since the range on the horizontal axis has a range of 0 to 3, there is no way to know how many students collected an exact number of bottles,
so the answer would be the number of students who collected exactly 2 bottles
What is the complete question, I cannot work out the answer without there being a real problem, but I'll do my best,
If you are trying to do 120 - 94 then the answer will be a simple 26.
Thai is all I can do without specific information, im sorry.
Allison didn't drive at constant rate.
Step-by-step explanation:
We need to identify if time and distance have proportional relationship
A relationship is proportional if y/x = k
If x = time and y = distance and y/x is equal to constant then they have proportional relationship.
if x= 1, y=65 then k is:
y/x = 65/1 = 65
if x=2, y =120 then k is:
y/x = 120/2 = 60
if x=3,y=195 then k is:
y/x = 195/3 = 65
if x=4,y=220 then k is:
y/x = 220/4 = 55
if x=5,y=300 then k is:
y/x = 300/5 = 60
Since, y/x ≠ k i.e the ratio of y and x doesn't equal to the constant rate, so time and distance doesn't have proportional relationship.
So, Allison didn't drive at constant rate.

Answer:
(B) π/12 + π/6 k
Step-by-step explanation:
Points of inflection are where f"(x) = 0 and changes signs.
f(x) = cos²(3x)
f(x) = (cos(3x))²
f'(x) = 2 (cos(3x))¹ × -sin(3x) × 3
f'(x) = -6 sin(3x) cos(3x)
Using double angle formula:
f'(x) = -3 sin(6x)
f"(x) = -3 cos(6x) × 6
f"(x) = -18 cos(6x)
0 = -18 cos(6x)
0 = cos(6x)
6x = π/2 + 2πk or 6x = 3π/2 + 2πk
We can simplify this to:
6x = π/2 + πk
x = π/12 + π/6 k
