The average temperature on Monday, Tuesday, and Wednesday was 30C The Wednesday and Thursday are 31C. If the temperature on Thursday was 32C then what was the temperature on Monday?
Answer: 29
Explanation
The average temperature on Monday, Tuesday, and Wednesday= 30C
The temperature of Tuesday, Wednesday, and Thursday= 31C
Temperature of Thursday = 32C
formula:
Mean= Sum of no. observation/ No. of observation
Calculation:
The average temperature on Monday, Tuesday, and Wednesday= 30C
total= 30 x 3 = 90
The temperature of Tuesday, Wednesday, and Thursday= 31C
total= 31 x 3 = 93
Temperature of Thursday = 32C
(Tuesday + Wednesday + Thursday) - ( Monday + Tuesday + Wednesday) = 32
Thursday - Monday = 3C
Monday = 32 - 3= 29C
