Call a household prosperous if its income exceeds $100,000. Call the household educated if the householder completed college. Se
melisa1 [442]

Answer:  0.317

Step-by-step explanation:

Let A be the event that the selected household is prosperous and B the event that it is educated.

Given : P(A)=0.138,   P(B)=0.261

P(A and B)=0.082

We know that for any events M and N ,

\text{P(M or N)=P(M)+P(N)-P(M or N)}

Thus , \text{P(A or B)=P(A)+P(B)-P(A or B)}

\text{P(A or B)}=0.138+0.261-0.082\\\\\Rightarrow\text{ P(A or B)}=0.317

Hence, the probability P(A or B) that the household selected is either prosperous or educated = 0.317

Determine the x intercepts of the piecewise function in the image that I sent.
Amanda [17]

To find the x intercept of the function, we would find g(x) = 0

To do this, we would set each expression in the piecewise function to zero and solve for x. We have

For

x/3 + 2 = 0

let us multiply both sides of the equation by 3. We have

x/3 * 3 + 2 * 3 = 0 * 3

x + 6 = 0

x = - 6

- 6 is less than - 1

- 6 < - 1

It satisfies the inequality. Thus, x = - 6 is in the domain

For

4x - 2 = 0

adding 2 to both sides of the equation, we have

4x - 2 + 2 = 0 + 2

4x = 2

Dividing both sides of the equation by 4, we have

4x/4 = 2/4

x = 1/2

x = 1/2 is less than 1. It is not in the domain of this equation. Thus, there is no x interscept at x = 1/2

Therefore, the x intercept of the piecewise function is (- 6, 0)

How do we multiply numbers
zavuch27 [327]

To multiply a number, simply take a number (Let's say 4) and another number (Let's say 3). If you multiply 4 by 3, you are simply taking the number 4, and adding it to itself 3 times (4 + 4 + 4).

I hope this makes sense, please tell me if you need some more information.

Hope this helps!
