------------
Evaluating the expression for the given values of x:
<u></u>
Evaluated set of values: -5, -3, -1, 1, 3, 5
To find the Mean Absolute Deviation (MAD):
- Calculate the mean (by summing the data values and dividing by the number of values)
- Subtract the mean from each value in the data set and take the absolute value of each result.
- Sum the absolute values from step 2.
- Divide by the number of values.
<u></u>
Absolute values:
Sum of absolute values = 18
Answer:
20 tshirts and 150 keychains
Step-by-step explanation:
let tshirts be 10x and keychains be 2y
now make a Quadratic equation,
10x+2y=500
=let x = 20
=(10×20)+2y=500
=200+2y=500
=2y=300
y=300/2 = 150
therefore 20 tshirts and 150 keychains sumsup their goal of 500 dollars
$34*.15= 5.1 off
34-5.1= $28.99
