Step-by-step explanation:
Data Set A: 14, 21, 24, 28, 28, 35
Data Set B: 18, 19, 21, 25, 29,32
Median:
Data Set A = 26
24 + 28 = 52
52/2 = 26
Data Set B = 23
21 + 25 = 46
46/2 = 23
Mean:
Data Set A = 25
14 + 21 + 24 + 28 + 28 + 35 = 150
150/6 = 25
Data Set B = 24
18 + 19 + 21 + 25 + 29 + 32 = 144
144/6 = 24
Answer:
The number of pennies are 91 pennies
Step-by-step explanation:
The given parameters are
When we split the pennies in twos the number left = 1
When the pennies are split in 3s the number left = 1
When the pennies are split in 5s the number left = 1
When the pennies are split in 7 the number left = 0
Therefore, 7 is a factor of the number
Given that when the pennies are split in 5s the number left = 1, the number ends with a 1
We have the products of 7 ending with 1 from Excel as 21 and 91, 161...
We check 91 given 21 is directly divisible by 3 as follows;
91/2 = 45 remainder 1
91/3 = 30 remainder 1
91/5 = 18 remainder 1
91/7 = 13 remainder 0
Therefore, the number of pennies are 91 pennies.
