can you show the picture of the table? the questions says that there's a table but you didn't show it
Answer:
12 problems
Step-by-step explanation:
All problems were of equal value
Let x be the number of problems in the test
We apply a rule of three
x ------------------------------- 100%
(x-10) --------------------------- 17%
(x-10)*100%/(x) = 17%
(x-10)/(x) = 0.17
(x-10) = 0.17*x
0.83*x = 10
x = 12.05
x = 12 problems
Step-by-step explanation:
Its Undefined.
Reason
Slope (m) = y2 - y1/(x2-x1)
= 3-(-6)/(12-12)
=9/0
Undefined
You can clearly see this from the points. The x value has 2 different values for y... Which Makes the points not that of a function.
15% of $80 = 15*80/100 = $12
$80 - $12 = $68
