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.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

answer: the first graph
