Is -1.393 the significance level and if so what’s the degree of freedom?
Answer:
-2/3= x
Step-by-step explanation:
<u><em>square all the terms on both sides to get rid of the radicals:</em></u>

<u><em>exponent 2 and the radical cancel each other:</em></u>
1 + 1 - x = 2x + 4
2 - x = 2x + 4
<u><em>like terms on each side ( when you move one term tp the other side, it changes its sign ):</em></u>
2-x = 2x+4
2-4 = +x +2x
-2 = 3x
<u><em>now to keep the x alone, divide both sides by 3:</em></u>
-2/3 = 3x/3
-2/3= x
Step 1: Simplify both sides of the equation.
28 = −7

x
Step 2: Flip the equation.
−7

x = 28
Step 3: Multiply both sides by 2/(-7).

x=−8
Answer:
x=−8
