Ryan, sasha, connie, and lawrence completed the following proof. who completed the proof incorrectly?
given: 3x+7=5x-11
prove: x=9

a) ryan
b) sasha
c) connie
d) lawrence

The person who completed the proof incorrectly is:

                 Option: B

                   B)  Sasha

Sasha was incorrect with her proof.

She followed as follows:

( She subtracted 3x from both the sides of the equation)

Hence, the property is subtraction property of equality.

She added 11 on both the sides of the equation.

Hence, the property is addition property of equality.

she divided both side of the equation by 2.

Hence, the property is division property of equality but she called it as a subtraction property of equality.

The probability of not getting two consecutive greens is 1 minus the probability of getting two consecutive greens. Since the spinner is fair, the probability of getting a green on any one spin is 4/9 . Since consecutive spins are independent, the probability of getting two consecutive greens is (4/9)2 . Therefore the probability of not getting two consecutive greens is

1−492=1−1681=6581≈80.2%

hope this helps
