Question 1180630: The table below provides the average monthly temperature in London, England over the course of a year
Months Temperature (in degree)
1 January 7 degree
2 February 7.5 degree
3 March 9 degree
4 April 11 degree
5 May 14 degree
6 June 17 degree
7 July 19.5 degree
8 August 19 degree
9 September 16.5 degree
10 October 13 degree
11 November 9.5 degree
12 December 7 degree
a. Determine the equation of a sinusoidal regression function that best models the data. Express the values of a, b, c, and d to the nearest hundredth.
b. Use the sinusoidal regression equation above to predict the average temperature, to the nearest hundredth, in London next February.
c. Most tourists visit London during months when the average temperature is 13 °C and higher. Determine the month of the year when the temperature first reaches 13 °C.

You can put this solution on YOUR website! .
Go to this web-site
https://stats.blue/Stats_Suite/sinusoidal_regression_calculator.html
Find there free of charge online calculator for sinusoidal regression.
Use it to make at least part of the job on your own - I mean that part, which you can do using this calculator.
I am open to accept your "THANKS" for my instructions.
