Median is the middle number
60, 60, 65, 70, 70, 85, 90
70 is your median
mode is the number(s) that show up the most
60 and 70 is your mode, since they show up twice (one more than the others)
Range is largest number minus the smallest
90 - 60 = 30, 30 is your range
Mean is all the numbers added together divided by the number of numbers there are
60 + 90 + 65 + 70 + 70 + 85 + 60 = 500
500/7 = 71.42
Mean = 71.42
hope this helps
Answer:
B. 4 3/8
Step-by-step explanation:
7/8 X 5 = 4 3/8
8x+9-4x=25
4x+9=25
4x+9-9=25-9
4x=16
4x/4=16/4
X=4
1m= 1000mm
so 64mm*1m/1000mm=64/1000m
Answer:
A. She wrote 19 numbers
B. She wrote 12 numbers
C. She wrote 29 digits
Step-by-step explanation:
To find haw many numbers from x to y subtract x and y and then add 1
- Ex: There are 6 numbers from 1 to 6 because (6 - 1) + 1 = 6 (1, 2, 3, 4, 5, 6)
To find how many numbers between x and y subtract x and y then subtract 1
- Ex: There are 4 numbers between 1 and 6 because (6 - 1) - 1 = 4 (2, 3, 4, 5)
The numbers from 1 to 9 have one digit and from 10 to 99 have two digits
A.
∵ Mary wrote all the integers from 1 to 19
∵ (19 - 1) + 1 = 19
∴ She wrote 19 numbers
B.
∵ Rena wrote all the integers from 1 to 12
∵ (12 - 1) + 1 = 12
∴ She wrote 12 numbers
C.
∵ Mary wrote all the integers from 1 to 19
∵ From 1 to 9 the numbers have one digit
∵ There are 9 numbers from 1 to 9 because (9 - 1) + 1 = 9
∴ The number of digits from 1 to 9 = 9 × 1 = 9 digits
∵ There are 10 numbers from 10 to 19 because (19 - 10) + 1 = 10
∵ From 10 to 19 each number has 2 digits
∴ The number of digits from 10 to 19 = 10 × 2 = 20 digits
∴ The number of digits from 1 to 19 = 9 + 20 = 29 digits
∴ She wrote 29 digits
