Question

if X and y are related by 2x+3y +4=0 and as of X is 6 the the SD of y​

Answer 1

Answer:

2×6 + 3y + 4 = 0

3Y = -16

Y = -16/3

Answer 2

Step-by-step explanation:

$2x + 3y + 4 = 0 \\ \\ x = 6 \: \: \: \: (given) \\ 2(6) + 3y + 4 = 0 \\ 12 + 3y + 4 \: \: \: = 0 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 3y = - 4 - 12 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \ 3y = - 16 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: y = - \frac{16}{3}$
