HELP Please! 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

Mark Brainlies please!

y=0.126x-7.124 2025, x=125

y= (0.126)•125-7.124

y= 15.75 - 7.124

y= 8.626

y=$8.63

Step-by-step explanation:

Enter STAT on TI 83 or 84 graphing calculator. GO to 1 : Edit push enter. L1 enter all the years and L2 enter all minimum wages. Then push STAT AND MOVE RIGHT TO CALC ON TOP OK. SCROLL DOWN TO 4: LinReg ( ax+b) push enter. Push enter till it calculates. Then look at a=.1258733205 and round to the nearest thousandths which gives you 0.126 ok. This is the least square regression. y=0.126x-? . Ok then take the last wage which is 7.25 and subtract 0.126. Which gives you 7.124. y=0.126x-7.124. Then you need to figure out time time from 1900 to 2025. Take 2025 subtract from 1900 and gives you x= 125 years past 1900. Then take y= (0.126)•125-7.124

y= 15.75 - 7.124

y=8.626 round to the nearest hundredth y=$8.63. Hope this helps. Y’all have a great weekend.

answer: e 9, 5.75

step-by-step explanation:

step 1

find the variation ab in the x coordinate

delta x=(x2-x1)=10-> 8 units

find the variation ab  in the y coordinate 

delta y=(y2-y1)=6-> 2 units

step 2

find the coordinates point c

  x coordinate 

cx=ax+delta x*2/> cx=2+8*(2/> cx=3

  y coordinate 

cy=ay+delta y*2/> cy=4+2*(2/> cy=4.25

the coordinates of point c are (3,4.25)

step 3

find the coordinates point d

  x  coordinate 

dx=ax+delta x*4/> dx=2+8*(4/> dx=4

  y  coordinate 

dy=ay+delta y*4/> dy=4+2*(4/> dy=4.5

the coordinates of point d are (4, 4.5)

step 4

find the coordinates point e

  x  coordinate 

ex=ax+delta x*4/> ex=2+8*(6/> ex=5

  y  coordinate 

ey=ay+delta y*4/> ey=4+2*(6/> ey=4.75

the coordinates of point e are (5, 4.75)

step 5

find the coordinates point f

  x  coordinate 

fx=ax+delta x*4/> fx=2+8*(8/> fx=6

  y  coordinate 

fy=ay+delta y*4/> fy=4+2*(8/> fy=5

the coordinates of point f are (6,5)

step 6

find the coordinates point g

  x  coordinate 

gx=ax+delta x*4/> gx=2+8*(10/> gx=7

  y  coordinate 

gy=ay+delta y*4/> gy=4+2*(10/> gy=5.25

the coordinates of point g are (7,5.25)

step 7

find the coordinates point h

  x  coordinate 

hx=ax+delta x*4/> hx=2+8*(12/> hx=8

  y  coordinate 

hy=ay+delta y*4/> hy=4+2*(12/> hy=5.5

the coordinates of point h are (8,5.5)

step 8

find the coordinates point i

  x  coordinate 

ix=ax+delta x*4/> ix=2+8*(14/> ix=9

  y  coordinate 

iy=ay+delta y*4/> iy=4+2*(14/> iy=5.75

the coordinates of point i are (9,5.75)
