Answer: No
Step-by-step explanation:
Considering significant: p <= 0.05
A multiple choice question has 18 possible answers, only one of which is correct.
which means that the probability is 1 out 18, so
p = 1/18 = 0.056
As 0.056 > 0.050
Then, it is not significant
Answer:
x=2
Step-by-step explanation:
-2x+4=6x-12 Add 2x to both sides.
<u>+2x +2x</u>
4=8x-12 Add 12 to both sides.
<u>+12 +12</u>
16=8x Divide by 8 on both sides.
<u>/8 /8</u>
2=x
