Answer:
one
Step-by-step explanation:
3x-7=4+6+4x
3x=7+4+6+4x
3x=17+4x
3x-4x=17
-x=17
x=-17
The formula of a volume of a cone:
We have:

Answer: 1206 cm³
Answer:
It's a bit unclear with the table this way, but I count fifteen points, fifteen lines of the table, each a pair of numbers.
That's 15 degrees of freedom in the data. When modeling, each parameter in the model uses up one degree of freedom, so you'd use a smaller number of degrees of freedom when calculating t statistics, etc.
One would be 2pi - 5pi/18 = 31pi/18
another positive one is 31pi/18 + 36pi/18 = 67pi/18
and the negative angle is -5pi/18 - 36pi/18 = -41pi/18
The answer is b
