Answer:
x = -2/15.
Step-by-step explanation:
Finding the second derivative:
f'(x) = 15x^2 +4x - 3
f"(x) = 30x + 4
30x + 4 = 0 for a point of inflection
x = -4/30 = -2/15
So 30x + 4 is negative up to x = -2/15 and positive thereafter.
So the curve passes from concave downward to concave upward at x = -2/15.
Answer is 47.25

Answer:
2/36 or 1/18 simplified
Step-by-step explanation:
you have all the combinations listed which is good.
probability = number of successful events / number of total events
- look for the sums that are 11 and count them (there are 2 - 5,6 and 6,5).
- total the number of all events (36)
- so you then get the 2/36
there are
Yes. in math you will get to a point where you will have to use ratios to do rates they kind of the same thing.
