Answer:
<av>={(-4)+(-7)+(-13)+(-5)+(-6)}/5

here you have to find average low temperature!
temperature by days is given, but to find average you have to add all the temperature recorderd first then divide it by total no. of days to get average of them!
average of any thing is determined by (sum of total observation)/(number of observation)
