The test for a single variance using the Chi-Square distribution is given by χ 2 = ( n − 1 ) s 2 σ 2 . If n = 2 , s = 9.84 , and σ = 8.47 , find χ 2 . Round your answer to 3 decimal places. χ 2 ≈

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

19

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
