A. Coefficient of Variation
If you set up a proportion, this will make sense.
Now, Cross Multiply
6x = 12.5
x = 25/12
Answer:
both plumbers charge $120 for 3 hours of work
Step-by-step explanation:
1) x=3 and x stands for hours.
2) 120=y and y stands for money charged
so the points (3, 120) show that the plumbers both charge 120 for 3 hrs.
Step-by-step explanation:
If x − 2 is a factor of p(x), then p(2) will equal 0.
p(x) = x⁴ − 3x² + 2x − 8
p(2) = 2⁴ − 3(2)² + 2(2) − 8
p(2) = 16 − 12 + 4 − 8
p(2) = 0
So x − 2 is indeed a factor of p(x).
