Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.

(9x−6)=14
(

)(−6)=14(Distribute)
6x+−4=14
6x−4=14
Step 2: Add 4 to both sides.
6x−4+4=14+4
6x=18
Step 3: Divide both sides by 6.

Answer:
Result is statistically significant.
Step-by-step explanation:
Given that :
Chisquare statistic, χ² = 67.81
Critical value for the distribution, χ²critical = 3.84
α = 0.05
The Decison region :
If χ² statistic > Critical value ; Reject H0 ; this. Eans that result is statistically significant.
Therefore, since, 67.81 > 3.84 ; This means that the result is statistically significant at 0.05

The correct answer there is the first option
Answer:
sin (2A+2B) = 0
Step-by-step explanation:
Given that,
cosec A= -2 and sec B= -2, A and B lie in the same quadrant.
We need to find the value of sin (2A+2B).

And

To find the value of sin (2A+2B) as follows :
sin [2(-30)+2(120)] = sin (-60+240)
=sin (180)
= 0
So, the value of sin (2A+2B) is qual to 0.
