Question

@Mathematics Day 1 2 3 4 5
Temperature (°F) 70 72 68 75 70

The temperature for 5 days is shown in the table. If on the 6th day the temperature is 83°, how will this change the overall mean temperature?

A)increase by 1°
B)increase by 2°
C)increase by 3°
D)increase by 4°

Answer 1

70 + 72 +68 +75 +70
= 355
355/5 = 71

70 + 72 +68 +75 +70 + 83
= 438

438/6 = 73

73 - 71 = 2

So the answer is B
