Answer:
The mean absolute deviation of the data set is 2.4
Step-by-step explanation:
To determine the mean absolute deviation (MAD) of the data, we start by finding the mean of the data set.
The mean is obtained by finding the sum of the data values, and then dividing the sum by the number of data values.
Find the absolute value of the difference between each data value and the mean: |data value – mean|.
Find the sum of the absolute values of the differences.
Divide the sum of the absolute values of the differences by the number of data values.

A piecewise function is a function that behaves differently in different intervals.
Here the piecewise function is:
f(x) = $2 if x < 5
f(x) = x - $3 if x ≥ 5
We know that:
"Fun park charges an entry fee of $2 for any family with less than 5 members."
"The park charges $3 less than the number of family members for the entry of any family with 5 or more members."
If we define x as the number of members of a family, the function of the price will be:
f(x) = $2 if x < 5 (the cost is $2 if the family has less than members)
f(x) = x - $3 if x ≥ 5 (the cost if the family has 5 members or more)

Answer:
d
Step-by-step explanation:
The segment inside the triangle bisects the angle and divides the opposite sides into segments that are proportional to the other two sides, that is
= 
= 
( cross- multiply )
15x = 637.5 ( divide both sides by 15 )
x = 42.5 → d
Answer:
$15.50
Step-by-step explanation:
The total she spent was $28.50 ($18.00 purse and $10.50 wallet).
The amount she would have spent is $44 ($30+$14).
$44 - $28.50= $15.50 was saved.
