Answer:

The circle cannot be formed.

Step-by-step explanation:

The polygons that are NOT formed when a cube is intersected by a plane would be : circle  

A cube has only six plane faces, it is impossible that a plane can intersect a cube and create a cross section with a curved face. So a circle cannot be formed.

A square is formed when a cube is intersected by a plane parallel to its base.

A rectangle is formed when a cube is intersected by a plane in two pairs of opposite faces.

A triangle is formed when a cube is intersected by a plane in three adjacent faces.

Answer:

The carnival is losing (on average) $0.15 on each play

Step-by-step explanation:

To find out how much the carnival wins or looses in each play one subtract the expected value (EV) from each play from the amount charged by the carnival for each play ($0.55). If the expected value is higher than what the carnival charges, the carnival is losing money.

Expected is the sum of the payouts of each bet multiplied by its likelihood:

EV= \frac{64*0.40+25*1.15+1*9.00}{90}\\EV= 0.70

Since the expected value is higher than $0.55, the carnival is losing money, on average, on each play:

0.55-0.7 = -0.15

The carnival is losing (on average) $0.15 on each play

Determine if the function f is an exponential function. If so, identify the base. If not, why not?
pishuonlain [190]

Answer:  D) The base is e^(-1)

We use the rule that x^(-k) = 1/(x^k). That allows us to say e^(-1) = 1/(e^1) = 1/e

The 1/e is the base of the exponential (1/e)^x

In general, the exponential b^x has base b.
