There's a formula for that.

... P(A∪B) = P(A) + P(B) - P(A∩B)

Filling in the given values, we have

... P(A∪B) = 2/3 + 4/5 - 3/5 = 10/15 + 12/15 - 9/15

... P(A∪B) = 13/15 . . . . . . . . matches selection B

Graph the function, identify if it represents exponential growth or decay, and identify domain and range. See picture
Brrunno [24]

Answer:

a. Decay

b. 0.5

c. 4

Explanation:

If we have a function of the form

y=ab^x

then

a = intital amount

b = growth / decay rate factor

x = time interval

If b > 1; then the equation is modelling growth. If b < 0, then the equation is modelling decay.

Now in our case, we have

y=4(\frac{1}{2})^x

Here we see that

inital amount = a = 4

b = 1/ 2 < 0, meaning the function is modeling decay

decay factor = b = 1/2

Therefore, the answers are

a. Decay

b. 0.5

c. 4
