If it moves 29.9 meters a day, then we need to find the total amount of days:
1000 days + 100 days = 1100 days
Since it moves 29.9m per day, we can write:
29.9m x 1100 which equals 32 890m
So it moved 32 890m

Answer:
900 sample size
Step-by-step explanation:
To determine the sample size for a proportion, the margin of error formula is used to determine this:
Where p is the proportion, E is the margin of error, n is the sample size, q = 1 - p, is the z score.
Since the proportion is not known, the sample size needed to guarantee the confidence interval and error is at p = 0.5 and q = 1 - p = 1 - 0.5 = 0.5
E = 5% = 0.05, = 3. Hence:
Ritin has 21/5 lemonade and he distributed meaning he took away 13/4 liters of lemonade. Find a common denominator between 5 and 4. Since we know 5 times 4 is 20 the smallest common denominator so lets multiply 21/5 by 4 getting 84/20 and multiply 13/4 by 5 getting 65/20. Since both fractions have 20 as the denominator, subtract 84/20 by 65/20 and you get 19/20 liters of lemonade as your answer.
