answer:To solve this problem, we need to determine the value of x, which represents the number of slips with a 2 on them. We know that the expected value of the number shown on a slip randomly drawn from the bag is 3.25. The total number of slips in the bag is 12. Let's set up the equation for the expected value: (9 * X + (12 - 9) * 7) / 12 = 3.25 (9 * X + 3 * 7) / 12 = 3.25 (9 * X + 21) / 12 = 3.25 9 * X + 21 = 39 9 * X = 39 - 21 9 * X = 18 To solve for x, we divide both sides of the equation by 9: X = 18 / 9 X = 2 The value of x is 2. The answer is: 2

answer:In his new job, Jame makes 20 per hour and works 40 hours a week, so his weekly income in his new job is 20 * 40 = 800. In his old job, he made x an hour for 25 hours per week, so his weekly income in his old job is x * 25. To find out how much more money he makes per year in his new job than the old job, we need to calculate the difference in their yearly incomes. Since there are 52 weeks in a year, his yearly income in his new job is 800 * 52 = 41,600. His yearly income in his old job is x * 25 * 52. The difference in their yearly incomes is 41,600 - (x * 25 * 52). We are given that the difference in their yearly incomes is 20,800, so we can write: 41,600 - (x * 25 * 52) = 20,800. Simplifying the left side, we get: 41,600 - 1300x = 20,800. Subtracting 41,600 from both sides, we get: -1300x = -20,800. Dividing both sides by -1300, we get: x = 16. The value of x is 16. 16 The answer is: 16

answer:If there are 4 brown stripes, and there are three times as many gold stripes, then there are 4 * 3 = 12 gold stripes. If there are five times as many blue stripes as gold stripes, then there are 12 * 5 = 60 blue stripes. So Vaishali's Saree has 60 blue stripes. 60 The answer is: 60

answer:20% of 200 is 20/100 * 200 = 40 So, Susie adds 40 to her piggy bank The total amount of money in her piggy bank will be 200 + 40 = 240 240 The answer is: 240
