(-2, 5) Minimum
Step-by-step explanation:
y-5=(1/3)(x + 2)²
y-5=(1/3)(x²+4x+4))
y-5=1/3x²+4/3x+4/3
y=1/3x²+4/3x+4/3+5
y=1/3x²+4/3x+4/3+15/3
y=1/3x²+4/3x+19/3
graph is attached
x= -b/2a
x= (-4/3)/2(1/3)
x= (-4/3)/(2/3)
x= (-4/3)*(3/2)
3's cancel
x= (-4/1)*(1/2)
x = -4/2
x = -2
plug -2 back into
y=1/3x²+4/3x+19/3
y=1/3*4+4/3*-2+19/3
y=4/3-8/3+19/3
y=15/3
y=5

Step-by-step explanation:
Toss; 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Total number of heads so far; 1, 1, 1, 1, 2, 3, 4, 4, 4, 5
Relative Frequency of heads so far;
= 1.0 = 100%
= 0.5 = 50%
= 0.33 = 33%
= 0.25 = 25%
= 0.4 = 40%
= 0.5 = 50%
= 0.57 = 57%
= 0.5 = 50%
= 0.44 = 44%
= 0.5 = 50%
Total number of tails so far; 0 1, 2, 3, 3, 3, 3, 4, 5, 5
Relative Frequency;
= 0 = 0%
= 0.5 = 50%
= 0.66 = 66%
= 0.75 = 75%
= 0.6 = 60%
= 0.5 = 50%
= 0.42 = 42%
= 0.5 = 50%
= 0.55 = 55%
= 0.5 = 50%
