From total of 10000 programs only one is winning. The probability that you will get the winning number can be calculated as the ratio between the numbers of desired events and the total numbers of events. There is only one winning number , so the ratio is : 1/10000. If you purchase two programs the probability is the sum of the two probabilities: 1/10000+1/10000=2/10000.
Answer:
multiply by 25 also.
Step-by-step explanation:
If the scores are multiplied by 25, that means that the mean will also multiply by 25. Since the mean and the scores all increased by 25 times, the standard deviation will increase by 25 times.
If instead, you added 25 (or any other number) to each score, then the standard deviation would not change. The mean and each score will increase by 25, bu the difference between them will not change.
Area of a square = Length ^2
480 = (x+4)^2
√480 = x + 4
21.9 = x + 4
x = 17.9
Answer:
x=-9
Step-by-step explanation:
You first multiple 2 and 25 and 2 and 2x. Then the next line should be -9-3x>50+4x+4. After that you add 50 and
