Steps To Solve:
4x - 32 = -8
~Add 32 to both sides
4x - 32 + 32 = -8 + 32
~Simplify
4x = 24
~Divide 4 to both sides
4x/4 = 24/4
~Simplify
x = 6
-------------------------------------------------
Answer:
x = 6

In this case, we can use the z statistic to find for the proportion
of students who failed the exam. The formula for z score is given as:
t = (x – u) / s
where,
x = the sample score = 60
u = sample score mean = 82
s = standard deviation = 11
Substituting all given values into the equation:
t = (60 – 82) / 11
t = - 2
Based from the standard proportion distribution tables for
z, this corresponds to:
P = 0.0228
This means that 2.28% of the students failed the exam or
equivalent to:
failed students = (0.0228) * 85 = 1.938
<span>approximately 2 students failed the exam</span>
It depends on how fast it was thrown/kicked but the average is around 9/10
