I UPPED THE POINTS AND WILL MARK BRAINLIEST TO THE BETTER ANSWERER Can someone who is good and actually likes algebra do these questions for me please I have asked countless times already. I have a zero for this assignment alreadyug I will mark you brainliest if you do this.

1. The following table shows the minimum wage rates for the United States during different years.
Year 1978 1979 1980 1990 1991 1996 1997 2007 2008 2009
Minimum hourly wage ($) 2.65 2.90 3.35 3.80 4.25 4.75 5.15 5.85 6.55 7.25

(a) Write the least squares regression equation that models the data. Let x equal time in years since 1900 and let y equal minimum hourly wage.
(b) Use the equation to estimate the minimum hourly wage of a US worker in 2025. Show your work.

3. Patty’s Parasols recorded the monthly rainfall and their umbrella sales for an entire year. The following table shows the inches of rainfall and the number of umbrellas the store sold each month. The relationship between the inches of rainfall and umbrella sales can be modeled using a linear function.
(Table in image below)
(a) Using technology, determine the correlation coefficient for the data to the nearest hundredth. Explain the steps you used.
(b) What does the correlation coefficient for the data indicate about the direction and strength of the linear association between the monthly rainfall and the number of umbrellas sold?
