Devin is investigating the relationship between the temperature in degrees Fahrenheit and the number of gallons of lemonade sold at a lemonade stand at a lemonade stand on each day during a particular week. Her data is shown in the table

Using a regression calculator, what is a good line of best fit for the data

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

the answer is (-4,-4)

hope this ! : d

what i would say the best answer is a. 40.5
