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:
- 63 in the class
- (C+B)P' = 25
- (C+B+P)' = 18
Step-by-step explanation:
The number of students in the class is the total of all numbers on the diagram:
9 +5 +11 +6 +3 +4 +7 +18 = 63 . . . students in the 2015 senior class
__
Students taking Chem or Biology, but not Physics are those in the colored area, excluding those in the green:
9 +5 +11 = 25 science students not taking Physics
__
Students not taking science are those outside the colored areas:
18 students are not taking science
Answer:
B. 3/2
Step-by-step explanation:
If f(x) and are inverse, that means that if we switch the x and y for f(x) and solve for y, we will get the inverse function.
Knowing that f(x) = 2x + 5, let's write this as y = 2x + 5 and switch the x and y:
x = 2y + 5
Now, solve for y:
x = 2y + 5
x - 5 = 2y
y = (x - 5)/2
That's the function:
Plug in 8 for x:
The answer is thus B.

Answer:
The density is 0,8687 grs/cm³
Step-by-step explanation:
To solve this problem you have to use the density formula
Density = Mass/ Volume ⇒ Density = 139 kg/ 160 L.
Density is commonly has the units grs/cm³, so
Density = 139000 grs/ 160000 cm³ ⇒ Density = 0,8687 grs/cm³
