If a set of exam scores forms a symmetrical distribution, then the student mean scores is the median and the mode too.
<h3>What is a Symmetrical distribution?</h3>
A symmetrical distribution by definition is the situation which occurs when the values of variables appear at regular frequencies and is characterized by the mean, median, and mode all occuring at the same point in most cases.
Graphically, symmetrical distributions may appear as a normal distribution (i.e., bell curve).

Answer:
$4150
Step-by-step explanation:
Given data
Salary= $2500
Commission= 10%
Sales= $16500
Let us find the amount of the commission made
=10/100*16500
=0.1*16500
=$1650
Hence the total amount made for the month is
=commission + salary
=1650+2500
=$4150
1m is equal to 100cm, so the scale reduces the size of the actual object
The coordinated of the preimage would be :
x = x cos θ + y sin θ
y = x sin θ + y cos θ
where
x = -4
y = 7
θ = -90
hope this helps
