Answer:

The answer is f(x) = 0.8(2^x)

Step-by-step explanation:

∵ f(x) = 0.8(2^x)

∵ x = -2 ⇒ ∴ f(-2) = 0.8(2^(-2)) = 0.2

∵ x = -1 ⇒ ∴ f(-1) = 0.8(2^(-1)) = 0.4

∵ x = 0 ⇒ ∴ f(0) = 0.8(2^(0)) = 0.8

∵ x = 1 ⇒ ∴ f(1) = 0.8(2^(1)) = 1.6

∵ x = 2 ⇒ ∴ f(2) = 0.8(2^(2)) = 3.2

∴ The answer is f(x) = 0.8(2^x) ⇒ The fourth answer

Answer:

The choice D is correct.

Step-by-step explanation:

We have given table.

We have to find the function for this table from the given choices.

The choice D is correct.

The function is :

f(x) = 0.8(2ˣ)

When x = -2 ,the value of function is:

f(-2) = 0.8(2⁻²) = 0.2

When x = -1 , the value of function is :

f(-1) = 0.8(2⁻¹) = 0.4

When x = 0, the value of function is :

f(0) = 0.8(2⁰) = 0.8

When x = 1 , the value of function is:

f(1) = 0.8(2¹) = 1.6

When x = 2, the value of function is:

f(2) = 0.8(2²) = 3.2

f(x) = 0.8(2ˣ) is  the function for this table

If A and B are independent events, P(A) = 0.25, and P(B) = 0.3, what is P(AB)?
Marrrta [24]

Answer:

P(A) = 0.25, P(B= 0.3

And if we want to find P(A \cap B) we can use this formula from the definition of independent events :

P(A \cap B) =P(A) *P(B) = 0.25*0.3= 0.075

And the best option would be:

P(A \cap B) =0.075

Step-by-step explanation:

For this case we have the following events A and B and we also have the probabilities for each one given:

P(A) = 0.25, P(B= 0.3

And if we want to find P(A \cap B) we can use this formula from the definition of independent events :

P(A \cap B) =P(A) *P(B) = 0.25*0.3= 0.075

And the best option would be:

P(A \cap B) =0.075
