Phil has 50 nickels and dimes worth $4.15. How many of each coin does he have?
Answers
several students in Ashton 's class were randomly selected and asked how many text messages they sent yesterday. Their answers were 1 ,0 ,10 , 7 , 13, 2 , 9 ,15 ,0 , 3 .find the mean and the median for this data .
Answers
Mean is 6 because once you add up all the numbers it will be 60, and dividing that number by how many you have will give you 6
Median is 5 because once you place the numbers in order, 0, 0, 1, 2, 3, 7, 9, 10, 13, 15 the middle number in the set is between 3 and 7 and once you find the mean of the two you get 5
Mean: 6 ADD up all the numbers and then divide by 10. SO 60÷10=6. Median: 5 Put them in order and find the middle number. In this case 3 and 7 are in the middle. SO add them up and divide by 2. 3 + 7 =10.
