Answers
Answer:
We have two graphs actual and forecast, In the graph x−axis represents days and y−axis represents the temperature
Scale :
On x−axis 4 cm =1 day
On y−axis 2 cm =5
0
C
To find the temperature at particular day:
Trace the vertical line parallel to y−axis passing from the point on x−axis, find the point where this vertical line intersects the graph.
Now from that point trace a horizontal line parallel to x−axis, this line intersects the y−axis at required point.
To find the day at particular temperature:
Trace the horizontal line parallel to x−axis passing from the temperature point on y−axis, find the point where this horizontal line intersects the graph.
Now from that point trace a vertical line parallel to y−axis, this line intersects the x−axis at required point.
Now,
a) Forecast temperature and actual temperature are same where the graphs of both intersects which is Tuesday, Friday and Sunday
b) Follow step 1 to find temperature for graph forecast on days of week,
