Answer:
1. 125,000
3 17.5
4. 15
5. 17.5
Step-by-step explanation:
1. Create a unit rate. 20,000/8 = 2,500 straws per hour. This means in 50 hours multiply 2500*50 = 125,000.
3. Mean is the average and is found by adding all the date points and dividing by the number of them.
15 + 16 + 17 + 23 + 1 1+ 19 + 20 + 15 + 18 + 22 + 15 + 19 = 210
210 / 12 = 17.5
4. The mode is the number that occurs most often. Write the numbers in order and choose the one that happens the most.
11, 15, 15, 15, 16, 17, 18, 19, 19, 20, 22, 23
15 is the mode
5. The median is the number in the middle. If two numbers then take the average. The numbers in the middle when written in order are 17 and 18. So the 17+18 / 2= 17.5
now, for 2009, that's 9 years after 2000 so x = 9, and 2014, well clearly x = 14, so
