Amanda rolls a prime number on a die. she rolls again and gets a 3. this situation describes a compound event. it's true right?

Yes, It is a compound event.                

Step-by-step explanation:

Given : Amanda rolls a prime number on a die. She rolls again and gets a 3.

To find : This situation describes a compound event or not?

Solution :

Compound event is defined as an event that has more than one possible outcomes.

Favorable outcomes of getting a prime on a 6-sided die is 2,3,5 i.e. 3 possible outcomes.

Total outcome = 6

When she rolls again she get a 3.

i.e. Probability of getting 3 is

As in a compound event, an experiment gives more than one possible outcomes. These outcomes may have different probabilities but they are all equally possible.

Therefore, The situation given above is a compound event.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
