Identify the variation as direct, inverse, joint or combined.
if the area of a rectangle stays constant, the relationship between the base and the height.
direct
inverse
joint
combined

Answer with explanation:

→Area of Rectangle =Base(B) × Height(H)

 Let area of rectangle which is a constant Value =A

⇒ A = B × H

Means , B × H is a Constant value.

So, if Base increases then Height decreases keeping Area Constant or if Base Decreases then Height will increase Keeping Area constant in both the cases.

So, Base and Height are Inversely Proportional to each other.

Option B→ Inverse

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
