Step-by-step explanation:
Answer:
$175
Step-by-step explanation:
If after a 20% discount, it cost $140, the $140 is only 80% of the cost.
So divide 140 by 4 then multiply the answer by 5 to get it back to 100%
140/4=35
35x5=175
It is 11m+8
You just combine like terms
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
