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)+6−2.4=−16 p=s/5=(−16)/5=−516​=−3.2 a=p−0.2=5−16​−0.2=−3.4°C
b=a+0.1=5−17​+0.1=−3.3°C
c=b+0.1=10−33​+0.1=−3.2°C
d=c+0.1=5−16​+0.1=−3.1°C
f=d+0.1=10−31​+0.1=−3 k=(−6+a+b+c+d+f+2.4)/7=(−6+5−17​+10−33​+5−16​+10−31​+f+2.4)/7=(−6+(−3.4)+(−3.3)+(−3.2)+(−3.1)+(−3)+2.4)/7=−514​=−2.8 f=d+0.1=10−31​+0.1=−3°C
