3x+3y=10<br> -9x-9y=-30<br> please help
tiny-mole [99]

Answer:

             Infinitely many solutions.

Explanation:

              In this case we gonna use ELIMINATION BY ADDITION method.For that first we are gonna eliminate the terms containing ( X ).

 Equation no 1:

                            3x + 3y = 10

 Equation no 2:

                           -9x - 9y = -30

  Now multiply equation no 1 with (3 )

                           3(3x + 3y) = 3(10)

                              9x + 9y = 30             ( equation no 1 )

   Now ADD both the equations

                            9x + 9y = 30

                           <u> -9x - 9y  =-30</u>

                                       0    = 0

Given that a random sample of 160 car crashes are selected and categorized by age. The results are listed below. The age distribution of drivers for the given categories is 18% for the under 26 group, 39% for the 26-45 group, 31% for the 45-65 group, and 12% for the group over 65.

     

<26 26-45 46-65` >65  

Observed  O 66 39 25 30 160

Expected  E 40 40 40 40 160

     

Chi square      

(O-E)^2/E 16.9 0.025 5.625 2.5 25.05

Thus we get chi square test statistic = 25.05
