Answer: Our required probability is 
Step-by-step explanation:
Since we have given that
Number of cards in a deck = 52
Number of nines = 4
Number of hearts = 13
It is the case of replacement.
Probability of drawing a nine the first time and a hear the second time is given by
Hence, our required probability is

Answer:
Step-by-step explanation: First, you need to write all your data down from least to greatest. Next, count up all the numbers to see how many students. Then you want to find the mean which is average (add then divide). Median is the middle so you will x each number out till you get to the middle, and if the middle is 2 numbers, you find the average of them to find the median. Mode means most often. Range is highest minus lowest. And you can do the next 2.
Multiply the 3 times 4. Then do the same on the top.
I'm guessing this is a question about interest rates? If you have $20 that increases by 4% in one year, you need to multiply 20 by 1.04. This gets you $20.8.
If you are talking about compound interest, we will take this number and multiply it again by 1.04 for the second year. 20.8 x 1.04 = $21.632.
If it is instead simple interest, we will simply add another .8 dollars for each year, instead of getting 4% interest compounded every year onto the new value. This gets you $21.6.
