Daily temperature

The average of daily temperature measurements in one week every day at the same hour was -2.8 °C. We measured all temperatures on different days are different. The highest daily maximum temperature was 2.4 °C, the lowest -6 °C. Determine the options that We can measure temperature in the remaining five days.

Correct answer:

a =  -3.4 °C
b =  -3.3 °C
c =  -3.2 °C
d =  -3.1 °C
f =  -3 °C

Step-by-step explanation:

6<=x<=2.4 (6+2.4+a+b+c+d+e)/7=2.8 s=a+b+c+d+e s=7 (2.8)+62.4=16 p=s/5=(16)/5=165=3.2 a=p0.2=(3.2)0.2=3.4°C
f=d+0.1=(3.1)+0.1=3 k=(6+a+b+c+d+f+2.4)/7=(6+(3.4)+(3.3)+(3.2)+(3.1)+(3)+2.4)/7=145=2.8 f=d+0.1=(3.1)+0.1=3°C
