#3 Which of the following is less than 527 m?
A. 0.000699 Mm = 0.000699 · 1,000,000 m = <u>699 m</u>
B. 914,879,710 nm = (914,879,710 : 1,000,000,000) m = <u>0.914879710 m</u>
C. 51,723 cm = (51,723 : 100) m = <u>517.23 m</u>
The best answer is C
#4 How many songs would you have if the average file size is 4,000 kb?
8 gb: 1,700 songs
16 gb: 6,000 songs
2 gb: 500 songs
160 gb: 30,000 songs
64 gb: 14,000 songs
1 Terabyte = 1024 gb: so im guessing 350,000 songs
This depends on the length of the song and the file format/type. A typical mp3 song of around 4 minutes averages 4 MB (4000 KB).
Answer: 12x^2+4
Step-by-step explanation:
Answer:
15.2%
Step-by-step explanation:
There are 12 marbles in total and there are 5 red marbles, so the probability of getting a red marble is 5/12. There are now 11 marbles and there are 4 blue marbles. So the probability of getting a blue marble is 4/11.
You multiply these 2 values together.
5/12 * 4/11 = 20/132 = 0.1515
This is about 15.2%
The Expected value of a draw from the given question is; A; 0.77
We are told the face cards are K, Q, J. This means that there are 3 face cards for each of the 4 suits.
Since you earn 10 points for each face card, it means that;
total possible gain = 10 × 3 × 4 = 120
In a deck of cards, there are a total of 52 cards.
This means that;
Number of cards that are not K, Q or J = 52 - (4 × 3) = 40
Since 2 points are lost for drawing any of this 40 cards, then;
Total possible loss = 40 × 2 = 80
Expected gain = 120 - 80
Expected gain = 40
Expected value of a draw = 40/52
Expected value of a draw = 0.77
