Answer:
Please find attached the required graph for the temperature time relationship
Step-by-step explanation:
The parameters given are arranged in a tabular form as follows;
At
Time Temperature
6 a. m. 56° F
7 a. m. 59° F
8 a. m. 62° F
9 a. m. 66° F
10 a. m. 70° F
11 a. m. 74° F
12 p. m. 74°F
1 p. m. 74°F
2 p. m. 74°F
3 p. m. 74°F
4 p. m. 74°F
5 p. m. 74°F
6 p. m. 74°F
7 p. m. 71°F
8 p. m. 68°F
9 p. m. 65°F
10 p. m. 62°F
11 p. m. 61.5°F
12 a. m. 61°F
With the above table as the data points, the graph can be drawn
From Excel, The Mean temperature is approximately 68.1°F
The standard deviation is 6.079 °F
0.40
4/10=0.40
7.9
area of circle equals π× 5 = 15.7
area of half of the circle equals 15.7÷2
=7.85
now round it of and it's 7.9
I hope this helps!
