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>
The answer is
b. acute triangle
I think 6 is 36/100 I'm not real sure if that's the answer your looking for but if you divide it that's what you get
Total= Car Cost + (Car Cost * Tax %)
Total= $16,800 + ($16,800 * 6.25%)
convert % to decimal form; divide % by 100
Total= $16,800 + ($16,800 * 0.0625)
multiply inside parentheses
Total= $16,800 + $1,050
Total= $17,850
ANSWER: The total cost for the used car with tax is $17,850.
Hopd this helps! :)
