Answer: A. 0.2
Step-by-step explanation:
Probability for any event =
Three flavors of juice are offered at a school cafeteria.
The given table:
Orange Grape Cherry
51 30 69
Total juices = 51+30+69 =150
Now, the probability that a student who bought juice chosen at random purchased the grape flavor=
Hence, the correct option is A.
Take the derivitive
f'(x)=3x^2+12x
find where it equals zero
it equal zero at x=0 and x=-4
find the y values
f(0)=-36
f(-4)=-4
the critical points are (0,-36) and (-4,-4)
make sign chart
evalutat f'(x) at x=-5 and x=-1 and x=1, and see their signs
f'(-5)=(+)
f'(-1)=(-)
f'(1)=(+)
see below attachment
max is where sign changes from (+) to (-)
min is where sign changes from (-) to (+)
so
max at (-4,-4)
min at (0,-36)
none of the options are correct, do you have te right problem?
